Here is an idea for a Kickstarter boutique business, as follows: make “Kickloads” with 400 Speed 4x5 black and white film like Ilford HP5. These would be film in sleeves with end clips that would fit into all those existing Fuji Quickload and Kodak Readyload holders that we have. $60 for a box of 20

Another idea is a 4x5 Polaroid back that will accept the current Polaroid (formerly Impossible) instant film in “One-Step” or “SX-70” type film. It would not show the whole 4x5 frame but would allow an smaller proof positive check for key shots. Could be a hacked One-Step -type camera mechanism in an international Graflok size. $185 for the back.
