Red and yellow filters with chromogenic film ???

[flamingo]

Will using a red or yellow filter on chromogenic film yield the same contrasting effect as using them on a true black & white film ?

Thanks

They will have a similar effect. If I remember correctly that was the answer Kodak gave me. You can querry them to double check.

Excellent. Thanks ! 😉

They have a similar but slightly stronger contrast effect with chromogenic b/w film than with conventional b/w film.

Same experience with BW400CN.

My experiance as well. As a rough estimate, I generally expect a filter to act as one level darker on BW400CN - a yellow will do about what an orange does for Tri-X.

I just had a roll of BW400CN pinholl done with a push-on 'cloud filter', either first or 2nd degree of yellow, and ran the film thru a 1-hour lab. They said 'they all came out fine'. I have them scanned right to CD in stead of prints so there's a degree of 'enlargement' for on-monitor viewing. I though tthe contrast was horrible. They looked fine with a 25 unit (%?) increase in contrast on Photoshop, but I was rather surprised how flat they looked.

I had been told this film would act just like regular b/w, but I think the comments of the group here suggest they have actually done it! I'm not sure the person who told me 'just like' ever tried it.

Are you experienced doing pinholes? If the film was underexposed, a filter would not have helped much and would have made things even worse if you forgot to take the filter factor into account in your exposure. A typical yellow filter might require a stop or so additional exposure.

Again, if BW400CN is underexposed it looks very dead (low contrast). I usually give such films 2/3 stop more exposure (i.e., rate it at 250). Among other things this makes it less likely that I'll underexpose it. Also, be sure to take the filter factor into account.
