Tri-X - How much light do you need?
How much light would you say is needed to get a decent image out of (super 8 ) Tri-X? I have head that with Tri-X you can shoot in pretty dark situations, is this true? I will be seeing my first couple of rolls of it in a couple of weeks hopefully.

Hi Ed,
...depends on what you want. Less light = more grain. My best super 8 results have come from over exposing films by about one stop. If you want low natural looking light it is best to shoot a larger gauge. If super 8 and low light is a must, I suggest 7218 color negative (500T) then go to black and white in post. There is an art to going black and white with color negatives and I'm not an expert at it, but I do know that best results are acheived by first cranking up the red channels before going to greyscale..

Tri-X is actually quite good for low light (in 16mm, at least). I used it for a lengthy interior sequence lit only by a single fluorescent fixture (two bulbs, maybe 40w total). Of course, the fixture was about three feet from the main subject, but the lighting was still more than adequate. Stills:

Thanks for the replies. I have a roll of Tri-X I was going to have push processed, though I don't know how many stops. I shot outside with maybe 400 watts of light, and maybe 7 feet or so from the light. But, I made a very dumb (and embarrasing) mistake of underexposing the film a stop. My camera normally would overexpose by a stop so I think it just exposed normally at 160 ASA. So I wasnt sure how many stops if any would be the way to go for this situation. And also I just wanted to know for a future project how much light is usually needed for tri-x.
