You forgot Kodak HIE! ( infrared ) 100,100,-100 . Remember to run the saturation up before converting to BW with the Channel Mixer!

This is really good, I did not know about this!
So, can you take a BW converted by RGB channels and then add these values to the channel mixer?
Thanks

This is really interesting! I've never seen such a comprehensive compilation. How did you arrive at these settings, Patrick?
Gustavo, these are channel mixer settings to emulate various B&W emulsions with color images.

HUGH_thanks for the info, i will add it. I did know about it. I do my IR in another way in 4-5
step.

GUSTAVO_No! You have to work with a Color RGB.

EDWARD_I found many of these around the web, other was discover by trial and error, and as
a professional photoretoucher i develop a good eye to mimic some process. They are
probably not perfect but pretty close to reality.

I'm not understanding this...
Can you put it for a newbie?

In Photoshop, if you whant to do nice BW from a color picture in RGB mode, use channel
mixer in monochrome mode, enter those value at the appropriate place. could not be more
newbie than this : )
