I'm posting my photos on Facebook, but I may share some here, too. I decided that if there's a photo I've already taken in the past, I can use it if it fits with the prompt; it doesn't have to be one I took in the past 24 hours. (For my Lent and Advent challenges, I even used some photos I didn't take - with attribution, of course - but I haven't 100% decided whether that's going to be OK for CY365.) However, part of the assignment I've set myself is that I must take at least one photo every day of the year.
My first photo for 2017; the prompt was "Happy New Year," and I posted the traditional New Year's food here in Haiti, pumpkin soup.
I think that in Lent and Advent, I'll use prompts similar to those I used this year (from Rethink Church and Alive Magazine), but I haven't decided if I'll double up and still use the CY365 prompts, or not.
So there you have it, my half-baked plan for the year, with more "I haven't decided" statements than definites. We'll see how it goes.
