pls help clear my doubt on push/pull techniques on B/W..

[behyx]

a very simple question: if i want a more contrasty image, should i push or pull the film?

i'm using Ilford Delta 400, so what ISO setting should i set on my camera to obtain the kind of result i want?

Anyone correct me if i am wrong...

Main purpose of Pushing/ Pulling:
1) Compensate for unexpected lighting
2) Pushing to achieve grains

To Increase contrast:
1) Filters
2) Develop at higher temps/ Concentration (the shorter the development time the higher the contrast)
3) Printing with higher contrast filters/papers
4) Developing Prints with developer at higher concentrations (same theory as film process)

to and extent, pushing ya film might help to increase the contrast.
but ya lose some ya gain some.
it differs from film character.
altering the developing process might be a better means other then to use filters that'll reduce the exposure or losing highlights and shadows from pushing.

delta on rodinal can work magic is ya're not afraid of the grains.
