Long exposures? Exposure stacking?

I applied a thin film of colored varnish to the top of a small LED and then grew a crystal "headdress" around it.

Fun. I love internally lit, additive processes.

But... no time lapse of the growing crystal?

I want to repeat the experience on a more powerful LED capable of sending light through a thicker layer of long, acicular crystals.

Have you considered playing with very long exposures. I've photographed things that would normally be considered "opaque" with exposures in the minutes, hours, or days. Seriously. Couple of thousand 1 minute exposures, averaged.

Same technique for very low fluorescence. I have this lovely triple-pyramid deep purple fluorite that usually needs hour long exposures to capture its fluorescence at 365nm with a woods filter on the light source and a 415nm high pass on the camera.

~23mm FOV, 90mm Macro lens on Sony a6300

The term "mirrorless" is totally obsolete. It's time we call out EVIL for what it is. (Or, if you can't handle "Electronic Viewfinder Interchangeable Lens" then Frenchify it and call it "LIVE" for "Lens Interchangeable, Viewfinder Electronic" or "Viseur électronique").
