For instance, if you go to Home Depot, every item has a white background containing absolutely nothing.
I simply don't believe that each and every item was photographed on a perfectly white surface that shows absolutely nothing else, not even texture. There *must* be a technique for removing the actual background that was present when the picture was taken yet preserving the border of the item perfectly. I'm very curious to know what that technique is and if I can do it in GIMP.
Even just knowing the name of the technique would be helpful but a link to instructions or a video detailing the technique would be even better.
Well they do... The photo setup requires several lights, a couple to light the subject, and one to blow out a white background, which is overexposed on purpose and therefore pure white. If this white background is a vinyl sheet there is absolutely no texture to it (and it is likely completely out of focus anyway). The set up isn't very complicated and for 20 minutes of setup (factored by the hundred shots...) you save all the editing time.
Otherwise using a background of a known color that doesn't exist in the subject (greenscreen) greatly eases the editing.
