The three things that matter in photography of edges

[grepper]

Mr. Cyrano, you said, "I've found Dino-Lite's embedded EDOF algorithm is good, and usually yields results comparable to stacking in Photoshop." 

I have a couple of questions:

Does the Dino-Lite produce a stacked image automatically or does it simply automatically produce a bunch of focus bracketed images that then require stacking in post processing with it's software the same as you would do in PS?

How many images is the focus bracketing?
