I know most Digital Cameras allow you to shoot in Color, BW, Sepia and possibly others...
Do any of you actually shoot in these alternate modes (anything other then color) or do you just convert and play with the images in PS to the color scheme you want?
I've taken some BW for work, knowing it'll be printed in BW only. I'm wondering (yes, I could go test it out...but I'll just ask) if there is a difference from shooting in BW mode or converting a Color image to BW in PS?

Color, break it into RGB channels and play with the desats of each channel with transparency to get the combination you like. Much better than the generic BW mode.

my canon I only shoot color because it does not have a b&w option.
my Kyocera I mainly shoot in b&w. its smaller, and i can sneak it to work as my 'spy cam'.

When I was using my Fuji FinePix S5100 I would sometimes shoot in B/W because it seemed that I was loosing details on dark pictures when I shot them in colors and then processed them through PhotoShop.
But since I have my D70s... All colors! The shots I want in B/W, I convert them in the raw file. |

I'm understanding, or misunderstanding, that alot more information is captured on your sensor in black and white than it is in RGB mode. Therefore if your intent is to output a black and white image, why not shoot that way as to increase resolution rather than converting from RGB?
Oh yeah....I got this little tidbit from the "Digital photgraphy for Dummies". I haven't tried it but it seems to make sense to me. Any thoughts?

Agreed. Even if my camera did take in straight B&W (it does sepia only) I'd still take in color and convert for the the reasons rblanton pointed out.

The exact same amount of info is cpatured, whether you shoot in B+W or color. Retaining the color information simply allows you the flexibility of:
1.) Deciding later whether to convert to B+W
2.) Deciding HOW to convert, that is, which color channels to combine, and in what amounts. You can even decide to use a "negative amount," essentially subtracting some of one channel.
The end result of shoooting in color and converting later is more time expended, but far greater flexibility and better conversion quality. |

I find using lab mode in PS keeps the tones a lot better

| i do both. sometimes it easier for me to see if i like the way the pic will come out if i shoot in B&W. i prefer most of my b&w shots to my color ones so i tend to use it a lot. im also not the best at PS so, maybe as i get better i will just convert...who knows |

The exact same amount of info is most definitely not captured when shooting in B&W compared to colour. Each pixel in B&W has 256 (8 bit) graduations of light it can record. Each pixel in colour has 256x256x256 (millions) graduations of light, as you're using three different colour channels for each pixel. For the camera to produce b&w photos in-camera, it has to throw away information by the millions to produce 256 levels per pixel. This is why it is WAY better to do this in Photoshop using channels. |

Shoot raw+sm jpeg in B/W mode when you know you want a b/w. This way you get to preview the b/w version but you still get raw and all the color.

| I try to shoot in the mode I am going for...if I do shoot in b&w, I can alter the curves in PS, if necessary, as well as the other ways that are mentioned before me on this thread. |

20D has b/w mode. He shoots in mode that captures a RAW file and a jpeg, so it's a rather large file. This gives a RAW file to play with later a jpeg image that you can send through email, view on a portable hardrive,etc.
