Hi Steven, A thought - as an alternative to using a camera, find a scanner/photocopier multifunction device gadget thing, and stick the circuit board on that - it creates much better images. Some of them have a scan to pdf or tiff, and then fire it to an email address or ftp server - that's what we've done here.
