so im filming a short segment thats going to be projected in a theater on a screen about 20ft diagonal. im set on using 16mm (thats the system theyve got), but when i did tests, the picture wasnt grainy enough. its supposed to look like ol timey stock footage, so im trying to find ways of degrading the image. i plan to shoot on 16mm tri x, but can anyone recommend other lab processes or methods to grain it up?

The Tri-X Reversal (7266) *I think that is the number for it* is a fine grain stock. So there would, inherently be less grain. PlusX is even slower and less grain.
The Double-X (7222) might be more the film to look into. It is a 250D. So faster than the Tri-X which - if memory serves me - is a 160T. The Double-X would have more grain to it - since it is a faster speed film.
As to lab processes, I can't think of any off the top of my head. You might want to call a Kodak Engineer though.

Try pushing your film a stop or 2. (ISO 400-800/1600) or start out
with a higher ISO film. The higher the ISO the grainer it gets from my experience.

okay, so I could shoot doubleX, rate it at 250 ISO and push it a third. Sounds like a good start.

I'd say the doublex would be a good start. 250 is what she is rated anyways.
Let me know if there is a difference between that and the TriX. I am curious to know myself.

I projected triX, and it just wasn't hitting it. I'm hoping the double x will add something

Can anyone point me to where I can find sensitometry curves or at least tell me the dynamic range of double X negative? The kodak site is a tad cryptic.

I should have searched for that earlier for you. Kodak's website is near impossible to find anything on. The only way I can get through it is a Kodak sales rep walked me through the website when I first got into film.

Pushing it a stop or two will definitely give you more grain. The lab will do free clip tests for you as long as the clips aren't over a few seconds.

if you just want more grain and are doing a DI, do it in post. But, if you want to be a man about it and do it in camera, I'd jsut go with using a slower stock and compensating with ND filters.

you mean a faster stock... :laugh:

LAY OFF ME I'M WORKING! sorta.
yes i did mean a faster stock.

im considering now shooting tri x 8mm, and bowing up to 16mm for the print. I'm asking the lab about costs.

You might try Super 8 stock, which comes in all flavors and is loaded with grain, especially if you push it. Pro8mm.com has a full range of stocks with processing deals. Question? Are you actually planning to project film or a dvd with the film on it?

The 8mm is going to have insane deep DoF. I'd shoot 16mm and underexpose by one stop, then push it one stop. If you are shooting Kodak b&w stock, you will see tremendous increase in grain.
(7222 & 7231)
Shooting color is all dandy, but the grain wont be as dramatic when pushed. Perhaps try a stop and a half under and push the equivalent.
