Kind of a stupid question, but I will go ahead and ask anyways. I have a Canon 20D and I wondered if there is any difference in taking a picture with the camera in B&W or turning it into B&W later in a program like Photoshop. I would assume there is not, but I figured I would ask anyways. Thanks.

I can be wrong... but is it true that a camera sensor only captures the color info from each RGB pixel?

-> process B&W in camera vs external (more flexible)

holy cow yes...

lol, there most definetely is!

i would strongly suggest you convert in photoshop (using channel mixer, or calculations)

the camera just tosses the color information, so you have no control over the tonal values

photoshop will allow you to get it to where you want it

Folks are giving you some incorrect info on this thread.

They're well-intentioned. Their just assuming that the 20D offers a single B&W conversion, when it offers a choice of tones.

If you have experience with B&W photography and how filters affect B&W images, you might experiment with the B&W feature of the 20D.

My preference is to follow the advice others have given you on this thread. Shoot yourt image in color and use Photoshop to make the conversion to B&W.

I have a bunch of learning galleries, tutorials, and Photoshop action sets for converting images from color to B&W on my site:

http://www.thelightsrightstudio.com

Just go to the Digital Darkroom. From there, you can explore Learning Galleries, Photoshop Tools, Tip of the Week (a previous "tiup of the Week" also covered B&W conversion), and Tutorials. There are lots of B&W resources free for the download.

Cheers,

Mitch
