this is in fact 3 layer double)) two layers by me and one by @katya-leontyeva. first time i shot this roll (about a year ago, in October 2009), but i found out, that the batteries in my lca were down.. so the shutter didn't open... but before that, i sent the roll to Katya. So she shot her layer and sent the film back to me and i shot it one more time (this September). Imagine how surprised was i, when i received this roll from the lab and saw that somehow the shutter did open a year ago too...)))
