Based on some posts here on CR which suggest that IR photography is possible with an unmodified 5D3, I decided to give it a try and I ordered two clip-in filters for my 5D III:
1) 642 bandpass filter which includes a tiny bit of the visible spectrum in its transmitted light. It blocks again long IR, but is transparant for short-wave IR.
2) a classical 742 nm IR-filter.
My 5D is unmodified and I have no intention to modify it. If it doesn't work, I can still return the filters. Since I am complete unskilled in processing IR-images, I would greatly appreciate if some skilled person could take a look at a single raw file from each of the two filters. The questions that I have are:
1) Do the files look like normal IR-images compared to what you would get out of a modified 5D? Especially with the BP filter, I can imagine that if the lowpass filter blocks all IR-light you will end up with only red photos on your sensor and this is not good.
2) Could someone please load them into photoshop and spend a few minutes to see if it is any good or not with these two filters? If you drop me a PM, I can send you the CR2 files (two files, one for each filter + a no-filter photo of a gray card).
Thanx!
