Infrared photography and microstock

  1. 1. INFRARED PHOTOGRAPHY AND MICROSTOCK by Laurent Dambies April 2009
  2. 2. HOW DOES IT WORK ?  Visible light: 400-700 nm, near infrared 700-1200 nm. Above : mid infrared and far infrared (thermal imagery)  IR filter : block most of the visible light and let near infrared hit the CCD.
  3. 3. WHY INFRARED PHOTOGRAPHY?  Gives a dramatic, surreal effect, an ethereal white glow to the pictures  Foliage and grass reflect infrared radiations and appear much brighter in IR Different foliages have different IR reflectance as well as foliage affected by disease or insect infestation.  Blue sky and water appear dark.  Depending on the light, textures can be revealed in more details.  Skin also can give interesting tones.
  4. 4. CHALLENGES IN IR PHOTOGRAPHY Focusing and depth of field  Visible vs IR: different focus distance:  tricky to produce sharp images   If no lens with IR marking  Focus bracketing  Hyperfocal distance Exposure  IR filter very dark  indications given by the camera cannot be trusted   Typically 2 to 15 seconds exposure time  Tripod  Long exposure  interesting results on water and clouds 
  5. 5. Equipment  Variable results depending on body and lenses  blocking IR filter (hot mirror) on top of CCD’s  cameras more on less sensitive to IR. The hot mirror can be removed to make a true IR camera (or check on Ebay).  Flares or hotspots on some lenses 
  6. 6. My gear Canon Powershot G9 Lensmate lens adapter Hoya R72 filter 58 mm Hoya ND4 filter 58 mm Small tripod  Universal IR Hoya R72 filter: 50% cutoff 720 nm  some visible light get throught
  7. 7. CANON G9 SETTINGS  RAW @ 80 ISO, hyperfocale distance  Excellent tutorial here:
  8. 8. MY 10 STEPS WORFLOW Open Raw with LR2 Set color temperature 2000, tint -50 Remove noise Luminance 60 Chromatic aberration : all edges Export as jpeg or tiff Open in CS3 swap red and blue channels: red 0 blue 100, blue 0, red 100 Image--> adjustements levels blue and green Image ---> curves define gray point Import in LR2 adjust hue/saturation on the different channels. Export as jpeg
  9. 9. IR PHOTOGRAPHY AND MICROSTOCK Agency Infrared + landscape Infrared + building Shutterstock 526 106 Istockphoto 140 45 Dreamstime 540 124 Search done on April 09th 2009  Pictures difficult to be approved due to noise and softness  Some success on Shutterstock and Dreamstime
