Is there any benefit in shooting on the B&W setting rather than just desaturating colour images on the computer? I know B&W film has much better exposure tolerance than colour film but doubt if the same applies to digital capture.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

No, the B&W mode just saves time if you know you want it and is a "feature". You'll have far more control by taking in color (especially if using RAW) and then desaturating. With digital cameras the sensor is the same whether shooting color or using B&W mode...but the B&W mode is just discarding much of the information.
This was posted in the Nikon area but it's the same for Canon cameras, you have to select the lighting type you are shooting under, be it fluorescent, incandescent , tungsten, sunlight or flash (menu item). If your camera has a White Balance check or setting try to go through that setup, there may be an auto white balance where you point at something white take a picture while setting it and you are set. If you go to another area with different lighting you'll have to redo it, also with Nikon if you turn off the camera you will have to reset it. I know this is after the fact (12-30-08) but if you have the shots and have Photoshop or even Adobe Lightroom you can adjust the warmth out of the images so they are more natural prior to having the photos processed.
The Nikon D70 does not have a black-and-white mode setting.
However, you can take your photo in color and then use software to convert it to a grayscale photo. (Black and white implies an image with only those two values per pixel; grayscale can have 8 to 16 bits per pixel.) Most photo editing packages have a "desaturate" feature that does an automated conversion to grayscale.
The open source image editor Gimp has a "channel mixer" dialog that would allow you to approximate the effect of various filters before performing the desaturate function. This would allow you to experiment with the procedures if you do not have a commercial photo editor like Adobe PhotoShop. There is a special wrapper of Gimp that puts its interface into a configuration like that of PhotoShop; look for "GimpShop". The open source image manipulation package ImageMagick may also be used if you prefer working with command line utilities.
264 is the minimum number of shots you can fit onto the memory card. A shot with large areas of black or white uses less memory than a more complex image and so the camera recalculates the number of shots remaining and so the number appears to go back up to it's original value.
During shooting, or when the shutter-release button is pressed halfway, the number of images that can be stored in the memory buffer at current settings is shown on the exposure-count displays in the control panel and viewfinder. "r06" indicates that six images can fit in the camera's buffer, "r08" would indicate eight frames. Any other number could be displayed as well. Burst mode is used when you want to hold down the shutter button and continuously shoot. You are probably shooting in burst mode and your buffer is full, set the camera to single shot and see if that helps.
Hey mcgeedds, What you’re seeing is probably what is called digital noise. At low levels of light the sensor in the camera that records the image shares data from one pixel to the ones adjacent to it which causes digital noise. The way to fix this is either make sure your noise reduction setting is turned on, or get a powerful off camera flash that has the power and coverage capabilities to light the subject at the distance you are from your subject. Noise reduction on average should double your exposure time requiring you to use a tripod in most cases. Also pay attention to your iso setting if it is too high this can also cause digital noise in your images. I almost never shoot with a higher iso that 400. I hope this helps.

That's just the quirky autofocus of the d80. Try tilting the camera diagonally to focus and tilting back up to shoot.
Unfortunately, autofocus issues like those are the difference between a d80 and a d200/d300 :/
Have you had the picture printed at a local photo lab. Try that and see if it's your computer/printer matching.
You may have to see if the Camera is set for Adobe RGB (or RGB) and your computer/printer is set for Adobe RGB or sRGB. These need to match. There's a new world with color matching that the point and shoot don't do.
Hope this helps. I could regurgitate all about Color Matching, but why when someone else has it all written out.
