For Izzie -
Please, Izzie know that some cuts their lettuce and some tears it - meaning there are many ways to achieve the same result as what what I do. That said, here is my own setup:
1. You will shoot in a clearly delineated light to dark area. In this case, I shoot from my sun porch into my darkened livingroom. It would be better if I had a dark matte wall, but beige is what I've got.
2. Place your object to be photographed in front of the doorway.
3. Take your picture. I shoot manual. My settings were SS 1/100, focal length 82, f-stop 5.6, ISO 640
4. I processed in RAW, then in CS5.
I do lens corrections and noise control in RAW. I bring the image into photoshop, create a new layer, do levels - use the black eye dropper on the lightest part of the background and it will turn it black. My flower is now too dark, so I use my brush, set to clear, and brush away the dark layer from the flower only. I tried to do a screen shot, but I do not know how. I also cloned out the unwanted stem and debris at the bottom.
Here is the final image.
This is a very simple explanation of what I do. There are other small adjustments that i did make that were specific to this image. But, I hope this helps.
