In order to get the kind of clarity that you see in his videos, you have to run the footage through a levels filter (I certainly don't get that level of clarity throuh my badass $300 Linfoln Viking). This type of filter essentially compresses areas of brightness or darkness within an image and brings out more (or less) clarity within that image depending on how it is adjusted. Normal .jpg images are 8 bits per channel images and if you run a levels filter on them you get all kinds of horrible artifacts that make the image quality even worse (noisy). Simply stepping up to an image format which supports 10 bits per channel is helpful in eliminating some of these artifacts due to image processing but, for real quality adjustments - 16 bits per channel is the lower limit required for artifact elimination (at least as far as your eyes are concerned).
I still see plenty of artifacts in his videos but not as many as I would expect from 8 bpc imaging. My suspicion is that he's either using an expanded color format which supports 10 bpc or that he has his camera's autodarkening lense dialed as dark as it will go and all other ambient light is eliminated from the back side with a heavy cloth or box of some sort. You want to deal with the least ammount of light pollution as possible where imaging is concerned. There is always plenty of information in shadows which you can't see until you adjust the image through an image filter but once you blow out the highlights (light saturation) you can never recover from it.
