I'm looking for a way to set a custom white balance on the D70. Reading many of the posts, there seems to be a concensus that using the auto white balance setting is not going to achieve the best results.

I found a "Lastolite EZ Balance Collapsible Light Balancing Reflector Grey, White - 12" that looks interesting. Has anyone used it or have a better option/suggestion?

Thanks,
Jean-Maurice

You can use any gray card or white card to do a custom white balance. Each camera does it in a different way. For example on my Canon 20D, I shoot the white card full frame in the lighting I'm adjusting for. Then from the 20D menu, I pick the shot I just took of the card. I then set the camera to Custom White balance and get perfect balance for that light setup. By the way it seems to make no difference whether you use white or gray for this purpose. See my post about White or Grey? for more info on this subject.
The card is also great for zeroing in your exposures or calibrating your digital camera using the card and the built in histogram.
Cheers,

I use the Westscott Digital Calibration Target. It is similar to the lastolite but bigger 24". It's black gray and white on one side and white on the other. It's kind of expensive (90 USD) but it absolutely nails the color. It paid for itself after the first few uses just in time savings during post production. Also, having the black, gray and white on the same side makes exposure a snap.

I have the original version of this target which was 32". I use it both form white balance, exposure calibration and a white reflector. You can still get the original at http://www.photovisionvideo.com/target.html.
The original was targeted more for calibrating exposure than white balance. Using the cameras built in histogram and the card allows one to zero in exact exposures. It also comes with a one hour video by the inventor.

I use a grey card, or if I'm traveling light, a pringles lid.

Go to the largest paint store and pick up some of the free paint sample cards. Pick up some of the cooler (ie cyan tint) whites and even some of warmer (ie yellow) types.

The cool ones will give you a warmer tone in your images and the warmer ones will cool down your images. Play around and note the ones you like the best.

Do a search for Warm Cards on the net. I use them when shooting video and I love them. They have a set for Digital cameras.

No need to search the net for info on "warm cards" as the link is on the home page of Garage Glamour under the "Photo Resources" section.

I played with one, but they are too expensive and you either have to buy one for each lens that has a different filter size, or you have to just hold it in front of the lens. I found that the coffee filter method worked just as well and coffee filters are very cheap.
