Mineral Photographyusing immersion to photograph inclusions in rough crystals
25th Sep 2015 19:10 UTCDennis McCoy
this first one is a simple stack of 2 photos
in this one you can see some small bubbles held by surface tension. Each one reflects a tiny image of the light ring.

A couple of things you might like to try:
- Use isopropyl alcohol rather than water as your immersion fluid. Higher refractive index and will eliminate/much reduce bubble formation and reduce unwanted reflections more than does water.
- Replace your china pot with a cut-down dixie cup. Place the dixie cup on a small low voltage light table (cost about 20-25 bucks) use that as your main light. In general, transmitted/side-lighting works best for illuminating inclusions in crystals. The translucent white of the thin dixie cup improves the diffusion of the light from your light table (that should already be fitted with a partially effective diffusing screen).
- Work on critically sharp focusing and also try increasing the number of shots in your stacks.

You may have to adjust the curve of the broom clip to assure of a secure firm grip of the usb microscope. A standard hardware store should carry these clips. Lacking thread holes you could either glue a correctly sided nut with a shim for proper fit or a temporary setup with shims and rubber bands or plastic tie clips.

Working with a camera and with some cropping of the image file, I find I can make decent images that have about a 1 cm FOV.
