plus x and tri-x: what's the difference?

[Marco Van]

hi, i am fairly new to the super 8 filmmaking.

 

i want to know what's the difference between b/w stock plus x

and tri-x?

 

differences as in texture-wise, grain, exposure and look.

 

thanks.

The first major difference is speed, with Tri-X being faster. Next is flexibility, you can "push" Tri-X to higher speeds, at the cost of courser grain.

 

Now, the loss is that Tri-X is a corser grain structure than Plus-X, but with the new chemistry it's not too bad. Plus-X is a bit more contrasty as well. They give different looks for different jobs, pretty much.
