Who to buy RA-4 Chemicals from?

Discussion in 'Film and Processing' started by noel_meneses, Dec 14, 2006.

  1. I am having a bit of a hard time getting all the chemicals for ra-4 color
    processing from color negatives. I tried adorama but they dont have the
    developer starter, I tried bh but they only sell some of the parts in bulk
    order, amazon almost had them all except for the developer starter. As far as
    I know we will need

    RA Developer 5 liter
    RA Blix 5 liter
    RA Stabalizer 5 liter
    Developer Starter 5 liter

    or so the kodak customer service guy says. I am a low grade hobbiest and don't
    have any use for more than 1 gallon -5 liter quanities.

    Where do you all get your stuff? Should I develop with other than kodak? If so
    who has readily available chemicals for ra-4. Thanks for the input.
     
  2. Check with Photographers Formulary in Montana.
    1 (800) 922-5255 or 1 (406) 754-2891

  4. The developer starter will last forever. It will start quite a few litres of developer. You can
    have ANY Kodak dealer order it for you. I just use my local camera store. I need to assure
    you that it is not a chemical that "goes bad", ever. Don't worry about getting a larger
    quantity than you immediately need.

    I have often used the Agfa (brand) of RA-4 equivalent developer, as this seemed to have
    less tar buildup in my tabletop processor. I got the 20 litre developer kits, and since it is
    all liquid, easy to sub-divide into smaller quantities. Of course with Agfa chemistry, you
    had to use Agfa starter, which came in a gallon bottle. Agfa chemistry, I see is available
    again.

    For those who don't know about "starters". Most color developers (RA-4, E-6, C-41)
    come as "developer replenishers" and to make a working developer, you have to not only
    dilute the liquid concentrates with the appropriate amount of water, but add a "starter" to
    make a complete "working" developer. Over the years, when amateur interest was higher
    in these processes, various companies made small kits that contained complete
    developers, not requiring starters, just requiring diluting with water. But, now with the
    only viable market is professional and semi-professional, these simple kits are almost not
    available.

  5. Having just re-read your original post, I want to clarify a few more points over and above
    my reply above. RA-4 is the process for color prints. Color prints made from color
    negatives. You do not normally need "stabilizer" with this process. Stabilizer is used in
    large processing machines that do not wash the paper after the blix. If you are going to
    wash your prints for a couple of minutes before drying, you do not need stabilizer at all.

    It is unclear in your post whether you are going to process prints or negatives. If you want
    to process color negatives yourself, you need the chemicals for process C-41.

    Your bottle of developer starter will probably "start" many more litres than 5, but as stated
    above it does not "go bad". One bottle of starter will last you years, possibly.

  6. Use Kodak RA-RT developer replenisher in 10 liter (Part #841-5580) or in 5 liter kits. They may be divided down.

    You do not need a starter or stabilzer for paper. You will need a blix.

  7. But...with my Kodak RA developer replenisher, as well as my Agfa (RA equivalent)
    developer replenisher, the mixing instructions absolutely state to make "working solution"
    you must add starter to the properly diluted replenisher solutions. And, Kodak and Agfa
    and probably Fuji/Hunt make "starters" for this.

    Back when I was doing EP-2, I tried once to just use EP-2 replenisher mixed as a tank
    soluton, and it didn't work correctly at all, colors were all wrong. When I mixed up the
    "tank" solution adding the "starter" everything went fine. Has Kodak changed the
    formulation of the RA-4 replenishers in the last three years to not require starter to make
    developer?

    I know you don't need a "starter" for blix.

  8. I have been using the developer replenisher since the Supra line came out. The new papers are quite different than the EP2 and EP3 papers.

    Forget the starter and balance your entire process around the RART replenisher. I use 100F for 1' (or 45") and I use 2' at 68 degrees. That is one nice thing about the Kodak chemistry. It can be used at room temp.
