As of today, according to my post about my 365 Photo Project, it has been exactly a year, so it seems appropriate to have some sort of follow up.
I didn't have a structured system, and I was not as disciplined as I had hoped. I fell short of the goal with 307 out of 365. In the beginning I started hashtagging #day1, #day2, etc., but it wasn't long after I decided to drop the hashtag. It was much more liberating to just use #fordtographe365, even if I didn't follow through with that either.
I like to think it was the attempt that counts, and I haven't stopped taking photos. If you're looking for an end-of-the-year round up type app, I would suggest the 2016 My Best Nine. It gives a good summary of your nine best photos on Instagram, along with likes and number of posts.
