Hi all - Just purchased my first large format 4x5 camera. Very excited to start shooting with it. I'm looking for a Fuji PA-145 holder for the smaller 3.25"X4.25" fuji instant films. I believe the Polaroid 405 holder will work as well. Hoping to get some quick feedback on what I am doing (wrong) with the camera movements. The seller is including a polaroid holder for the full sized 45 instant films, but they seem to be very rare and expensive.
