This past summer I upgraded my scanner to one that can handle 4x5 film. I recently discovered that along with the ability to scan my 4x5's , it can also help me create substitute contact sheets for any 35mm film I shoot. These have been very helpful in determining what and what not to scan.
The below is a scan of negatives from Joel and Chelsie's wedding. Normally I only shoot digitally at weddings with a few sheets of 4x5 film thown in. At this wedding I shot a few rolls of 35mm to go along with the rest of what I shot.
