I expose Delta 100 at ISO 50 and develop in Xtol at 68 degrees for 6-1/2 minutes. Incredible tonal range. I expose Delta 400 at ISO 200 and 3200 at 1600. I have not used any other b&w films or developers for many months. Also, I have not used the care that you are using in the storage of Xtol. I use distilled water only and I store in plastic. I have never had a problem. My best friend is a pharmacist and I will call him to save me some empty one gallon amber glass bottles. Thanks Bob << Delta 100 exposed at 200 and devloped in 125 ml Xtol + 125 ml water @ 20°/68° for 14 minutes with agitation 10 secs every minute is in my opinion the best combo in the medium speed range. >>
