I'm new to IR photography. I'm trying to get the white colour out of green plants (leafs, grass etc.).



Here is my setup:



  • Canon EOS 100D full spectrum - IR filter in front of sensor removed

  • Samyang 24mm f/1.4

  • Zomei 680 nm IR filter

I'm using Digital Photo Professional 4 to set the white balance.



Below a photo where white balance is set on the green colour of plants.

The second photo white balance is set on a white sheet of paper.

Am I missing something? Why I'm not getting the white colour like on all of the photos on the internet?



I don't have any experience in post-processing and I do not own Photoshop or Lightroom so if there is something else I should edit in the RAW files please suggest what software I should use.



Is there something else in the camera or lens that might be blocking the IR light?



Here is a link to RAW file of the above photos:

EDIT:
I did a small experiment. I used a filter that was removed from my camera which should block all IR light. I did two photos: with and without the 680 nm filter. So in theory the camera filter should be completely black when taking a photo with 680 nm filter which blocks all visible light. Here is the result:



visibleinfrared



As you can see the camera filter is not completely dark so either the 680 nm filter is passing some visible light or the camera filter is passing the infrared light (or a mix of theese two?).



Can that cause the plants being not white in the IR photos? Maybe I should try a deeper infrared filter like 850 nm or 950 nm?

  • As to software: Canon's free-to-use Digital Photo Professional comes into mind +as do DigiKam and Darktable). Does not seem to me that RAW (or a misplaced WB, for that matter) is the issue here, though.

You're not missing anything - some epic post production is pretty much always used to create digital IR images.



Life Pixel is a company that does conversions, but they've also put together an extensive list of video How-To's for post.



To boil it down, you need to use a program like Photoshop or Gimp and get familiar with the channel mixer. When converting to black and white using this tool, you get to select which color channels map to the brightness of the black and white. This allows you to select which colors become white and which colors become black, and every shade in between.



There are other ways, of course, as there always are with post. But, this should get you started.

  • Thanks for an answer, have a look at my edit above. I know post processing can make a huge difference but even without it the plants that reflect a lot of IR light should be brighter with 680 nm filter on, here I cannot see any increase in brightnes of leafs on the trees (grass on my photo seems a bit brighter but it is due to fact that it's dry and in visible light it has light brown colour).

  • @Luke sorry i didn't catch the filter before. Visible light goes up to 700nm. So, yes, you need a new IR filter that blocks at least up to 700nm.
