Quite photogenic, I thought. About 200um diameter. The annoying glare at top left is due to a nearby spicule in the strew. Sorry about that.

If anyone has any sodium polytungstate going spare, I could fix that on the next attempt :)

Nice picture of a well preserved fossil diatom.

Photoshop is easier to source than sodium polytungstate, so why not use it instead to fix the glare? Probably safer too, although I know that many find it to be mind altering if used to excess.

Just open the file in Photoshop, and create a new layer above it. Set the layer blending mode to overlay or to soft light, and fill the layer with 50% gray. Then paint with black on that layer with a fairly small soft edged brush with the opacity set low - say about 8%. Two minutes and the glare will be all but gone. If you go too far, you can always undo mistakes by painting with white. Also, it is often easier to go a little past the effect that you are looking for and then to lower the layer opacity a little.

For the very edge, you may want to use a harder edge to the brush and zoom in to a view of 400% or more.

Hope this helps,

You could also try using the burn tool set for the midtones.
