Spores

Unknown Mushroom Spores at 10.7X
These stacks are not turning out sharp.  They have chromatic aberrations, too.  I am not happy!

Unknown Mushroom Spores at 18.2X
I decided after this shoot that I needed to correct for chromatic aberration.  That is not as simple as it sounds since the lens used for a closeup filter, Sigma 10-20mm, has chromatic aberration but does not register in camera raw.  I must select it.  Another factor may be that we are looking through it backwards.  The Sigma 180mm macro needs little or no correction.  Neither of there images is corrected.
