I was reading about setting the white balance by shooting on an 18% grey card or something called a "warming card set."

I'm wondering if the grey card method is the best bet. I tried shooting at a local middle school b-ball game last night and got bluish w/ incandescant setting and yellow w/ fluorescent senting. I tried direct sunlight, just for kicks, and got yellowish also.

Would using the grey card get a better result?

I've used a white card to set the white balance and the results are very impressive.

This is an example taken under street lighting with auto white balance.

And this is the same subject same conditions with the white balance set.

There is no flash used for either shot.

Nagasaki, I'm confused you say you used a 'white' card. Do you mean an 18% grey card for white balance? I use a plain sheet of white paper but depending on the brightness of the paper your setting will vary.

Brandofamily, I've heard of the warming card set and saw a reference once but can't find it do you have it? If memory serves it was about $45.00.

Remember that you can fine-tune the canned WB settings with the Sub-Command Dial.

Suzan, I used a plain white envelope to set the white balance for the shot above. I guess agrey card would be better but the manual says grey or white. I've used the same technique underwater where a white plastic slate was easy to get hold of but a grey card would have been very difficult. I may not be getting a perfect white balance but it's doing far better than any of the standard settings. I have found on some of the shots I've taken underwater I've had to drop the exposure by 1/3 stop when processing the raw file so that may well be the result of using a white card instead of grey.

With the cost of flash memory dropping, i just bougth a 2Gb Sandisk ultra 2 for $172 usd, shoot in RAW format then you can adjust white balance and other settings on the computer after the fact if needed. I found thatmy D70 is really superior in RAW mode so that's why, i went for the big memory.

If it were, wouldn't the image be UNDERexposed?

You're right it should be underexposed.
