I think Pyro has HC110 beat on shelf life. I've had bad luck with any liquid developers other than Rodinal and PMK Pyro. The most disasterous one has been Paterson FX50, their ascorbic acid developer. TRI-X negs shot at 400 look like they were shot at 6400.

I have heard that some like to use very small bottles to transfer the stock solution into and then just open one at a time. I learned to develop my own film with HC110 and it does give nice results. Safer than pyro, too. But I just love those beautiful negs pyro gives me! - Paul > > --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org - Online, searchable archives are available at //www.freelists.org/archives/rollei_list --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org - Online, searchable archives are available at //www.freelists.org/archives/rollei_list
