Digital BW, The Print

An alternative to that is to open an RGB image, convert to grayscale and
take a snap shot. Undo the conversion and you will notice that your snap
shot is still there. Now do your conversion using channel mixer and convert
to grayscale. Take a snap shot. You can click on the state of each snap shot
either save to file if you prefer one to the other or paint with a history
brush to correct the interpretation of a particular colored area or contrast
range that you created within that conversion. You have all the conversions
on the same document and if you like any one or all for later, save each
one. 

 

The changes that you make to the file using channel mixer will stay and be
processed by the conversion setting. If you desaturate a scene, it will look
different when converted to grayscale as well. I think you may be confused
as to what is happening along the end path to grayscale. Look at it like
this, once you take an exposure with traditional B&W film using a colored
filter you cannot undo the effect through processing; i.e. a red filer to
darken a sky.

Hello Art,

These are good questions but you don't need to ask someone else for
the answers. Take 3 minutes and do a test and find out first hand. 
Open a color image, convert to mode->grayscale, and save it to a new
filename.

Then reopen the color image, go to channel mixer, monochrome + twiddle
some settings, then convert to mode->grayscale (you'll see whether or
not it changes your settings) and save it to another new filename. 
Then compare the two BW versions and you'll have your
answer. 

Regards,
Clayton
