skip_a Posted March 6, 2005 Share Posted March 6, 2005 I've searched for the answer to this, but I can't find it on PN oranywhere. I'm trying to figure out the minimum E6 solution amount perroll of Super 8mm film. Kodak says to use at least 250ml of each E6 solution per square footof film. Then they say 235ml per two 136-36 rolls. That doesn'tcompute, by my calculations. I measured a 36 exposure length of 35mm film. It was 5.25 feet long. 35mm is .11 feet x 5.25 feet = .58 square feet. So 250ml x .58 sq ft= 145ml, and two rolls is 1.16 sq feet x 250ml = 290ml. How did Kodakget 235ml for two rolls? It's clearly more than one square foot offilm, and the minimum for one square foot of film is 250ml. A roll of Super 8 film is 50 feet by 8mm = 50 feet by .0262 feet =1.31 sq ft, which means 1.31 x 250 ml = 327.5 ml of each E6 solutionper roll of Super 8 film. But is it really correct, given theunexpected recommendation for the 135-36 films? This question is somewhat academic. There are no Super 8 films thatare processed in E6 chemistry. Also, my movie film processing tankrequires 1.4 liters for two rolls of Super 8mm film, so my realminimum is 700ml per roll anyway. I'm just perplexed by the seeminglyinaccurate Kodak equivalents based on the stated 250ml per square footminimum. I suppose if I could manage to process a roll of Super 8 film in about300ml of E6 solution, that would be close enough for practicalpurposes.

krisheylen Posted March 6, 2005 Share Posted March 6, 2005 Your math is wrong: you didn't discount the sprocket holes. LOL :-) Link to comment Share on other sites More sharing options...
discpad Posted March 6, 2005 Share Posted March 6, 2005 Most all cinema film is developed in a roller transport or leader card processor anyway. Fuji Velvia is an E-6 cinematography film... Link to comment Share on other sites More sharing options...
