print c41/tcn 400 black and white HOW

if i print grayscale i get sepia tone same as if film printed by shop. I have read a lot of stuff on internet re print b&W but it all assumes you are starting with true b&W films. I have film developed to a CD, and it "registers" as RGB, but when try adjusting the channel mixer, etc and printing color = terrible. Printing it grayscale produces sepia. any help most appreciated.

Are you doing a simple color --> greyscale?

You can change the mode from RGB to Greyscale and it will discard any color information.

C41 processing is film that can be developed at your local color shop but when printed with B&W chemistry produces B&W. Kodak TCN 400 can be shot between 100 and 1000 pretty well so you only need one type of film traveling.

when the local lab prints it with their color processing, it prints b&W sepia. I want to print it B&W

If it "registers" it as RGB, that is probably what color mode it is saved in. What I am wondering is when you print in grayscale, are you selecting grayscale from the Print options? or are you converting it to grayscale in PS, then printing it, which shouldnt give you any sepia tone.

The Kodak TCN400 is called a chronogenic film. It is not true b/w. You cant get true B/W photos from a chronogenic film because its a C-41 process, which is color. THe prints like you found out are sepia. If you want to shoot b/w you would use TMAX or TRIX or ACROS, which are TRUE b/w films. To change the sepia tone, buy a filter patch for photoshop and youll be garenteed a filter that would make your sepia prints b/w.

Try Agfa Scala 200x. It is the only b/w transparency film ever made. The results are out of this world. Try pushing and pulling it as well to get even more dramatic slides. Then have prints made from your slides. Below are two links that have 2 slides that I had scanned made from Agfa Scala. The 1st is pushed 1 stop. The 2nd is pulled 1/2 a stop.

thanks guitar guy, I didn't know you could buy filters from PS

Yup.. Try searching the internet first for photoshop plug- ins. You can get extra fonts and filter. Probably can download 300-500 at a time for free.
