Hi there, I am looking to get started with lf photography. One of the reasons that I want to make the move to lf is to be able to print high resolution large prints (somewhere around 40"x50", maybe larger). I already have an area in my house designated for a darkroom, and will have the room to print at this size assuming one thing...I can find the right paper. What kind of paper do other people use to print around these sizes? Am I mistaken, would I have to have it printed for me for this size?

Sorry for the newbie question and thanks in advance,
Evan
