Their stated 6-12 month turnaround time (due to batching) and the cost make them the court of last resort. I have some chemicals and don?t mind getting my hands wet and stinky. ?howard > On Jun 20, 2018, at 11:50, John McMaster <john at mcmaster.co.uk> wrote: > > Just spend $42.50 and keep your hands clean? > > http://www.rockymountainfilm.com/e4.htm > > > > -----Original Message----- > From: LUG [mailto:lug-bounces+john=mcmaster.co.uk at leica-users.org] On > Behalf Of Howard L Ritter Jr > Sent: 20 June 2018 16:43 > To: Leica Users Group > Subject: Re: [Leica] Developing E-4 Ektachrome at home > > I?ve read that E-4 and E-6 processes are very different, and that E-4 film > will be ruined by E-6 processing.
