• perspective control, shift and/or tilt lenses

• photography of buildings is a very specialised area of photography with its own very demanding OCD requirements, particularly with respect the the need for perfectly straight and level lines

• this type of photography generally has a very strict emphasis on straight lines and lines parallel to the image frame, so for this to work well for you, you generally need:
  • a a wide angle tilt-shift lens
    • this should be perfectly corrected optically with barrel or pin-cushion distortion
  • a geared tripod head to make fine adjustments to the angles to ensure your camera is perfectly level
    • eg. Manfrotto 410 Junior Geared Head
• if you are shooting interiors, you often need to back your camera up against a wall or corner to get the shot
  • a camera with a swivel out, rotating rear LCD screen becomes your life saver for composing these images and negates the need to get behind the camera
    • even better if you can remotely control the camera and see the composition etc remotely on your smartphone as with most modern digitals - this allows you to be out of the frame in these tight corners without having to resort to the self-timer
• a high resolution camera with excellent dynamic range helps for those high contrast scenes
  • Sony a7R III full frame mirrorless camera but unfortunately this does not have a swivel rear screen
  • canonrp or Canon 6D Mark II full frame dSLR although do not have the dynamic range of the Sony but they have a swivel rear screen
  • Olympus OM-D E-M1 mark II can use Olympus Hi Resolution mode and has a swivel rear screen but dynamic range is not quite as good as a Sony full frame, and the 2x crop factor means there are no super wide angle tilt-shift lenses available as yet (adapting the Canon TS-E 17mm f/4L tilt shift lens gives you 34mm FOV), but you can do in-camera, live keystone corrections so you can better compose your images in-camera
• remotely fired strobes
  • especially for interior work and potentially for those typical flattering, aesthetic, blue hour real estate shots
