Another Urchin

I know that I can do more with these......but I'm getting somewhere.

Go for a tigher crop and more DoF?

 

[Desi]

I tried that. When I crop too tight it just doesn't look sharp enough.

I'm not sure what is going on with the focus. I'm using extension tubes and a tripod. The focus looks good through my viewfinder on manual focus and I'm using f22 for maximum DOF.

I figure that either my extension tubes are causing an un-sharp image, or perhaps it's just the nature of a sea urchin at high magnification.
