    Good, helpful post re circuit board photography. To append to this post: I created a jig with dimmer-controlled, switchable U/B white LEDS, which can uniformly light shadowed areas between components, (plywood, wood-glue, fiber glass epoxy resin to strengthen structure). Base has 4 long-bolt full-threaded "legs" screwed through 8mm nuts to adjust height, apex of wooden pyramid frame has felt-lined "bed" with rectangular hole to suit cell-phone/digicam. 3200x2200 pixel res (300DPI) gives a fairly sharp JPEG. As for the PCB tracks, photography works reasonably, but for greater accuracy, (eg duplicating a PCB) I prefer scanning on a flatbed at high res (anything from 600-4800 DPI), increasing contrast, then photo-editing with "line" and "paint-fill" tools to get an exact replica of the board tracks. (Without reflective solder flares or copper-side components obscuring track). Takes time, but satisfying result. Then Pixels/in gives you exact DPI to use for identical print size. Or if printer has preset fixed DPI then DPI*in gives size of required pixel-distance (of board).

    I was thinking of making "rails" over the circuit board to make a set of photos and then merge them to one big photo using photoshop. Rails is needed to move camera on them to make photos on the constant angle and distance. And because my hands shakes while rails don't.
