Wow....where'd you go? What was the total cost in film and processing?
Well, can't speak for polyglot but I regularly come back from my trips (1-4 weeks) with 20-100 rolls. As 80% is B&W, I have no idea what the cost of processing is, although I know it's minimal since chemicals are cheap and I do all my own. Colour is usually slide and will set me back about $5 a roll here in japan. And getting back to the OP, I've had a similar backlog, although I can normally get back to it within the year.
My favorite thing is to go where I've never been. D. Arbus
