Sorry this is off-topic here, but searches seemed to indicate this would be the best forum to post this off-topic subject. A friend asked me to photograph some of her paintings, and I've learned a lot (especially here) regarding lighting techniques, equipment choices, etc. I'm primarily a nature photographer, but it seems like I have the gear to do a credible job. I definitely don't want to stir up the MF vs SLR debate, but I'm using a D800e with the 85/1.8G at the moment for this task, and playing with cross-polarized SB-900s, though I'm not convinced the polarization is necessary for her work, which is matte finished with minimal brushstrokes.
I got unexpected feedback when she saw the results. At 100%, the file shows the canvas texture perfectly, and that horrified her. Hey, I thought lots of detail made for a great reproduction photograph. Apparently not in the art reproduction world.
I've played with lots of techniques to remove it, such as blurring, high pass filtering/masking, and FFT filtering. The last was the most successful, but still obviously reduces the detail some, and is a guessing game. She showed me results from some others she had done professionally before she moved to this area, and I see her point -- there is still high res detail, but the canvas texture has been mostly removed.
Can anyone help illuminate how to remove canvas texture in post processing, while retaining other details? Or does the lighting need to be different?
Thanks in advance.
