Some really expired Kodak Ektachrome ESD film I tested in my 1990 LC-A. Shot it at 50iso instead of the box speed of 100 and it turned out really nice and bluey.
I managed to get some really expired (expired 1991!!!) Kodak Ektachrome ESD films. I loaded it into my 90’s Lomo LC-A (the film is in fact older than the camera!! hahaha) and brought it along for a lunch outing. While I was wary that its a good 20 years past its useful life, I decided to expose the films a stop down at iso 50. It proved to be a great idea and the photos turned out great (no doubt grainy). Underexposed photos look overly blue (but nice) while the nicely exposed ones look even better.
I read somewhere that film speed drops by a stop every ten years, and perhaps I should shoot this at iso25 the next time round!
This film gives a nice blue color shift when cross processed, compared to the green, yellow, red color shifts from the other slide films. Just right for me when I was getting sick of the Fuji Velvias, Sensias, 64T, Provias, etc.
You definitely gotta try this if you are able to find them!! (esp the really expired ones! =p )
