Seneca 4x5 - how should I use it?
My friend's dad bought a Seneca 4x5 from around 1900-1910 at a barn sale in the 70s. It is in excellent condition, including the bellows and lens. The image appears perfectly on the ground glass. The thing is, I have no idea how to use it. It's meant to expose glass plates, so something thin like film wouldn't be focused properly unless it was mounted on something thick in the film holder. Should I use cardboard and film or just bite the bullet and make some glass plates?
