These folks are way down there. The guy says the depth of field is 0.10 micron. What did he say? One tenth of a micron?

I didn't watch it again, but if I recall from the first time around he states the DOF twice in the video and contradicts himself. One time saying 1/10 of a mm (plausible at 100 microns) and one time 1/10 of a micron. I'm thinking the 100 micron figure is the acurate one.
Ink on paper will measure between 1 and maybe 6 microns. Let's say the average to be 3 microns. A member here showed a macro image of a portion of paper currency and stated it was stacked images. Really doubtful that it was done with the likes of what GigaPixel uses. So the 1/10 micron to me is plausible.
Capture Time:
How long it takes to capture the individual photographs. The average capture rate is approximately 900-1200 individual photographs per hour. The higher the resolution, higher the magnification, and smaller the size of the specimen, the greater the number of individual photographs needed.
