Personal biometrics at home? Microscope out of photocamera
Here we are. We connect 400 mm lens with a reversed 17mm lens. Fix a flashlight to the lens. It will play the role of the object table with light.
Your hair should look like this with this device.
After that I foresee the usual struggle between two religions - Canon and Nikon. Not sure who goes to win, but since Canon's lenses are cheaper, then Canon's owners have greater chances to have more material to boast.
