    Film development in paper developer

    Hi,

    I want to have nice big grain in my negatives. Consequently I want to try developing my 8x10 inch bw film in paper developer. I have a bottle of Tetenal Eukobrom and develop in a Jobo Expert drum 3005. I use film developers only once and would like to know how much developer per film sheet I need.

    My question is: Can I use the given capacity for paper on the bottle and use it for my film development.

    For Eukobrom it says 1 liter working solution (100ml developer + 900 ml water) for 5 square meter of paper. I calculate the following:
    8x10" –> 0,052 sqm –> 19,3 films per sqm
    100 ml Eukobrom for 5 sqm –> 20 ml for 1 sqm or
    approximately 1 ml per 8x10 inch Film.

    Is that completely off? Has anyone an idea.

    Thank you
    Johannes

    hi johannes

    using print developer won't necessarily give you "big grain"
    i never get big grain when i use ansco 130 for film ( 10+ years )
    and i know of people who use dektol ( 1:7 / 7mins &c ) and don't get
    big grain either ...

    i can't speak of the capacity with your developer+jobo
    since i use it in trays, 1-shot, or i replenish, but half/half ...

    good luck !

    good luck !

    I've tried dektol in the past with the resultant big grain. Times were extremely short fort the dilution I used (in and around 2-3 minutes I think). I used it one shot though.
    notch codes ? I only use one film...

    I've developed film in dektol and a mix of dektol+xtol. Dektol was a little contrastier than xtol.

    The quantity is way off. 1 ml of developer will not come close to covering the film. You need at least 200ml per sheet in that drum to get consistent results. You will get an increase in contrast, and some grain, but I cannot predict how large the clumps will be..

    What you indicate is that film needs 200 times more developer than paper or do you talk about the total amount of liquid in the drum?

    The drum needs around 300 ml to 1000 ml of liquid to work properly. I was talking about the amount of concentrate. For xtol you need 100 ml concentrate per sheet. So if you work with 1+1 you need 200 ml liquid per sheet.

    For Eukobrom I find only the numbers for paper and they indicate that the capacity of the concentrate is 1 ml pure developer per 8x10 paper.

    I want to work with 1+9 dilution. I need an absolute minimum of 270 ml liquid in the drum (Jobo data). So basically my question is:
    Is 27 ml developer + 243 ml water enough for 5 sheets of bw film (enough capacity of developing agent not amount of liquid for even development, you can run the drum with 300 ml without problem if you have enough agent)? Because of the size I can't work with 10 ml of solution anyway. I want to work in "single shot style" - if possible. I just don't know whether you can use the capacity data for paper and apply it to film. The only thing I know is that film and paper contain approximately the same amount of silver per sqm (2-5 g).

    Best,
    Johannes

    Chime in if I'm wrong, but why not use a high ASA film, develop in 1+200 Rodinal?

    I've been told higher dilution gives a wee sharper image but at higher grain.

    Thought I'd suggest this & hope it helps you!
