B&W Photos

A couple of questions about B&W. Dan Margulis has a chapter in his book about converting colour to b&w but says nothing about how to handle

b&w prints. The obvious thing to do is to scan them in greyscale and

the tonal range and print. However, is it better to scan as rgb and use

DM techniques to obtain a better result?

The second question relates to an rgb file in which I wish to use the

channel as my b&w final image. DM suggests discarding the other channels. How do you do this? Just drag them into the garbage can or is there a

refined method? Then, in what format should I store the result? Any advice will be appreciated.

Thanks,
Peter

A couple of questions about B&W. Dan Margulis has a chapter in his book about converting colour to b&w but says nothing about how to handle straight b&w prints. The obvious thing to do is to scan them in greyscale and adjust the tonal range and print. However, is it better to scan as rgb and use the DM techniques to obtain a better result?

The second question relates to an rgb file in which I wish to use the green channel as my b&w final image. DM suggests discarding the other channels. How do you do this? Just drag them into the garbage can or is there a more refined method? Then, in what format should I store the result? Any advice will be appreciated.

Sometimes scanning a b&w original in color can produce better results. If the picture has any stains or discoloration one channel may be cleaner than the others. Also the noise level in one channel may be lower if the scanner has some problems.
For converting color to gray, you can just discard the other channels to the trash.
You can store a single channel image as gray scale in .PSD or .TIF format.

An UK magazine called MONO issue 42 had a very detail description of scanning B&W and in issue 43 they were talking baout fine-tuning using Photogshop.

If you are interested, you may buy the issues from them

If you just want the articles, I am happy to scan them and email to you.

Hi Peter, is it okay for me to send them to ?

"Deadlegs"

Sorry, I mean if you can’t get a copy from them then I will send them to you
in pdf.

"Camera"

Robert,

I was "thrown" a bit by the image changing mode when I trashed the channels. This helps thanks.
