I've got several photos of items (lots of white with color images) that are taken with a backdrop. I want to make the background transparent. Initially I used a white backdrop which was marginal. Then I switched to a light blue which wasn't much better. Finally I changed to a dark Navy blue background and I figured the high contrast would be ideal. Unfortunately I can't get rid of the background compleltely.
My first attempt was with Fuzzy Select and when I clicked on the background it turned the entire image red. Playing with all the settings (anti alias, draw mask, alpha channel) I just couldn't get it to work. Never could get the Feather to activate. So then I switched to Select by Color and that worked - mostly. The problem is that the backdrop, which is a solid color, has some minor undulations which cause slight variations in color density. The result is that some of these variations leave a shimmering effect which when saved aren't completely transparent. There's still lots of contrast between the image and background so that baffles me. I'm using Inkscape as the graphics editor and I'm a real amateur with Gimp so I could use come help.
