    I like MCC 110 from Adox. Undoubtedly works great with Adox Adotol. Also tested with Moersch Eco 4812(rich blacks) and Easy lith. So, it liths too.
  9. Re: What formula are you using for Divided D-23?

    I don't think dilution is possible with replenishment.
  10. Re: What formula are you using for Divided D-23?

    Yes, that's DK-25r. Can be replenished @22ml for a 80 sq.inch of film.

    It contains Metol 10g, Sodium Sulfite 100g and Balanced Alkali 20g. I presume BA is Sodium Metaborate.
  11. Re: What formula are you using for Divided D-23?

    Source for the formula: Darkroom Cookbook.

    Happily honing the composition and printing skills.
  12. Re: What formula are you using for Divided D-23?

    With 1l of Bath A, I can develop 24 rolls of 120 film.

    For me it is economical compare to D-23, which can only develop 4 rolls of 120 film @1:1.

    Never really look beyond the Divided D-23 where...
  13. Re: What formula are you using for Divided D-23?

    I personally use Divided D-23. Only reason is the economy when compared to D-23. They are almost identical and prints don't show any difference.

    Bath A - 1000ml
    Metol: 5g
    Sodium Sulfite: 100g

  16. Re: Incident metering: Hope my confusion will be resolved with this.

    I am still learning this method and the initial confusion was this discrepancy. So, I was thinking to sort this out first. Atleast for me it will take some more time to understand it very clearly.

    I see the magic of Pyro et al in your gallery.

    Okay, I will shoot without worrying much about the discrepancy. Finally I am relieved.

    Re: BTZS: Incident Readings in Flat Light

    My question is, do modern incident meters suffer from this discrepency too. The meter I own shows the measured values in EV and with that by turning dial give me shutter speed and f-stop combinations.
