    D76 Dilution?

    I'm buying Kodak D76 and would like to know what is the recommended dilution for developing films like delta 100 and hp5+

    And just to make something clear in my mind complete this sentence:
    The more diluted the developer.....


    And, btw, is a pre-wash necessary?

    I like it diluted with an equal part of water for both these films. Follow the directions that Ilford gives for ID-11, and you're good to go.

    The more diluted the developer..... the more water you add

    Personally I'd use it full strength and replenish it. That's what we did for years in commercial use and I do the same now with Xtol, once ripened you have a far better developer.

    When I tried ID11 (the same as D76 I believe) at 1+3 as opposed to 1+1 with HP5+ I got noticably more sharpness with hardly any increase in grain. I wouldnt go back to 1+1 for 35mm, where I want all the sharpness I can get.

    Used replenished ID-11/D76 gives quite similar results once seasoned to the same developer used 1+3 in terms of sharpness, finer garin but the main difference is no marked compression of tones.

    I'm quite sure D-76 will work just fine at 1:7. I've worked with
    D-23 at that dilution and like the results. D-76 and D-23 are
    similar in their working.

    At 1:7 D-76 development times are off the charts. I suggest
    16 minutes for starts with some agitation every other minute.
    With D-23 my solution volume runs 500ml. Dan

    At any dilution, and especially when you go greater than 1:1 you need to make sure you have sufficient stock solution in the mix. According to Kodak the minimum volume is 250 ml per 36 exp roll.

    I've developed with 160ml of stock (diluted 1+1) and the negatives were fine. I guess these are very pessimistic figures that any manufacturer would suggest.

    Dear Fellipe,

    When using a new film, I like to bracket around "box speed" and develop using the recommendations on the manufacturer's data sheet.

    Dear Fellipe,

    I use 1+1 150ml D76+150ml water
    example 150ml D76@22 °C + 150ml water @18°C = 300ml developer

    well that's my trick
