[pct-l] Photos & Captions

[Michael Donnay]

After many hikes on the trail, I have finished with a collection of thousands of photos.  But years later, I have little way of knowing what is in each photo.  At least they are in sequential order from Campo to Manning.
I wish I had somehow recorded the name of the peak, pass, range, valley, river, lake, meadow, hiker, etc in each photo.  Has anyone figured out an easy way of doing this?  Does it require some special camera equipment?
Thanks,Mike
