    I found one error in the latest edition so far. Formula #57 WD2H+ (John Wimberley). No preservative in solution`A` on page 236.

    Yes, Elon is Kodak's trade name for Metol. There are various other trade names for Metol

    No Way! I'm one of a few who process single tray using one

    Beer's and Adams' contrast control developers have low
    and high contrast components. The high contrast components
    contain the hydroquinone along with sodium carbonate and
    sulfite and a little potassium bromide. That last possibly
    optional.

    Beer's 1 is equivalent to Ansco 120 and likely Selectol Soft.
    Seven blends are specified; Beer's 1 has only the metol portion.
    Beer's 7 has little of the metol but much of the hydroquinone
    portion. IMO, 7 blends are more than enough to fine tune
    contrast. Blends 1-3-5, and 7 may do for most purposes.
    Steve Anchell rates 7 a bit more contrasty than Dektol.

    Adams' 130 works the same way although no exact amounts
    are specified. With Adams' you'll have that Glycin touch. One
    big difference; while the portions of both A and B vary with
    Beer's, Adams' Ansco 130 varies the B portion only. That
    is, to increase contrast he mixed in some B portion
    until he got it just right. Dan

    Good eyes, Keith. Sodium bisulfite is what's missing. I looked up the amount, but the formula has changed a bit in the last few years and the original amount was 5g, but the new version uses different amounts of chems.

    I reported the error Jim to Steve Anchell but no reply yet.

    I'm glad Mr. Anchell is right on top of it!

    Anyway, according to a handout I have from John Wimberley, it should say "sodium bisulfite 20.0 g" It goes in the list of ingredients right after the metol.

    I'd suggest taking a pinch of bisulfite and dissolve it first before adding the metol.

    This is an authentic Canadian Formula of Kodak's D-52.
    It is similar to Dektol, but has a different balance of metol and HQ , for a more useful contrast.

    I've only used it for 40 years, but it shows promise.

    It does everything Dektol will do, but you won't have to use the 2x4.
    Don't tell Les.

    PM me for how you can easily use Bromide as a control.

    It's identical to D-52 except for the 12.5 g of Hydroquinone instead of 12 g. It's similar to Selectol, rather than Dektol so is slightly softer working.

    Here is an official Kodak formula for D-52, Photo Almanac, Anchell 1st Ed.

    Water 500 ml 500 ml 500 ml
    Elon 1.5 g 1.5 g 1.5 g
    Sodium Sulfite (anh) 22.5 g 22.5 g 21.2 g
    HQ 6 g 6.5 g 6.0 g
    Sodium Carbonate (monohydrate) 17g 15.0 g 17.0 g
    Potassium Bromide 1.5 g 1.5 g 1.5 g

    Water to 1 liter in each case.

    I also have the Handbook of Chemistry and Physics version and I'm sure some others, but they are basically all in the range of the above.

    The formatting of the above, while neat in the original, turns into crap when posted. Sorry! I've tried to patch it as best as possible but nothing helps.

    Yes. And we should note, that we aren't talking about Selectol Soft !!!!!

    Softer working, but fully capable of printing a proper #2 negative on #2 paper with full Dmax blacks. It is just a lot easier to control than Dektol.

    And if you can make D-72, you can make this.
