    If anybody switches to this or who already does it, has or comes up with times for emulsion/speed combo's not already present, I'll be pleased to add them to the page.

    This is pretty amazing. I decided upon 1:50 just last month. First because the time for AristaEDU-Ultra 100 is so short in 'B' that it's not recommended (and kinda short for PanF+, too) Secondly to make the math simpler for 1/2 litre & 1 litre, and lastly for economy.

    So I'm having good results with:

    AristaEDU-Ultra 100, rated at 100: 20C, 6.5 minutes [half a dozen rolls]
    Ilford PanF+, rated at 50: 20C, 5.5 minutes [about a dozen rolls]

    Who knew there could be such a broad opinion base as to what is simple? 1:50. 1:37. 15:1000 all are just starting points on the way to seeing what works for each individual.

    If it takes me a half an hour to explain dilution ratios, I probably need to work a little on my teaching skills.

    In the interest of KISS, when I took 1 oz. of HC110 goop, and added it to 31 oz. of water, I got one quart of useable film developer.

    So, if I choose to go 1:50, and have a tank that holds 500 ml of solution, and I wish to fill the tank, how much goop do I use and how much water?

    John -- you would need 10 ml of HC-110 "goop" and 490 ml of water.

    Which technically is 1:49, not 1:50, but the difference surely wouldn't matter.

    Matt,
    Yeh, that's what I figured. 1:49. 1:50, as we say hereabouts "Close enough for gummint work."

    Well, lets see....
    Take the normal Hc110 from-concentrate-to-stock-to-working dilutions complete from a working dilution (1:3) that is then mixed to give A-(1:3)-B-(1:7)-C-(1:4)-D-(1:9)-E-(1:11)-or F-(1:19) or you could direct dilute for A-(1:15) -B-(1:31)-C-(1:19)-D-(1:39) E-(1:47)-F-(1:79)-G-(1:119)or H-(1:63) with eight possible choices and eight possible times for one single emulsion and film speed and then run it by somebody who is completely new to developing and just grasping the concept of dilutions, answer their questions until they understand, and get back to me.

    Or you could say "1:50 for 8 minutes, and we'll look at your exposures".

    I guess I'd rather have them shooting and developing, over needing to unzip in order to show off my big brain cell.

    But hey, whatever floats your boat, man.

    Q: is this the argument room?
    A: no, this is the verbal abuse room. the argument room is two doors down.... and take that yellow goopy shit with you...



    Oh...Jason, Thanks for putting up the informative page. I sincerely appreciate the effort and agree it's high time for a simple introduction to the magical yellow syrup. Well done.

    I'm not sure that I'm ready for "simplification", besides, who are you? Your the guy who left us hanging for video part three, the Polaroid print!

    Guilty as charged. (I guess it's not like Who Shot JR?) I'll get that up this week.

    And that was good one, Art.
