I took these the other day — and immediately forgot where I put the SD card. As it turns out, I put it in a different camera. I think it was because it’s a big chip and there wasn’t much on it. The problem is, when I do that I end up with an odd collection of pictures from wherever I was when I was shooting. I spent a lot of the day sorting photographs.
At one point, I actually lost this month (August 2021) until I finally found it had moved and become a sub-folder under August 2020. Everything is back in place now. I found the pictures I was looking for as the card inside my birding camera. I would have hated losing the entire month.
