When I am taking my photos, I tether to my computer and have a live view of each shot. This is using Canon’s Digital Photo Professional 4 software.
One of the things it allows you to do is magnify the live view by 5x or 10x. So I used the 5x and focussed in on this fluorite crystal, and then used the Microsoft Snipping Tool to grab a screen shot.
So this is a single shot image. The fluorite measures about 0.038mm.
