Abby Bader April 8, 2017 Share April 8, 2017 The values below are the channel combinations used on classic black and white films stocks. You could try to input the numbers in the monochrome mixer and see if the response is close to your perception of how it should look like.

cameronrad April 11, 2017 Share April 11, 2017 I think there's some extra digits to those numbers? I believe these are the numbers you're referencing: http://www.markushartel.com/blog/learn-from-markus/channel-mixer-settings 3 Link to comment Share on other sites

I believe the original source of these numbers was actually this blog post http://www.prime-junta.net/pont/How_to/100_Curves_and_Films/_Curves_and_films.html from years ago. Which may have actually grabbed those numbers from some old photo forums like https://luminous-landscape.com/bw-better/ or http://www.russellbrown.com/tips_tech.html Edited April 13, 2017 by cameronrad 1 Link to comment Share on other sites
Abby Bader April 18, 2017 Author Share April 18, 2017 This reminds me of shooting with my life love Fuji X100 compact camera. Tri-X inspired B/W mode and the Bayer sensor got an amazing analogue feel that outbeat all the newer X-trans sensor on today cameras. Love black and white. Link to comment Share on other sites
