    developing 4x5 sheet film

    i'm new to LF and i use at the moment a jobo tank/ reel to develop the films. The reel can keep up to 6 sheets and the tanks need 1.5 liter to develop (never mind if inside is one sheet or 6 sheets).
    I'm wandering if there is the possibility to develop using less solution. Most of the time I do not have 6 sheets to develop but only 2 or 4 and 1500 cc is really a lot.
    Thanks for your help

    not exactly sure how the jobo tanks work but every tank ive seen you need to fill it to capacity to evenly deelop the film, regardless of the amount of film. If you only have 1 or 2 sheets to develop maybe try tray processing.

    The point of the tank being full is that the 1 or 2 sheets you have in the tank need to be covered with developer at all times or else youll get very uneven development.

    If you have the typical 25xx Jobo tank with the 2509 reel, you can do manual rolling and only use ~300ml of developer. However, this would require you to keep rolling the tank for as long as the development process takes place.

    My Jobo 2000 tanks only need 1 litre per 6 sheet reel, I use Pyrocat HD which works out very economic even with that volume of dev.

    However you might be better off using a replenished developer, Xtol would be ideal as uniquely you replenish with fresh developer. There one or two recent threads on replenishing Xtol and it's what I did for about 20 years, very economic and consistent and the volume you need in the tank us unimportant (as long as the film is covered).

    Exactly. the quantity is regardless the amount of film and it's a lot.
    I'd like to use less chemical as possible (to save money). Is quite strange nobody has developed a way to process at light the films in a closed tray that can be agitated as well.
    The classical tray processing need to be operated in total dark. I love light....

    Have a look for a Paterson Orbital tray - With these, you can develop up to four sheets of 5x4 film with less than 100ml of chemicals (although I prefer to use 150-200ml).

    The Paterson Orbital had the option of a manual or a motorised base, but unfortunately, it is no longer in production.

    the bzts (sp?) tubes look like they use the least amount of dev. per sheet but i could be wrong. AND you can do a lot of the development in the daylight.

    I'm with Ian, Xtol replenished will solve the cost problem.

    17.5 ml per 4x5 sheet is what I plan on.

    I develop my 4x5 in a Nikor tank that can do 12 sheets and needs a full liter of developer to cover, still it's just 17.5ml per sheet that's "lost" the rest goes back into storage.

    Ciao Marco,

    I second the idea of tray developing. You will need total darkness and it does take a little practice, but once mastered, it is simple, low-tech, reliable and more flexible than any other technique. I can set up to develop 1 to as many sheets as I want, in batches of 6-8 and use as little as 250ml of chemistry at at time.

    There is a lot of information on this and other forums about tray developing. Give it a try.

    Best and good luck
