At the start of 2015 I started an Instagram project where I took a photo every time I went down to my local swimming baths. I started the project as way to make my visits more interesting and to give me an added incentive to keep going. I've continued it for a second year and ended up taking 111 photos in 2016.
I don't really have rules but I always take the photo on my iPhone (was 4s now 5s) with the iPhone camera and sometimes use Camera+ app if the contrast is difficult. I always take the photo from the same 50m stretch of the prom. If there are interesting clouds or light, I'll sometimes turn slightly east or west, but most photos are taken facing north across the Firth of Forth.
Above is just a small selection from the year, you can see the full grid, in chronological order, here.
