I got my hands on an old argyle 20 x 24 process camera and stand. I made a 8 x 20 film holder out of two old 8 x 10 film holders, and the dark slide out of 26 ga. sheet metal.
I had to make a complete back to hold the film holder, because these have the vacuum backs on them, and to tell the truth I really don't know how they work?
I've been shooting 8 x 10 for a couple of years now, But the image I saw on the ground glass was truly awesome, this was before I put my substitute 8 x 20 back in.
I starting shooting with a 4 x5 speed graflex which I still have, it's amazing how far this addiction will take you.
I'm ready to go make a pin hole camera out of semi-trailer
Who's with me?
