Just a comparison of techniques. Top photo is an image from a flatbed scanner, lower one from a digital camera. Scanner gives quite a good image but lacks the depth of field that can be obtained with a camera.

Scanning may be a good alternative technique. Many images in the "Atlas of Russian beetles" (Zoological institute RAS, SPb, here is their great coleopterological site) are taken by scanning, e.g. these very large stag-beetles. DOF depends on the scanner type (CIS-scanners has tiny DOF, CCD-scanners - large DOF) and on concrete model, too...


scanning is also very good for dragonflies (i used that many times)... and also for plants. this was before to have a photo camera, anywai in many case scanning is a very good alternative
