Velvia 4×5 tetenal E6 3 bath process, an alternative to sending your chromes to the lab.
This past week I have been trialing Tetenal’s 3 bath E6 process with 4×5 velvia. I must admit I had a little trepidation about undertaking a colour process. The last time I processed colour slide it was as a young teenager using my mother’s cement laundry troughs out on the back verandah. Back then it was the Kodak E4 process, and it required that I refog the film to a 500 watt light source after the initial development. I was processing Pacific 35mm slide film from my high school’s media department. The results were radical to say the least, blue and magenta colour casts and wildly contrasty images. Needless to say I loved it. But it’s not exactly a comforting result if you are processing your professional images that you have spent time, money and effort just traveling to locations to create them.
For years I was sending my chromes to Melbourne for processing, but I decided it was time to rethink how I wanted to process my 4×5 velvia. It was time to press my Jobo processor, which I use for all my black and white negatives, into doing some colour work for me. I started with a 1L Tetenal kit and put a few 120 velvia film tests through first to confirm my development times. I found a development time of 7.5 min a good starting point for velvia 50 ISO. To my surprise the film processing was remarkably consistent between batches and the information provided by Tetenal is a good starting point, and the process much simplified with the 3 step chemistry.
Overall I have been pleased with the results and I will be continuing with the Tetenal E6 during the year, using a one shot technique, processing 12 4×5 sheets at a time, with 48 sheets processed per litre of stock solution. I still have that 500 watt bayonet photo flood globe I used for E4 all those years ago. If you have a use for it let me know.
