Hello All,
I found this rather old post ((there was a url link here which no longer exists)) by Donald Miller describing an update to the PPPD that he originally formulated. Over the years, I have used on occasion a variation of the original formula posted by JB Harlin on his website. I would like to try the variation Don posted in the aforementioned link, but I'm a little confused. Therefore, requesting help from any APUG member who uses this particular variation:
The formula, as listed in Don's 1-3-2006 post, leads me to believe that all chemicals are mixed (in order, of course) into one solution. The original formulas (as posted on Unblinking Eye) and the Harlin variation mix a solution A and a separate solution B which consists of the sodium carbonate. This A/B solution is then mixed 1:1 for use. No citric acid is used in the Harlin variation. Following Don's updated formula, is it really mixed as a single solution or still two solutions? If A/B, which solution does the citric acid go into? Also, it seems that emergence time is pretty fast when compared to other paper developers such as Dektol. Is normal development time still 2 mins?
Thank you for any help provided.
Best regards,
Alan
