  Q. HELP! need more contrast
           Asked by Nicole Marcisz    (K=10214) on 8/16/2005
ok, I'm going to Utah in a few days and I'm bringing my old medium format rollieflex camera. Since I don't have a red filter for the lens and I'm going to shoot black and white. how can I get more contrast? I have Ilford delta 100 and 400 asa film. (it is 120 film). I was thinking that I could take the 400 and shoot it at 200 and then when I take it to get developed do I tell them to PUSH or PULL?
What would I do with the 100 film?
thanks for any advice you may share!!
cheers,
nicole

In order to get more contrast, you need to underexpose and overdevelop (relative to your normal procedure). That is, expose the film as if it had a higher ISO rating and then prolong the development time (push).

Or you could just expose normally and then make the prints using higher grade paper. That way you don't run the risk of losing detail in the shadows (due to underexposure) and/or the highlights (due to overdevelopment) in the negative.

I use Ilford Multigrade Filters when making the prints to achieve more contrast in my pictures. I got mine via ebay, low cost - great effect!

Normally, with a red filter you are trying to get more detail in the sky. At times a polarizer will help, but with a twin lens it is difficult (but not impossible) to use. The alternative is to shoot and process normally ( expose for the shadows, develop for the highlights) and in your printing, burn in the sky or dodge out the foreground.

try looking for compositions with the contrast to start with. If you squint at the shot you are trying to take you will get a better idea of the tones in it.

Also if you have a spot meter try and keep the values not to far apart that way you will have more chance of producing the contrast required in the darkroom


Or try the zone system!!!! but I am not going to try and explain that here!!!

Also for the dev times check out the contrast time charts on this PDF
