Filter for separation Carbon TRi Color
What is the best filters (Lee Filters or other) for colore separation RVB for Carbon Tri Color with a camera 5x7 inches with Ilford HP5+400 sheet 5x7 inches
What is the number reference of Filters for the Separation Color Red, Green and Blue
Thank you for your help and experience
I have more or less the same problem. I was looking into Lee filters. I think the Tricolour series is made for color separation (http://www.leefilters.com/index.php/...gory/tricolour ). Also wratten filters (29/61/47 or 25/58/47B) are often proposed. But it will take some time to wait for them on ebay….
My idea is to use my enlarger and generate separation of a c41 negative on normal panchromatic film with the red/green/blue filters. With a reversal process I want to get negatives again. I’m using this method at the moment to enlarge monochrome negatives for carbon print.
Since I would like to do four color carbon print I wonder how to generate the black separation.
The standard tri-color set is #25 (Red filter for Cyan Printer), #58 (Green Filter for Magenta Printer), and #47B (Blue Filter for Yellow Printer). For four color work,
#8 (Yellow Filter for Black Printer), along with 29/61/47 is recommended.
For Chris, thank you for the link to the Lee Filter

Thanks Charles for the information.
For the questions of Philippe:
Charles recommends 29/61/47 together with 8 (yellow) for four color printing (cyan, magenta, yellow, key/black).
For three color printing (cyan, magenta, yellow) 25/58/47B is the standard set. By the way the Lee tricolour set is also labeled by 25/58/47B. So I guess they are simply a copy of the original wratten standard tricolor set.
If Charles recommends 29/61/47, i prefer using directly but what is the reference of Lee Filter or other for the 29/61/47 recommanded by Charles, the Carbon Master of the Carbon Tri Color
These were only general filter recommendations. Direct separations (in camera exposures) or separations from TX's and/or color negatives each have specific filter requirements depending on film type and lighting conditions. See a Wratten Filter Guide such as http://www.karmalimbo.com/aro/pics/f...%20filters.pdf
for detailed info.
Thank you Charles for this informations
