Yea I use those flashes off camera only with optical slave units. They are used to add either fill light or highlights to add more shape and interest to the lighting in the photo. Robert Manning sent me an e-mail and said he had posted 2 photos in the AAW GAllery. He shot them with on camera flash. Absolutely nothing wrong with this if it meets the criteria of your needs. In this case it's simply to show some great work to other turners without having to spend a lot of time working on the photos. The pieces aren't very glossy so the hotspot in the middle is not too obnoxious. There are of course hard shadows around the piece, but again, what does it matter in this case. We can see the work clearly and define it's shape and color. It's sharp and well focus so it serves it's intended purpose of showing us the work. I also shoot pieces with on camera flash when I want to show people the work but it's not a piece I need to shoot seriously. Good job Robert I've always liked those pieces where the pith is oriented to purposely create a warped look. I want to stress that it's not my goal to put anyone down for the photography they do. It's only to try and help you get better images of your work to show it off. It's up to you to decide how far you want to go.
