The color blind photographer – just under 10% are color blind – here’s how you might be able to manage it

Written by Gary on April 4th, 2019

Colour visual impairment is very common affecting around 8% of males and 1% of females of those with European ancestry, and those affected see the world differently to non-affected people and have a significantly reduced color vision palette.

Most people probably will not know they are color blind but one can easily test yourself via this online test that Enchroma provides.

How does color blindness occur?

There are 3 types of cone cells in the retina each of which detect a different range of colours, blue “S” cones, red “L” cones and green “M” cones (S, L, M refer to short, medium and long wavelengths of light).

The OPN1LW and OPN1MW genes (responsible for red and green cones respectively) are located on the X chromosome, whereas the OPN1SW for blue cones is on a different autosomal chromosome.

The far majority of color blind people have Deutan blindness (6% of all males and 0.4% of females of European descent have a partial form called Deuteranomaly ) which is inherited from the X chromosome, so any male with this gene will be affected, but females generally require both X chromosomes with the defective gene to have color impairment. If a mother has only one chromosome affected, 50% of her sons will be affected and 50% of her daughters will be carriers. If a father has the gene, he will not pass it to his sons but ALL of his daughters will be carriers.

In addition, 1% of males have no green receptors which is called Deuteranopia in which greens look like dark purples , while 1% of males and 0.01% of females have the milder red receptor deficiency called Protanomaly and another 1% of males have no red receptors which is called Protanopia in which reds look like dark greens. Extremely rarely (1 in 100,000 people) have an inherited blue cone deficiency called Tritanopia which may also be acquired due to various eye conditions and can cause confusion between blue versus green and red from purple.
There are other extremely rare forms of severe color blindness such as blue cone monochromatism in which both red and green cones are defective, and Achromatopsia in which there is no color vision but only shades of grey.

If one has an extreme form of colour blindness, this will usually prevent you passing your driver’s license testing and you should give up on most commercial photography other than B&W photography.

How does Deuteranomaly affect you as a photographer?

Those with Deuteranomaly will usually have most difficulty seeing certain shades of pinks (which may look grey) and purples (which may look blue) while other hues in the reds, yellows, oranges and brown range may look similar especially in low light.

This means that when one is editing photos, they may over-emphasize certain hues such as pinks which can be problematic when editing skin tones, and when styling a fashion shoot, the colours may well be not as complimentary to each other as they perceive.

How can a Deutan mitigate these issues?

Some companies sell expensive glasses designed to “improve color vision” in those with milder forms such as Deutans. An example is Enchroma who makes glasses that filter out certain wavelengths to “reduce confusion” and reduce the overlap of colour detection between the red and green cones.

Unfortunately, whilst these glasses may provide a more colorfully vivid experience of sunsets by allowing one to see more pink and purple hues, a study has shown they do not provide a more “normal” visual perception, nor do they correct your vision to pass color blindness tests.

However, there is help at hand for those photographers editing their photos or viewing digital images in the form of software correction.

Windows 10 seems to do an excellent job of correcting color vision for digital displays – just go to Settings:Ease of Access: Color Filters and turn on Color Filters and select the deficiency, for a deutan this would be the deuteranopia setting. Once this is set you may even pass the online test that Enchroma provides and be given “normal vision”.

Apple iOS devices have a similar setting but in my experience is doesn’t seem to work as it makes the reds appear pink when they should be red despite of which intensity you set and when re-running the online Enchroma test I now get a Protan result irrespective of intensity suggesting there is a problem. The setting is found at Settings:General:Accessibility:Display Accommodations:Colour Filters then you can turn this on and then select which type and the intensity whilst viewing a color palette.

Back road 4WD adventures in East Gippsland, Australia

Written by Gary on March 26th, 2019

The Far East areas of Gippsland in Victoria offers many options for exploring (preferably with a 4WD or perhaps a AWD SUV) remote coastal beaches and remote alpine cool and warm temperate rainforests.

You should expect that in most of these areas there will be NO mobile phone coverage and hence no internet, so you need to plan for this in advance – ensure you have road maps (if hiking, then appropriate topographic maps), advance downloading of Google maps (and other phone maps) for offline use, and if you are hiking then you should take a pre-registered radio beacon EPIRB (and ensure you have updated your account with your trip details and car registration).

In addition, once you leave the main towns or Orbost, Nowa Nowa, Buchan and Cann River, you should expect to find NO food shops or petrol stations, so you need to ensure you have a full tank, plenty of water and some food.

Finally, before you go, check the Vic Emergency app to check for bushfires and road closures which may impact your trip and check the weather forecast – storms or wet weather are likely to create dangerous conditions or at the very least make some of the roads far more difficult to negotiate with slippery roads, potential trees blown across them and possible fires due to lightning strikes.

The McKillops Bridge circuit

This is full day trip is possible perhaps even with a 2WD (in dry conditions with care and skipping the Balley Hooley camp ground segment) and starts from Orbost and can return back to Orbost (or various other return routes can be taken).

The 1st segment from Orbost to Balley Hooley camp ground

There are two main alternate routes via Buchan where you have the option of visiting the Buchan limestone caves:

“Scenic route” via the Snowy River valley on the Orbost-Buchan Rd:

  • an option is to take a side route to Stringers Knob Historic Fire Tower by turning left at Monument Track and further on to Mottle Range Flora Reserve (the only known naturally occurring stand of E.maculata – spotted gum in Victoria)
  • from there head to Buchan on the Mottle Range Rd (84min, 63km to the Basin Rd intersection)

The “Google route” via the main highways:

  • take the Princes Hway to Nowa Nowa then up to Buchan
  • take the Buchan-Orbost Rd and turn left onto Basin Rd (55min, 76km to this intersection)

Balley Hooley camp ground

This is a nice, small free camp ground where the Buchan River joins a bend of the Snowy River which makes it a nice spot for canoes and kayaks and perhaps a swim but the shores are rocky without sandy beaches and the water can be muddy. You will need a AWD or 4WD for the somewhat steep segment of gravel road down to the camp ground with some ground clearance required.

Snowy River at the very remote camp ground

Tulloch Ard forest drive

This is a nice drive through various types of forests northwards until you reach some lovely alpine vistas and head back to bitumen at Butcher’s Ridge.

This section offers a few side routes including:

  • Basin Creek Falls – apparently great views and walk to falls
  • Ash Saddle – walking track and picnic area (750m walk)
  • Tulloch Ard Lookout walk – 3.2km return 1.5hrs, mostly easy with some steep sections and rough surfaces and steps

Once back on the bitumen, head north through Gelantipy (no shops or fuel) to the McKillops Rd junction and take this road north-west, through some very nice forests to Little River Falls.

Little River Falls to McKillops Bridge

This 16.5km segment of road is NOT recommended for vans as it is one of Victoria’s most precarious roads – a winding, downhill narrow gravel road with many blind corners and very few options for room for another passing car with a steep cliff on one side – take it slowly and with care as it is not a one way road!

Little River Falls picnic ground is on the side of this road at the start, although unless there have been rains the river is likely to be dry, but it is a nice spot for a bite to eat.

There is a side option to drive to the Little River Gorge Lookout which overlooks Victoria’s steepest gorge, although you can still see some of this further down the McKillops Road as shown here in this panoramic stitch I took:

Panoramic stitch of the view over Little Gorge from McKillops Road

As you are now heading down the north slopes of the Great Dividing Range, it becomes noticeably hotter and drier with more stunted mallee-like forests around the bridge area with temperatures some 5degC warmer

There is a Little River camp ground on the way down, and you can also camp on the north-east side of McKillops Bridge – both are free camp grounds.

Deddick valley drive

From McKillops Bridge you drive along the cliff face overlooking the Deddick River on a winding gravel road which from my view, lacks photographic appeal and has no options for camping until you reach Ambyne where there is a suspension bridge and the start of a section with some free camp sites.

The road turns to a general south-easterly direction through to Tubbut and on to Bonang – neither have shops or fuel.

Not far from Bonang is The Scenic Gap Reserve and a 3hr steep walk down to the Errinundra Old Growth Forest walk – although you will need hiking poles and be prepared for snakebites as this is not only remote without phone reception but parts of the path are overgrown making it impossible to see a resting snake.

From Bonang, you have a range of return options.

  • bitumen highway to Bombala then to Cann River
    • this is probably your best option if you either need food or fuel, or you are running out of daylight or a storm is coming or been
    • Bombala is a good size rural town with a platypus centre and some interesting buildings
    • before getting to Bombala, the smaller town of Delegate has some interesting buildings and nice rural rolling hill views
    • the highway back to Cann River takes you past Coopracambra NP and there is a short side route to Beehive Falls
  • mainly mountain bitumen to Goongerah and then Orbost
    • Although this part seems popular with motorcyclists, I found this quite a boring winding mountain drive with the added issue of logging trucks, but the Goongerah camp ground is a lovely little free camp site alongside a clear stream which is well worth considering for an overnight camp
  • AWD/4WD gravel to Delegate historic area and Bendoc
    • historic gold mining area with river diversion tunnel
    • one can then head east to the highway to Cann River, or north to Bombala, or head south on Clarkeville Rd to the seasonally closed 4WD only Goonmirk Rocks Rd and Tennyson Track (see below)
  • AWD/4WD gravel to Gunmark Rd and Errinundra Saddle
    • side route to a walk up to Ellery View Lookout on the Errunundra Rd
    • option of going south to the popular remote Ada River camp ground then to Club Terrace, Lind NP and back onto the main highway between Orbost and Cann River
    • option of going south-west on the seasonally closed Greens Rd through nice rainforests to Mt Ellery, Big River and then back onto bitumen down to Murrangower and Orbost – this was quite a nice drive and gave views over the mountains to the south at Ocean View Lookout
  • 4WD only long gravel road to Combienar via Tennyson Track
    • this is seasonally closed and rated the hardest of the 4WD tracks mentioned on this blog post and takes you back through Combienar and then to half way between Cann River and Orbost on the main Princes Hwy
    • I didn’t get time to do this circuit as storms intervened
    • highlights include:
      • Goonmirk Rocks
      • Frosty Hollow free camp ground
      • Waratah Lookout
      • Queensborough River picnic area
      • Tennyson free camp site
      • Buldah where you can head east to the highway to Cann River
      • Three Sisters Lookout
Ocean View Lookout on a smoke haze day due to regional bushfires

Roadside goannas are common in this region, often found feeding on road kill, and in addition to kangaroos and wallabies, you may be lucky enough to see a lyrebird rushing back into the roadside scrub. At dusk and at night, there is the high risk of killing the nocturnal animals such as wombats.

Storms and bushfires are major hazards to consider when deciding on these remote drives in alpine areas, especially in Summer

Birds and goannas of East Gippsland, Australia

Written by Gary on March 17th, 2019

I spent the last couple of weeks camping in a tent in east Gippsland which allowed one to witness the habits of the various creatures – they all seem to have a time of day when they would frequent the camp site or go hunting for food on the beaches.

Before we start on the birds, one animal that is very common in East Gippsland and which you will almost certainly see on the gravel roads or in your camp site, is the Lace Monitor lizard or goanna which is around 4 foot long with a powerful tail and claws and some venom in its saliva like perhaps all reptiles, although unlike Australia’s venomous snakes it cannot envenomate to cause significant systemic toxicity, but it’s bite can cause local tissue damage and infection. They are carnivores and seek small animals, eggs or road kill. The ones around camp sites are very used to humans and will walk within a few meters but are generally wary and will not appreciate being approached, so give them their space and they will not be problematic to you.

Australia is well known for its venomous snakes – we have most of the top 10 most venomous snakes in the world – and it is fascinating how they appear to have evolved.

Toxin venom producing lizards (Toxifera) evolved some 200 million years ago and from these, snakes evolved some 120-150 million years ago by turning off the genes which make limbs. Australia’s elapid venomous snakes appear to have evolved from an ancestor of the sea krait snake which appears to have swam to Australia around 25 million years ago (there were apparently no snakes in Australia before that time) and this then resulted in all of Australia’s terrestrial Elapid snakes evolving as well as via convergent evolution, some sea snakes. Monitor lizards didn’t make it to Australia until some 15 million years ago, while it seems pythons didn’t come to Australia until around 8-14 million years ago.

Surprise giant bioluminescent ghost mushrooms light up the night

Written by Gary on March 15th, 2019

Whilst camping a couple of weeks ago in Victoria’s remote wilderness, there finally was a little rain after some weeks of dry, warm weather, and I awoke from my tent to find myself in the midst of glowing lights.

I thought these may have been glow worms with my bleary eyes but in the morning I investigated and discovered that ghost mushrooms (
Omphalotus Nidiformis ) had grown following the rains the previous day to over 30cm in diameter!

This was at least 30cm across!

That night I decided to get my tripod out and used my Olympus OM-D E-M1II with Olympus 12-40mm f/2.8 lens with noise filter = LOW, long exposure NR on.

Some of the mushrooms at night, 19mm, f/2.8, ISO 800, 60secs, sunny day white balance.

Another one, this time 32mm, f/4, ISO 400, 240secs, sunny day white balance using Live Time mode.

I have previously posted a blog on ghost mushrooms from western Victoria using an Olympus 25mm f/1.2 lens and an Olympus fisheye lens here.

 

Emergency replacement of your jammed seat belt – Subaru Outback

Written by Gary on March 13th, 2019

While I was holidaying in a wilderness area recently, my driver’s side seat belt mechanism in my 2006 Subaru Outback suddenly jammed and nothing I could do would un-jam it.

This is extremely problematic as not only is is dangerous to drive the car without a seatbelt (in fact, probably more dangerous in a car fitted with air bags as the airbags are then likely to cause a hangman’s fracture of your neck from hitting your head too low and hyper-extending your neck), but it is illegal in Australia and your car would be made un-roadworthy.

I spoke to the local mechanics who said there was nothing one could do to repair it and it would need a new unit.

Fortunately, I had access to the internet and by extensive Googling found that this indeed was probably the case, although some had managed to disassemble the mechanism (see videos at bottom of this blog) and un-jam the ball that causes the belt to lock – unfortunately, this did not appear to be a feasible option on this seat belt – and it did have prominent warnings not to try as it may explode!

I contacted my local mechanic who called Subaru and he informed me that not only would a new seat belt cost $AU1850 but that it would take at least 3 weeks to get from overseas.

Not happy at all!

I thus resorted to emergency measures and purchased a used one online from a car in which the air bags had not been deployed – and hopefully the seat belt explosive pretensioner device had also not been deployed and made arrangements for it to be shipped to me – having my car towed home on a 8 hour trip was not a preferred option!

I managed to successfully replace my seat belt with this emergency second hand one and although there were many steps which had to be considered, I managed to get it all done in an hour or so.

DISCLAIMER: the manufacturer clearly states on the seat belt that it should NOT be used in a different car – so following these instructions is at your OWN risk and for emergency use only until you can have your mechanic install a new replacement.

Here is what you will need:

  • a replacement seat belt mechanism which has not had it’s pretensioner deployed (check inside the tube to ensure the piston is in the same position as your one) and is not jammed (it needs to be held upright for the belt to be able to be pulled out)
  • 14mm socket
  • 10mm socket
  • socket extension head for the top panel bolt
  • socket wrench (you may need a longer than usual handle to undo firmly held bolts)
  • small screwdriver to disconnect the airbag sensor clips
  • Philips head screwdriver to disconnect the lower panel spring clip

Steps required to replace the driver’s side seat belt mechanism

  1. Move the driver’s seat forward as far as possible
  2. Disconnect the car battery to avoid accidental deployment of the air bags
  3. Remove the rear plastic cover of the driver’s seat right track rail
  4. Remove the rear door rubber seal (at least the front and bottom parts)
  5. Remove the plastic lower wall panel by pulling it at the top and bottom rear and then sliding it out of its front bottom catch mechanism, then disconnect from the rear bottom safety spring using the screwdriver to undo the screw holding the safety spring onto the panel.
  6. Remove the top wall panel by pulling out the small rectangular “Airbag” labelled segment at the top which will expose a bolt that will need to be removed using the extension attachment for your socket wrench.
  7. Remove the large black metal protector over the belt using the 10mm sockets to undo the bolts.
  8. Lift up the driver’s side of the rear seat (or fully remove the rear seat but this is not really needed), to allow you to free up the plastic protector panel that lies under the carpet – you will need to create enough room to give you access to the 14mm bottom bolt that holds the pretensioner into the car wall.
  9. Disconnect the two air bag sensors by using the small screwdriver to gently flip up their top plastic square which will allow the connector to disengage.
  10. Unscrew the plastic cap near the rear of the pretensioner device to allow it to be freed from the floor connection.
  11. Remove the 14mm bolt holding the pretensioner onto the car wall.
  12. Carefully remove the 14mm bolt holding the seat belt onto the car wall avoiding stripping the bolt edges – you may need a long wrench for this one as it is held very tightly).
  13. Remove the top panel from the seat belt by passing the pretensioner through the panels’ belt gap (you will need to play with the panel mechanism to achieve this).
  14. Put the replacement seatbelt in by reversing all of the above steps – check that the belt is coming out freely once it has been mounted, and note the final attachment of the upper panel needs to be positioned so that the up-down slider position corresponds with the up-down slider of the upper panel.

Hope this helps someone get out of a predicament – I presume the general principles will apply to most modern cars.

But what if you can’t get a replacement unit?

I have not tried this on my jammed unit, but you may wish to consider following these Youtube videos on how to dismantle your seat belt mechanism (against manufacturer’s advice) by removing the 3 plastic lugs holding the Do NOT REMOVE plastic covers on:

These are not Subaru models but you get the idea

If you are lucky you may be able to fix the jam by tapping the mechanism as shown in this video with the aim of freeing the stuck gravity ball which is the culprit (I tried this and it didn’t work on mine):

 

Walking with dinosaurs on the Bass Coast

Written by Gary on February 14th, 2019

Victoria’s southern Bass Coast around Inverloch is not only a lovely place to spend Summer at the beach and explore the surrounds, but it is also a walk into the past.

The sandstone rock platforms date to around 120 million years ago (mya) which was during the Cretaceous Period and it is fascinating to try to consider what these times were like.

To do so requires a bit of an understanding of Australia’s place in the world then and its climate.

Southern Australia with it’s connection to Antarctica intact had moved from the northern Hemisphere where it had been some 550 mya, to close to the South Pole as part of the Pangaea super-continent.

During this migration south, around 360mya, during the Carboniferous Period when ferns, seed ferns, horsetails and gymnosperms evolved, conditions were warm and tropical which resulted in massive “Coal forests” dominating the land until the Permian Ice Age 280mya which resulted in ice glaciers covering most of south-eastern Australia (as demonstrated in Werribee Gorge and around Heathcote). These “Coal forests” became buried and are now the massive coal (as well as oil and gas) deposits which are being mined in various parts of Australia including the Bass Coast.

After the Permian Extinction event of 252mya, Australia became warmer and more monsoonal with the Triassic and Jurassic Periods, and much of Australia became large sedimentary basins with little evidence of Jurassic Period dinosaurs.

By 120mya the Australian craton had started migrating northwards but this time AWAY from the Antarctica craton creating a massive Rift Valley (similar to what is occurring in East Africa today). Africa had separated from South America (c140mya) which was still connected at its southern tip to Antarctica. Tasmania was at the South Pole.

This rifting created subsidence including the land between Tasmania and Victoria forming a massive flood plain with large rivers and many small rivulets at a time before the Ice Ages and well before Antarctica had become covered with ice and well before Australia had become an arid inland region.

120mya, the climate in this region was more of a cool temperate climate with snow on the alpine areas, long polar winters without sun and the rivers covered in ice. This was well BEFORE Australia had been populated by monotremes, marsupials, snakes or goannas but there were a range of Cretaceous dinosaurs and other animals.

Walking on these 120mya sandstone rock platforms, one can easily see today remnant fossilized trees which had fallen in the silt, and each year researchers come to dig the coast line looking for small dinosaur fragments amongst the conglomerate rocks remaining from the rivulets.

Conglomerate rocks embedded in sandstone from the 120 million year old rivulet beds – could any of these be dinosaur fragments – part of a rib, or a tooth?
I imagined this could be a foot print but I am guessing it is not
and this paler one different to the other rocks in this conglomerate could represent a tooth, but who knows – I am no geological archaeologist!
Even if one does not discover any dinosaur bones, it is a lovely way to explore the area and search for interesting patterns – a bit of mindfulness at the seaside.
Nearby is evidence of the resulting volcanic activity due to thinning of the crust with the rifting with flows of igneous lava / magma deposited above the sandstone and these have been dated to 99.9mya.

This leads us on to how Australia’s unique animals evolved and came to be in Australia.

The first monotremes evolved c110mya and whilst the first marsupials (early opossums) evolved c100mya in North America, they had to migrate to South America and then across the Antarctic (before the trans-Antarctic mountains were pushed up c50mya) arriving in Australia c55mya where they then evolved into kangaroos, koalas and wombats.

40mya, whales evolved from the hippopotamus and would eventually travel to Australian waters.

Australia is well known for having the most venomous snakes on earth, and it is interesting how these evolved.

Snakes evolved from lizards around 120mya, with the “Old World” snakes being the pythons which have residual lizard features.

The elapids evolved c38mya and arrived in Australia c25mya from the north perhaps from a close ancestor of the semi-aquatic Sea Kraits which had evolved at the same time.

It was around this time that Australia’s climate dramatically changed. Australia had already become much drier c38mya when the Antarctic started to develop ice sheets and duracrusts started to form across Australia. This arid climate accelerated when South America and Tasmania both had separated from Antarctica allowing the circum-polar ocean currents to form c27mya which would result in a freezing of Antarctica

Australian terrestrial Elapid venomous snakes then evolved over time into a range of closely related species including Eastern Brown and Taipan with their tolerance to the new arid inland conditions, the Copperhead and Tiger snakes, but also the Australian elapids evolved into vivaporous sea snakes (c16mya).

The Australian goannas (monitor lizards) and pythons arrived in Australia from the north c15mya, although the pythons may have arrived somewhat later around 8mya.

Presumably the ice ages of the Pleistocene (the last 2.8 million years) were a trigger for the evolution of Australia’s megafauna which tend to cope better in cold conditions. Yes, it is better to be shorter and smaller when there is global warming!

Homo sapiens evolved some 300,000 yrs ago, and around 45,000 yrs ago, Australia’s indigenous peoples migrated to Australia from Sri Lanka. In contrast, the Polynesians migrated much later, starting around 3000BC and migrated from Taiwan region to eventually cover most of the Pacific Islands, New Zealand and to Hawaii.

Bass Strait did not become the sea way that it is today until the end of the last Ice Age resulted in sea levels rising c8000 yrs ago which cut off Tasmania from the mainland.

More details on how Australia evolved is on my wiki page here.

 

Bushwalking with the Olympus 300mm f/4 lens

Written by Gary on February 9th, 2019

Recently I posted how my favorite walk about lens is the Olympus 40-150mm f/2.8.

If I am wanting to target smaller wildlife such as birds, then the more focal length reach the better, and the Olympus micro ZD 300mm f/4 OIS lens is a perfect lens for such ventures.

Matched with the Olympus OM-D E-M1II Micro Four Thirds camera, it becomes a unique kit which is:

  • incredibly sharp 600mm focal length reach in full frame terms
  • excellent weathersealing
  • fast and accurate auto focus
  • perhaps the heaviest kit I am prepared to carry in my hand for 1-2 hours on my short walks coming in at under 2kg – no other kit can give that telephoto reach at that image quality for under 2kg!
  • awesome level of image stabilisation (although the E-M1X will give even more image stabilisation)
  • ability to shoot at up to 18fps silently with continuous AF
  • ability to capture a burst of shots BEFORE you release the shutter button which is great for capturing birds taking off
  • ability to program the camera to ignore foreground or background when focusing by dialing in a focus range limiter – not just the one that is on the lens.
  • ability to shoot hand held 4K 30p video (although you do need to take some care in this to avoid too much camera shake as I had in my video below)

The down-side is that it is still quite heavy and the focal length is fixed so when you are about to step on a snake as I almost did, the lens to too long to capture it – and even larger animals such as kangaroos can be too close to capture.

Here are a selection of shots from yesterday:

No idea what bird this is (cropped image) but it didn’t hang around long (tree trunk darkened in post-processing) – Bald Hills Nature Conservation Park where I convinced my wife that even if it is remote, it is safe to walk – I was not aware this guy found 10 or so copperhead snakes in the wetlands there one afternoon – but then he went searching for them!

The snake I almost stepped on was near the entrance to the nearby Kings Flat Reserve. It was a shiny deep black colour and although I only saw the tail end as it slithered into the undergrowth, it looked to be about 1m long or so and I suspect it was probably a Red-bellied Black Snake.

Here is a quick hand held video using this lens, apologies for the shake, not even the wonderful IS could cope with my tired arms at the end of the day combined with my inexpertise at video work – something I rarely do but on this occasion my wife requested a video.
joey
Her mother was slack leaving this big burr on her neck, but he is still very cute!
and just to show how well this lens can perform even shooting into the low afternoon sun, the micro contrast and sharpness is awesome.
Another demonstration of the shallow depth of field and bokeh.

None of the above would have been possible had I used my full frame camera – they just don’t make a lens with the same capabilities in that weight range – as discussed in my earlier blog post here.

If I was a birder with plenty of patience and sitting in a hide with a tripod, then sure, the full frame camera with a 600mm f/4 lens may get better image quality – but at what price in terms of money and burden?

 

The apocalypse

Olympus 40-150mm f/2.8 lens with a bit of post-processing for ambience.

Taken at 150mm on my remote beach walk with an incoming storm on its way in the late afternoon.

This lens makes for a great landscape lens with its versatility and weather sealed capabilities and I love that it does not extend on zooming or on focusing which means less issues with salt spray or sand – just give it a wash under the tap when you are finished at the beach to avoid the salt corrosion risks – probably not important if it is the end of the world though!

I was walking along a remote desolate beach today accompanied with my Olympus OM-D E-M1 Micro Four Thirds camera and my trusty Olympus mZD 40-150mm f/2.8 lens, not really knowing what I would find.

The beach has protected areas to keep the endangered Hooded Plovers safe from beach goers as they can easily trample on the eggs or scare the young into hiding where they may die as the young are not able to fly away.

Beach goers are required to stay on the water edge to avoid disturbing them so I have do intention of shooting them – otherwise I would have taken the heavier Olympus mZD 300mm f/4 lens along instead.

Unexpectedly, this adult Hooded Plover (aka Hooded Dotterel or Thinornis cucullatus) came running along the sand as they do down to the water’s edge just in front of me allowing me to get a couple of quick shots in while he/she stood still – which is not a common thing as they tend to continually run around looking for food.

Even at 300mm equivalent focal length reach in full frame terms, the small bird at that distance still looks pretty small in the frame, and so this image has been severely cropped to show you what one of these lovely birds look like in the wild.

Yes, it is not a ground breaking exciting image of a bird in flight with the sun’s reflection in its eyes and a catch of the day in the beak, but it is more of a sentimental ambience as he looks out to sea.

Note he has been tagged as this species which is endemic to southern Australia and Tasmania is endangered as a result of:

  • human Summer beach going activities as this species breeds with a clutch of 1–3 eggs is laid from August to March, which is also the peak of the Austral summer tourist season with disturbance from dogs and horses on beaches.
  • predation by Silver Gulls, ravens and introduced foxes


 

Abstract sand textures from Wilsons Promontory

The patterns sand on beaches makes is always fascinating – what are the beach characteristics which create each of these unique patterns?

Taken with the Olympus OM-D EM1 and the Olympus 40-150mm f/2.8 lens.

Why bother taking these images?

I think they would look great as a complimentary wall piece which does not overpower a room in the way those epic landscapes would.

They also have a role in post-processing because you can use them to create a texture layer to superimpose on your main image.

Add a bit of magma from a volcano and you get granite … I think that is pretty cool!

Yes, these were also taken at Wilsons Promontory.

Not every image needs to be epic!
