Closeup with stacking technology

A small pen test with stacking technology.
Another long winter night, I suddenly remembered that I had on the shelf in the closet gathering dust macro lens Canon MP-E 65mm. I rented it rarely, and one reason for that - too shallow depth of field. The more you install fold approach - the less it turns out.
Inspired by the masterpieces of some bloggers and poizuchat entry in his blog on the tag "Macro", I learned about a new technology for themselves shooting objects with high magnification. As they say, all genius is simple - it is necessary to make a series of shots, changing the distance from the object to the point of focus on the fraction of a millimeter. The result is a set of pictures, each of which dramatically out only part of the subject, well then process these images using appropriate software.
I was surprised that the version intended for this Zerene Stacker program exists for Mac OS. And I remember that I have a motorized slider, which, in general, is able to very slowly move the pad along the rails. And away we go ...
Here's a installation appeared in my room. It remains to find the subject.
For a long time I did not have to look for - went into the kitchen and picked up a grain of sugar. You see it, do you?
Okay, I shall prompt!
25 pictures, insert the memory card into the Mac, fed their program there ... This is a grain with a 50-fold increase! I do not know what sugar looks so beautiful!
The second attempt, another angle and a little play with the light.
The turn of instant coffee granules.
An increase of about 30 times - I found the smallest speck, but she managed to still not get the shot in extreme close.
Zoom. And this here, we fill with boiling water and drink in the morning ...
One of the original 35 frames. It is evident that the depth of field (DOF) is no, and at 50x magnification it will be even less.
rod ballpoint pen. Pleased processing traces on the seemingly completely smooth metal.
The cut slices of mandarin.
And finally - a bug found on the windowsill. He was less than the size of the coffee granules, so that entirely fit in the frame with the maximum available magnification. It turned out that he was fluffy!
