Ya I couldn't see them that well either just lookin in the cab.
The macro setting on the camera at a high res then crop out a small section of the pic and resise it larger.
Theres nothing to it man, you trim the buds before hanging and ya get most of them off.
Whats left there will leave as the bud drys looking for a live plant.
Its a yield thing really, If you let them suck on your grow all flower I would say you would end up with nothing. If you fight them you lose half, If you get good at fighting them you lose 25% but I think if you do the right prevention you could lose zero.
I have smoked bud from the same grow, some had mites, some didn't. I couldn't tell the difference in the smoke doing it this way.
