I took several 4x5 pictures this week using TMax readyloads in a Polaroid 545 holder. When I developed them 5 of 16 came out with no image. They were developed in the same tank with others which came out well and represented two different sessions in the darkroom. Would this be because they were not inserted with enough authority into the holder or is there another factor. There did not seem to be a problem during insertion, pulling the dark slide, or removing the packet from the holder.
Any answers or suggestions would be appreciated.
