I bought a PhotoTherm SSK-4 few months ago, then I ordered the whole set of E6 processing chemicals (including all starters) from B&H and waited for few months. Finally I got all chemicals two weeks earlier. I called Kodak and talked to their chemists to make sure all mixing procedures are correct. Then I did the first run last night. I used two rolls of 120 slide. The result was a failure. The slides are very very dark. It is not transparent. Under normal room light, I can only see very dark images from the emulsion side. The other side is totally dark. I can't view anything using a slide viewing light box. I have to use a 150W light bulb to see the images. They appear to be seriously underexposed. Images have serious orange shift. I have no idea what went wrong 'cos I'm new in developing slide. I'm sure the slides are perfectly exposed 'cos I've been using these two cameras for years. After checking the SSK-4 technical manaul and Kodak E6 processing manual, I got this. Kodak's Info (I skip the water wash steps here. The machine did the washes perfectly) Kodak's Info SSK-4's Manual Steps Processing time (minutes) Processing time 1st Developer 6 6:30 Reversal Bath 2 3 Color Develop 6 4 Pre-Bleach 2 3 Bleach 6 8 Fixer 4 4 Final Rinse 1 2 Would it be because the time spent For Color Developer was not enough? Did that 2 minutes cause such huge difference? The slides aren't transparent? What went wrong? I tried to call PhotoTherm, but their technicial wasn't available. Can anyone help me understand more?
