    I use a unicolor 8x10 photo-paper drum and unicolor roller, lets me develop 4 4x5 sheets at a time in around 300ml of chemistry.

    The constant agitation creates some very high contrast negatives, but I like my photos that way.

    Here's some info: http://www.largeformatphotography.info/unicolor/

    Another solution would be to try a two bath developer such as Thorntons two bath. 1500ml will happily develop 49 sheets before expiry. Also it is very inexpensive to make up and is easy to use. The formula is on the public domain so I am giving it here: -

    Solution A

    Water 1000ml
    Metol 9.5g
    Sodium Sulphite (anhydrous) 126g
    Water to 1500ml

    Solution B

    Water 1000ml
    Sodium Metaborate 18g
    Water to 1500ml

    Try 5 minutes in each solution with no rinse between solutions.

    I use replenished XTOL in the Jobo 3010 Expert Tank on a Jobo CPP 2 for up to 10 sheets at a time. Low chemistry cost and consistantly great results.

    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

    Marco, I use a Jobo tank and reel for 4x5 but I use it horizontally on a Jobo processor. This requires a minimum of 270mm of developer. I don't think that this can used properly without the processor. I develop 8x10 sheet film in an Expert Drum which can be easily rolled horizontally by hand and doesn't require a processor (I roll it in my darkroom sink).

    You can find second-hand Jobo CPE-2 processors for not much money and they are very economical to use, with regard to chemistry. If you can't find or can't afford one, tray development is also economical. I have NEVER been any good at tray development, however. I always scratch at least one negative. Some guys swear by it but they are obviously more careful than I.

    A slosher is probably the next economical way to go and when my CPE-2 dies, I will probably be looking into that.

    Good luck.

    As far as i understand the tray should be the more economical way to develop but at daylight.
    Paterson orbital is hard to find here.
    I guess i have to tray with tray....thanks anyway

    Lord, even an Italian ought to be able to google "film slosher", like I said to. If you had, the first choice given would have shown a picture of Steve Peterson's six negative slosher.

    The advantage of them is that the negatives stay untouched as you move them from tray to tray and you can process 1 to 6 negatives without having to stack them or handle them in any way. It is very useful for N+ or N- development, where you have only a small number of negatives to be developed differently and the process is relatively random for even development of the negative. You just agitate by a pumping up and down motion in the tray alternated with a repetitive motion similar to a priest's signing of the cross, using the "Dominus" motion several times and, then, skipping the Dominus bit and only doing the "Vobiscum" part several times.

    You can find an instructional video for the btzs tubes on YouTube. I watched that and then built my own version out of black ABS sewer pipe. Its the most consistent developing I've ever used.

    Marco,

    Trays or your Jobo tanks or whatever container you please replenishing is the most economical.

    Thanks a lot, and thanks for the Lord, I have really appreciated
