    Re: Longest Wet Plate Exposure Times

    The longest exposure I've made was something like 16 minutes outside. I didn't have any problems with drying which was a surprise. This was on a wet, mild day. I've done up to 8 minutes on a bright sunny day before.

    Re: Longest Wet Plate Exposure Times

    There is an account of Carleton Watkins doing hour-long exposures in the book "Carleton Watkins - Making the West American" by Tyler Green, though it seems Green got this information from some other source, and it is not related how this was possible. I don't have the book available at the moment. Perhaps it was some sort of dry collodion recipe?

    I would assume it was dry plate. Wet plate does indeed dry out as the ether evaporates.
