Re: [Digital BW] Converting color images to grayscale

2002-09-07 by david_bookbinder@sprynet.com

In Photoshop you can use the Channel Mixer to refine your conversion 
to B & W. I know this only through hearsay, though, as I use 
Picture Window Pro, which lets you apply filters to the color 
image much as you might apply filters to the camera lens or enlarger 
lens. This seems more intuitive to me. 

In either program, you can also just extract one channel and 
see if it produces a more pleasing B&W image than changing the 
mode. The idea behind all of these different methods is that 
different images will look better in B&W if you emphasize one 
R, G, or B channel in a way different than the Image | Mode command 
does.

That's about all I know, as most of my work is now in color so 
I haven't done any recent experimenting or searching. I know 
that there are also Photoshop plug-ins which claim to do a better 
job than native Photoshop, but haven't used them.

I've always used the Photoshop Image->Mode command when I needed 
to 
convert a color image to grayscale, but I've seen various references 

to other software used for this purpose.  I'd appreciate any 

information on what software I might consider as an alternative 
to 
Photoshop for this purpose and also any technical info on what 
the 
software is doing (whether Photoshop or other) when an image 
is 
converted from color to grayscale.  Also, any thoughts on how 
to 
evaluate Photoshop vs the alternatives with respect to the conversion 

process and resulting image.  In other words, in what way would 
my 
grayscale images be better if I used a program other than Photoshop 
6 
do to the conversion?
