About Photographers' Formulary

Yes, it *is* long lasting


from Salem, VA  -  Photo Enthusiast

The storage life of the mixed developer is crazy long, provided it's stored in a mostly-full airtight container. Even the working strength dilution lasts and can be re-used. I mixed my first batch of stock solution some 4 months ago and stored in air-tight bottles it remains as potent as the day I mixed it. No change of color, no loss of strength. Not only that, the quart of 1:1 working strength solution I mixed at the same time has over 70 8x10 prints through it and shows no sign of quitting. I've added just over a pint of fresh working solution in total, a bit here and there as I needed to, replacing solution carried out of the tray with developed sheets, so I'm effectively replenishing the developer as I use it. What *will* kill this developer is if you wait to too long to mix it. The Glycin has a poor shelf life in the powder form. Get it mixed ASAP after receiving the kit or your soup may be stale before you ever get to use it. Results are beautiful, too, though I can't make any direct comparision to other developers as it's the only one I've tried thus far. I'd give it 5 stars but for the fact that it /is/ quite a pain to mix up.

Long Shelf Life?


from Albany, NY  -  Semi-pro Photographer

I thought I'd try this stuff as it's touted as having a "long shelf life" and though I'm dedicated to film, I don't spend as much time in the darkroom as I used to. I followed the mixing instructions to the letter and this developer turned dark brown within a week and fell flat on its face soon after. Clearly the fastest failing developer of any kind I've ever used. Dektol laughs at this stuff!
