Keep taking pics every time you are in the hives and then review them later in the evening. I used to take a picture of every frame–wide and some close ups. I still try to do this as often as possible. It's amazing how much additional info I derive from the pics. Mites, eggs, amount of pollen etc. The more I looked at the pics the more I learned and it taught me what to look for when I was actually in the hive.
Nice shot...
