    recommendations for 4x5 dev w/rodinal?

    I just started playing with my dad's speedgrafic. I'd like to try using rodinal with efke. i'm starting with tray developing small quantities. I read that you shouldn't use an acid stop with this film. so I need suggestions for two things... rodinal & ... what are the options for non acid stop baths?

    Thanks! any suggestions would be great!

    I've done lots of films in Rodinal recently - all ISO100 films seem to be fair in Rodinal 1+25 for 10 minutes.

    I never use stop bath at all, just water.

    Hi: you can use water. If you want, use a deeper tray than you use for dev and fix, and agitate the film for a minute or so just as you'd agitate in the dev and fix.
    To be extra safe, you could clamp a hose to the tray and run the water at a low flow rate to get a continual change of water.
    I haven't used acid stop on film since the late '70's, when I read that Judy Dater used a water stop (in "Darkroom" or "Darkroom 2," I forget which.) It's a lot easier on film.
    Which efke? Rodinal is great; so is HC110 in dilutions weaker than dilution B. Welcome to 4X5!!

    I too use water for a stop bath. Since I use TF-4 fixer, which according to the manufacturer should not be used with an acid stop, with all films and I've never had any problems.

    I use a water stop bath for Efke and Classic Pan films.

    I stick to 1+100 dilutions of Rodinal, and develop my 9x12cm and 4x5" film in a tank (120 Gepe tank) either one at a time by slipping the film in emulsion side in, or two or more sheets using rubber bands around the film (taco method).

    This way I can do most of the process in daylight.

    My experience with Efke is that PL100 (Efke 4x5 film, 100 ASA) turns out well in Rodinal 1+50 at 10 minutes max., so Rodinal 1+25 for 10 minutes for Efke 100 would be way too much. YMMW....

    I also do Efke R100 (120 film) in Rodinal 1+50 for 10 minutes.

    I like a higher contrast than most - the "mesocontrast" which gives the prints life and is difficult to manipulate in printing. Then I burn and dodge in printing to get the macrocontrast right.

    But that's just my way of getting the results I like!

    Use water or nothing. I skip that step. With Rodinal being so dilute, it probably won`t make much difference if you skip it or not.

    I use alkaline fix, so an acid stop is out for sure.

    Thanks all for your suggestions. I haven't decided which Efke, just that I like the comments I've heard about it from Apug members & from J&C and how it's great combined with Rodinal. I found some 20 year old Sodium Sulphite in my inheritance along with some crystalized rodinal. I was wondering if the SS was an alternative for non-acid stop baths? Or is that another topic?

    Thanks again...

    I just recently tried EFKE25 and APX100 in Rodinal. Both new film and developer to me (after TMY/TmaxRS combo for several years). There are 2 things: Using Rodinal and EFKE Film (120). Using Rodinal I found: Agitation is very important, thats why we see times from 7 to 17mins @20C. I follow Rodinal leaflet, and it says, first minute cont agitation, then 1x (!!!) / 30 secs. It really felt strange, just inverting the tank 1x after being used to 4-5x/30secs. But it really works and speed is also acurate according to Agfa (25 for EFKE25 and 100 for APX100, both in 120 though). For EFKE25 I use 1+100 (18mins) and for APX 1+50 (17mins). I used Pentax digital spotmeter for metering (somehow didnt work when using Gossen LunaProF)
    Second: Dev 4x5". After getting frustrated by doing it in the dark in trays and still getting scratches, I finally used Jobo2500 tank (6sheets and 1500ml dev) and agitating by inverting like roll film. No problem so far, just using more developer than tray/rotation.
    Just my USD0.02
