This is a close shot of a slab of Mary Ellen jasper I cut recently. The scale is just under a centimeter. Thanks for looking!

I like macro as much or more than most, BUT the wide shot wins hands down inthis case.
Is the saturation accurate?

These are wonderful pictures, jb. Do you know what the silvery crystals are in the first pic?

I agree, the wide shot is definitely nicer to look at; the first is more of a curiosity since we rarely get to look at it that closely.
The silver is hematite. Back when these guys were alive, there was very little oxygen and a whole lot of reduced (unoxidized) iron around. These bugs produced so much oxygen they essentially rusted the whole planet, and encased themselves in iron oxides at the same time.
The saturation on the second is not stretched, but the contrast is optimized. It looks very much like it does in bright diffuse sunlight.
