 By way of example, I like this photo:

 although I guess one could say the depth of focus is not really that great (?).
 (It's the internals of a late-60s nixie desktop calculator (the diode farm
 is discrete logic gates, of course). It was sent to me by a fellow calculator
 collector a few years ago but I don't know what camera equipment was used.) 
A Caplio RR120. JPG captures on digital cameras typically put some text
as a comment at the front of the jpeg file, containing hardware, time, date,
sometimes the shutter/aperture/flash settings, etc.
