Due to some personal issues here, I have not had the time to devote to this exercise that I would have liked. But I have had this idea floating around in my head for the past week or so that I wanted to work on. I've haven't been able to devote the time I would have liked but here is a concept image if I may.
My idea started with a curiosity to see how flower close-ups would work (or not) in IR. I just got my IR-converted Rebel XT back earlier this week and only had very limited time to play with it. I have noticed though that exposures aren't as straightforward in IR as I might have thought. So I started wondered about bracketing and using Photomatix HDR software to "fine tune" the exposure.
So that was the concept that I began with. I had hoped to try different flowers, different backgrounds, etc. but time won't allow. So here is an example of where my thinking has lead so far.
The flower is a Mock Orange. I liked the shape of the flower and the fact that it was already white and would work nicely with the white leaves from the IR exposure. I also like the arrangement of leaves about the flowers.
Using the IR-converted Rebel XT and a 50mm f/1.8 lens with a 12mm extension tube mounted on a tripod, I made a series of three images exposed at -2 EV, -1 EV and 0 EV. Using Photomatix, I created a HDR composite image. Then I imported the HDR image into Lightroom where I made some basic adjustments before passing it on to PS4 where I added the Sepia tone and did a bit sharpening and noise reduction.
I did make images at a variety of aperture values from f/3.5 to f/22 but settled in on this series made at f/18. Since I am really neither an wide open nor a f/22 person, I felt it was fair game.
Original exposures were:
1/13 sec @ f/18; -1 EV; ISO 200
1/25 sec @ f/18; -2 EV; ISO 200
1/6 sec @ f/18; 0 EV, ISO 200
