Here is one taken on 3-1/4 x 4-1/4, f/16 1/50th sec on Efke PL-100 processed D-76 1:1. The lens is the standard Graflex Ektar original and is not the best, especially at the edges, but the group picture came out ok. Considering that it was made with a 70-year-old Speedgraphic I can cut some slack to the image. For larger groups I think 4x5 is preferable, but I didn't want to haul the larger camera to this reunion. There are better emulsions too, but not in 3x4 size. The standard lens is ok for such pictures but you will have to be farther back from the group and you will no doubt be using the image edges as well.
