r/largeformat

Over the last year I've been working on making and selling the Jagglé system of daylight developing cassettes. It is a system whereby the film holder for 1 sheet can be placed on top of our special developing tray to allow you to develop without needing to take the film out of the system in a darkroom for developing. You pull the second dark slide and the sheet falls into the developing tray.

Initially this was created to be part of a wider daylight enlarger system, with the purpose of being able to print without a darkroom setup.
I adapted it to large format however, and many people have created incredible projects this way. I am frankly astounded by the variety of applications people have found for the system. From roadtrips to boat rides to street portraits people have been using the system for all sorts of processes: RA-4 reversal, bnw-reversal, bnw negative etc. One of the interesting aspects in my opinion is that the system is quite modular. You can change the inserts in the film holder to swap between 4x5 film size and 4x6 (or 10x15) paper size for example

Now 1 year into selling the cassettes I am working on a V2 where I aim to improve the system in terms of robustness, both in terms of manufacturing and use; as well as expanding the range.

Currently I only have 4x5-graflok and 4x5 Graflex (slotted) for paper and film size.
On my wish list for release are:

• definitely 4x5 plates, many people have been asking for this since the beginning
  • In Graflok and Graflex mount, maybe more....?
• 5x7 film/paper/plates
• A contact printing version of the film holder

But I have also been send dimensional drawings for older style European 13x18 film holders, and I am reasonably confident I can make that work within the 5x7 line-up. And I have been asked for a solution for the Mamiya RB-67 and the Rolleiflex SL- style backs.

So I guess my question is; do you have other ideas of what I can do with this system? Is there something you would like to see?

So far on my LF journey I’ve shot Foma 100, Delta 100 and TXP 320. But I’ve actually never shot FP4 or HP5 in any format. I will definitely get some HP5 but what are the pros in Fp4 over D100. I’d love to lock down a stock or two. I know experimenting is the way but why would people on here go one way or the other. Kodak shits me with 10 packs and is too expensive so I’ll stick with Ilford for my B&W.

on 8X10 I have a 150mm, 300mm, 450mm and 600mm and want to sell two of them and I think Im going to just keep the 300 and 450. any thoughts from the community?

With say Kodak for example E100 and color negative films are pretty comparable in price.

Which do you choose and why?

I’ve never shot color on LF and would love to try. I shoot on 4x5

Okay, after visiting that 3D printed camera link & looking at the Bambu Lab A1 ($300 + accessories), I am seriously tempted to get into just making a 4x5 instead! Is this crazy talk?? I've never printed anything in my life, but I do consider myself on the more prosumer side of technical knowledge...ugh, and just the thought of building parts that I might want to try seems incredible! And why is there no mini technical field system that's 6x9 (Graflok 23) ?? Would love any input or suggestions from makers or buyers of printed parts. Thanks! ☝️🤓📈

EDIT: I love that there are so many here that both fans of the old analogue ways AND new technology enthusiasts! All of it is super exciting.
