I seriously enjoy both saggy and soggy curves and the observation that Edwal 12 is a RELENTLESS developer. This is what it is known for. I was lead to believe and expect that if you wished to expand a rather flat scene, Edwal 12 was right for the job. True, it seems to be. However, lest it be casually denied that one can contract with E12, take a look at the example below. Ilford delta 3200. Edwal 12. I'd look into E10 but I'm more interested right now in shooting what I have working for me, and E12 definitely is giving me what I'm looking for right now. As a veteran MCM 100 user, I am not put off by PPD. Yes, I know it causes cancer in laboratory animals in the state of California.
By the way, I also started with Germain's version, and it, too, is great. Not significantly different from Lowe's version. I suspect that you could use Lowe's recommendation about replenishment for it as well. You could also use it one shot as Lowe suggests for E12, dilute 1:9 and develop twice as long.
If by chance the example doesn't load (I don't see it) here's the url:
