Better detail in photos

Post by Koala » Sat Mar 03, 2018 8:51 pm

A couple of years ago I saw some microscope photos where peaks and troughs were different colours. Using different coloured L.E.D's almost gave it a 3D appearance.

Want to try and see if the technique would work on coins

But can't seem to find the setup up that was used.

Was that with a single optical scope?

Once into the field of stereoscopes etc. then it is ££££ ... I think fluorescent lighting is used sometimes.

I also read that archaeologists have photographic methods for detail, not sure which.

An alternative I might try is macro 3D modelling, there it is possible to raise and lower the plane, and sure to be a programme somewhere to add a colour gradient, would like to try 3D using a usb microscope at some point also.

has some 2D images of a 3D result , could not find any really detailed ones ( as in the hundreds of mm needed for some coins maybe) on sketchfab though.

Also an easy way to look through the patina would be good :D .
