36 pictures per day. Every day you have to make exactly 36 frames. By the end of 7 days you will have 252 pictures. Now pick 10 of those to tell the story of your week and sit down and reflect on how that story makes you feel.
If you feel a bit more adventurous do the same, but only give yourself 36 frames per week.
(This assignment works best in weeks you don't have clients, but if you do, then 36 frames outside of paid work.)
