Just before leaving the farmhouse in the previous post, I decided to go back to the car and get my digital infrared setup – in this case, the Canon 1DMIII, Olympus OM 21mm lens, tripod & Hoya R72 filter.<\/p>\n

First an initial shot without the IR filter:<\/p>\n

\"normal<\/a><\/p>\n

Yep, it’s a nice old farmhouse, but the lighting had changed and it was now overcast and so as a color image it is a nice documentary image but not much more of merit.<\/p>\n

Let’s see how it looks in IR, firstly under cloud cover and I guessed an exposure of 30secs, f\/5.6 at ISO 100 which on checking the RGB histogram was pretty much spot on.<\/p>\n

Image white balance using Lightroom, levels adjusted in PS and cropped.<\/p>\n

\"cloudy<\/a><\/p>\n

As you can see we have a nice Wood’s IR effect with grass and leaves becoming almost white while the blue sky is almost black. The long exposure resulted in motion effects of the clouds.<\/p>\n

Just before I packed up, the sun came out and so I quickly guessed this one at f\/8, 20secs which resulted in a fairly accurate exposure on RGB histogram. Processed as for previous image.<\/p>\n

\"sunlit<\/a><\/p>\n

Personally, I like the sunlit image as the sunlight has created more local contrasts which adds to the image.<\/p>\n
