Yep, I built it kind of a bit at a time- first I built the slide, then I wanted a way to position the camera for top down or angled shots, so I built the hinged thingy. I might be able to use less frames, but I keep my aperture as low as possible, because I don’t have much for macro lighting. It is like doing HDR-the more frames the better, since you would rather not use some than miss a critical one. I should experiment some more and see. So far, i just use Photoshop to stack them. Kind of slow, but it works, and I already have it, so I don’t need to buy Helicon or something dedicated.
