I heard about a Christmas photography meme via John who got it via its originator, Quietfish. Basically, you take a second every hour during Christmas to take a quick snapshot, to record what happens throughout your celebrations. You can post them immediately, or after the fact.
I’m going to try it, and I’m going to start now, because for me Christmas Eve is a significant part of Christmas (and also a very photogenic part, at times). I’ll probably share on Boxing Day… If you want to join in, let me know – and tell Quietfish, too.
