It’s an absolute pain, I’ve been running 10-15 cameras for over 15 years, when I first started using trail cameras they took traditional film.. imagine that.. After season when things settle down I go through all my photos and start deleting everything other than target bucks, or future target bucks, young deer with good potential, I then dump all those photos into albums labeled by the year or specific area taken. I have a separate iPad, with tons of storage dedicated just for my trail cam/hunting photos with nothing else on it so it’s not bogged down with other apps or non related hunting stuff, ONX and trail cam/hunting photos and video clips, that’s it. I generally label active camera sights with ONX a different color versus past sites so I remember where they all are to keep it straight, it gets confusing at times... I don’t need any other notes than the info saved on the picture, I give each camera a nickname of the area that only I understand.
