More focus-stacked minerals

Here are a few more of my collection...
These were shot with a speedlight beside them pointing straight up at the ceiling. When scanning through the individual shots, the exposure is surprisingly different. I was expecting to get stripes of lighter and darker effect, but photoshop does a good job of averaging them out, I guess.

Slab of polished felspar with blue opals

A great favourite with kids! This is a slice of coprolite, fossilised dinosaur poop...

Pyrite sun crystal. Would look more imposing face-on, but this was a stacking exercise, so...

This is a crystal of Bismuth, it was labeled "Blue Gold Rainbow crystal"

Super shots of some beautiful and interesting subjects, Phil! I would love to see more of your collection, so please do keep posting.

I will be posting a few more tomorrow, and hopefully shooting a few more too. That's the plan, anyway! My favourite so far is the feldspar with opals. I have another slab of something, forget what, but it is studded with rubies! Nothing saleable, of course, but rubies never-the-less.

Super set, Phil. The last one is especially spectacular. :D :thumbup:
Yeah, that one was quite tricky to get. There are so many angles and planes heading away at different depths.
I really do like how well PS processes them, I have to admit. I had downloaded another program which someone had suggested, but really, I don't see any need to learn a new program when a couple of hours in LR & PS gives me satisfying results.
I guess that is my description... I wouldn't class these as 'good' necessarily, but they are very satisfying... My first attempt was horrendous. I was just using the ringlight, and its flash doesn't fire (usually...), but I had left ISO on auto, and the camera jumped up to some ridiculous number. There was so much noise that you couldn't tell where the rock grain ended and the noise began. I have a couple of ideas that might make the process even better, but for the moment I am happy to do it this way.

I don't think I have many which are fluorescent, but there may be one or two in there somewhere.

The bismuth is particularly impressive. How many shots in that stack? Which stacking program did you employ?

There were 10 individual shots in that one. I do the stacking by passing everything from LR to PS CC. I know there are more specialized programs out there, but I really like the way PS handles it.
