I'm afraid I can't explain what I want to say but I will try... This is a question mainly to Rogelio (:
How do you make those stacks?I mean in usual way or not? The surface of waterfleas on your images is sharp, but guts remain unsharp or at least I think so. If I try to stack all middle shots contain part of surface and what is inside, and that - when stacked - makes an ugly effect: too many sharp surfaces one above another look bad put together.
Here are 'handmade' PS stacks:


Let's say there were 40 images in both. I did some 'pre-stacks' consisting of 5-10 images, and than stacked them by myself erasing shapr parts of guts. For me it looks much better than when both surface ad inside parts are sharp.
