B&W Shoot in Cam or in Post?

Sorry if this has been covered, but coudn't find it. IF I want a B&W look is it better to shoot in camera in the mono mode or convert after the fact and bleach the color out in PS?

I usually do it in Lightroom instead of in cam because, IMO, it looks better than the in-camera processing, and I can have both the B&W and color version.

I think my 40D produces acceptable BWs sometimes. Of course not as good as Silver Efex can do, but I shoot with Raw+Jpeg on the monochrome setting, contrast all the way up or close to it. It gives you a good idea of how the subject looks in BW, if nothing else. I feel comfortable with rules and consistency, so it's almost a relief to shoot them in camera and know that it will process them pretty much the same, rather than shoot in color and convert later and get varying results. I'm weird.

I shoot full color 99% of the time and then just change it after if the image doesn't seem to work in B&W. If you shoot it in B&W... you can't change it to color (not that I am aware of ) if you shoot color you can always change to B&W.

CW..I realize that...but is there ANY difference...better or worse or same shooting in BW or Proscessing after the fact in BW?

Not that I have honestly noticed. When I shoot film I only shoot black and white because I like to B&W and some grain/noise (hence then 400iso or 800iso film). I know with my 30D they pretty much look the same. IF you really want me to I could do some testing of it and shoot a couple images and full color and then convert to gray scale, and then a few shot in gray scale. I should have some time today.

thanks

Generally when I want B&W photo, I'll make it B&W in Lightroom or Photoshop.When one shoots B&W from the camera, there is less versatility as to how one wants the monochrome to look. However for B&W projects, I usually use the feature within the camera, and throw on a yellow or red filter (contrast). I do this because I wish to keep as true to my vow of B&W as possible.

In general, if you're shooting with a DSLR, the best thing to do is, when you've loaded your photos into the computer, make them B&W there.
