Having read what various IR experts are doing, I waited for a very bright break in the clouds (which I am NOT complaining about - we desperately need the rain, but why oh why while I'm trying to play with IR??) and then photographed some bright orange nasturtiums - figuring that if they were bright orange in visible light, they probably have a fair bit of IR as well, for the bees to look at.
Because I was outside and it's a funny unsettled day, there was a fair bit of wind and so there's a good bit of movement on the petals. Not ideal but at this stage I'm not too fussed about that sort of thing.
This was shot with the K10D, Pentax 16-45mm kit lens at 45m, ISO 200, f/4.5, 24 seconds, RAW and then processed through Adobe Photoshop as follows:
1. Using a curves adjustment layer and the threshhold, I adjusted the levels to get a black black (not so much of a problem) and a properly white white - needed a much bigger boost.
2. Another curves adjustment layer to put a bit of an S curve on it.
3. Third adjustment layer to do the B&W conversion, pulling green up as far as it would go, red and yellow up a bit too, magenta down, and added quite a strong sepia tint.
If the truth be told I actually did the B&W first and then the curves adjustments, but that's the way they're stacked in the file.
The end result is starting to look as if it might actually be possible to do some work with this type of image. I think this is part of the fascination - it's become so easy just to point even a phone at anything and get an acceptable image that suddenly having to really WORK for your image is a real challenge. It gives one a sense of what it must have been like in the old days - the seriously old ones. Even I can remember having to use a light meter and I still use a manual flash. (For my sins!)
