Here's an awesome tip I learned from Mossy that I used to do before I got my loupe.
Turn all the lights off in the room so it is completely dark and take a picture of your lady with the flash on. The reflection off the trichomes - or lack thereof - will give you an idea what they look like. The more shiny, flashy reflection you get back off the buds, the clearer the trichomes are. The less reflection you get, the more your trichs are milked up inside.
If you have trouble getting a focused picture, then just get your focus set up with lights on so that when you turn the lights off, you know your lady will be in the ideal range of focus.
