I don't know if photographs should make you act, but they should stir something. A lot of the recent pictures from Kiev did just that, but at times it was just too spectacular; the smoke and the ash and the shields were too reminiscent of a volcano going off. They were distant and cold.
The massacre of protestors (and there's a little undercurrent of propaganda going on there. Always remember that Stalin allied himself with the Nazis. No getting away from that once you get down to Nazi name-calling) changed all that.
There has been smart photography on Ukraine by Anastasia Taylor-Lind and Donald Weber among others, but I also like Paolo Ciregia's take on events. He's a young Italian photographer who is still in Ukraine somewhere, but his pictures have a poetic ebb and flow to them that realises something of the spiritual depth of emotion involved in events. With his focus on isolated individuals (and this selection accentuates that) there seems to be a kind of determined calm in the maelstrom of events.
