Calcite and Wulfenite from Tombstone, Arizona

I used the MPE-65 set at 4x and f/2.8. I set exposure to manual and 1/15 of a second.

Lighting is one Jansjo lamp with no diffuser. I set my color balance to 3600K.

I am using a 25 micron (0.025 mm) step size, which is 15 motor steps for my rail. I set the bottom focus to 050 and the top to 800, which yields 51 exposures. I took manual exposures to check things, but forgot to delete them. I delete them when the series finishes.

I had lightroom directly capture the images, which it saves as CR2 files. When it finished, I used Ctrl-A to select them all, then used the lightroom export to generate TIF files, putting them back into the same directory without resizing or renaming.

Now I go to my linux machine and start Zerene. I close my last project. I use File -- Add Files to bring the TIF files into Zerene. Once they were in, I use "Stack All, both" to do the stacking. I do just a little retouching

Next, I to to lightroom (back on the windows machine), find the final TIF image in the 2022_minerals folder and import it into lightroom.

I end up with this. The field width is 4.7mm
