Welcome Miss Marcy!
Last year I kept notes about my pictures...just a list of calendar dates and what the POTD (photo of the day) was, especially since I was using 3 cameras.
Then about once per week I would upload everything into a monthly folder, then copy the POTD into a P365 folder with subfolders for each month.
This year its a little easier since I am using Instagram, and iPhone keeps a separate photo album for Instagram, so all I have to do is look in this album. I still do the folder/copy stuff, I just no longer need to keep notes.
Some days I do more than 1 Instagram, but still not hard to pick from among the ones taken when it comes time to do my weekly page.
I've managed with this system for going on 3 years, including a month spent in Europe...here notes were really important, as I took a minimum of 100 photos per day, and choosing one was hard, but a fun problem to have
