VERY cool images and mineralogy!

A view of some lovely frothy, almost pumice-y, basaltic lava from Kilauea's Lower East Rift Zone 2018 eruption. This is a stack of four frames (Focus Stacker on my Mac). Pentax K-50 w/ Tamron 90mm Macro, LED lighting in a tabletop lightbox. Four x f/8, ISO 100 https://images-wixmp-ed30a86b8c4ca88777...

Worked with a fist-sized mass of crystalline pyrite today. Sat it on a fence rail out on the deck, natural shaded light. Tripod and focus rail, Pentax K-50 w/ Tamron SP Di 90mm Macro. Images stacked on the Mac using Focus Stacker and a bit of editing in Gimp. Hopefully the links won't be a problem t...

Thank you. I agree, the URLs from that site are horrible. They made changes a while back and now we are stuck with that vs a decently short address. I did try a couple of times to get it right here, using the preview function, but could't get it. After submitting, I finally had to go back, resave th...

Not microscopic, just micro... The rock is a remnant washed out of some Puget Sound glacial deposits. Tentatively identified as a limestone (poss.) turbidite sequence. The field of view is about a half inch across. Surface was painted with water for the 7 shot sequence, stacked in 'Focus Stacker' on...

That is just flat-out gorgeous...

Agreed, if I can rearrange things to do so...

Thanks for all the ideas and suggestions. I think I'll try using boiled water first, and drop the rock in for at least part of the time. The edges of the dish are far enough from the rock that surface curvature is negligible, depth of water at the shallowest over the rock was 2-3 mm. Setup is shown ...

Hi everyone. First post here, so naturally it has to be a technical question... I am beginner in macro shooting, I love rocks, and a gravel side yard - so lots of subjects. I found one that has nice contrast and features, but only when wet. Submerged the rock in a dish of water, took a series of ima...
