I just started processing my E-6 Ektachrome 64T Super 8 films since...1974 ! back when I did B&W 4X and Tri-X Super 8.
I have a tank bought in Chicago that holds 1 x 50 feet film and needs 500ml of solutions for each baths.
I bought from Kodak a small kit for processing E-6 that makes 5 liters so I can do 10 rolls of film.
My first attemp was a disaster for 3 reasons: Underexposed film (I knew it), fogged film while loading in tank( no enough care, some
parasite light from under door in bathroom) and very bad drying method. But all the rest was well done and it showed.
2nd attemp was excellent: I shot a test film perfectly exposed with color charts and all: I loaded the film in total darkness,
mixed my chemicals in small 500ml bottles, brought the temp to 100F (ideal for E-6) by putting them in the kitchen sink
under constant thermometer monitoring, followed the exact times for each bath and TADAMMMM....After drying the film
completely in the spiral and rewinding it in a spool I enjoyed projecting it: fine grain, good contrast, exact colors, skin tones,
a few drying spots tough...But hey, home movies for a fraction of what a lab will charge you (6$ CAN per roll, beat that !).
And also, the magic of the whole process if you have the time....
