The colours are really nice!! Is this how it came out of the camera or did you make some adjustments?

Rowan - I've picked this comment up last, and previous replies go some way to answering the question. To recap: I use a grey card custom WB set in camera. The sensors pick up some colour not apparent to the naked eye (artefact of the system at least in part as the RGB sensors react differently to IR. Then, I tweak contrast, shadows, highlights, and saturation. Finally, I use some sharpening.

Many Thanks

David

Thanks for the explanation David. You mentioned the 40D was full spectrum converted. Does that mean that UV light comes through as well, or do you use a UV (blocking) filter?

Good point here,Rowan. This has been discussed at another time, but the upshot is that the Canon sensors are not that sensitive to UV light (Nikon ones are apparently). So I do not use a UV filter. Nevertheless,I ought to test the matter by using an IR filter plus and minus a UV one and see if there is any difference in the IR image. My gut feeling is that there is probably no significant UV input.

I suddenly remember reading somewhere that a lot of modern lenses already have UV coating... So that wouldn't help either.

Some may have, Rowan. There are so many coatings these days it is hard to know what is going through the lens. I need to check up.

For some reason, this photo drew my eyes immediately. All the different contrasts make a quite magical photo :onfire:
This almost looks as if it could be a group of flat insects gathered around something interesting :hug:
Great stuff :squee:

Many thanks, Pamela. You are quite correct in the perception - these do look a bit like a type of flat insect, the name of which I cannot remember. I thought these made some interesting shots, but I cannot decide on the "best". We shall see what others think.

Cheers
