A nice, strong composition with a perfectly harmonious background.
I'm not sure what is going on on top of the head. There should be three ocelli in a triangle but there are rather more bulges of about the right size.

My images are a medium for sharing some of my experiences: they are not me.

Nice shot! Like the 'tongue' sticking out! Also like the monochromatic silver look you've got here. Due you think that's due to the aluminium reflectors you used?
I see what Harold means about the simple eyes, but I notice some drops of water on the compound eyes (Same problem as me, too impatient to get stacking once the bug is out of the fridge!!) so I wonder if some of those bumps on the head are drips of condensation. It's definitely not a stack alignment issue as that would also be apparent in other areas of the image...
What software did you use for the stacking, and what did you use to do the focus steps?

Yes I meant to say that as well. The flash highlight on the top of the left eye does appear slightly burnt out on my monitor too, but I appreciate this can be a difficult balancing act!acerola wrote:Maybe a little too light at some places on my monitor
I suspect Antonio may have his screen setup slightly darker than mine!

Monitor settings won't matter much. Portions of that area are full of 255's so they will appear pure white on any monitor.lauriek wrote:The flash highlight on the top of the left eye does appear slightly burnt out on my monitor too
But I assumed this was intentional, in keeping with the somewhat stark "silver" theme.
It is a vexing tradeoff.
For scientific purposes, we normally want photos where nothing is blocked up or blown out -- no pure blacks or pure whites.
But such images often are not as striking as more contrasty photos where actually some information has been lost.
Sometimes the best one can do is to shoot with slightly "flat" illumination so that everything gets captured, then punch up the contrast later if appropriate for a particular audience.
