Usually I set up the white balance focusing on A4 white paper. Yesterday my photographer suggested to try and do it with Kodak Grey Scale card. Its wasnt big enough to focus on it, but I did the maximum and pressed AWB button.The result looked somehow even better that my usual WB. Can grey card can be used instead of white? I mean do they neutral same?

ABSOLUTELY!!!
The only difference between 18% gray and white is the luma signal. IN fact, in many ways an 18% gray card is better suitted. In fact, the camera's exposure meter is probably calibrated against a gray card.

I have one also and I use it to WB with. I agree with Bill, many camera metering systems are calibrated to an 18% gray scene.

Thanks guys, so my "subjective" preference for that kind of WB is approved..:-)
Need to buy big grey card, its difficult to focus on the photo small card.

Let us know where you get one in the size you need. I'd like to try it, too.

You can use a white card and set the camera's exposure to a point where it's about the same brightness as a grey card. Use your camera's "marker" feature to confirm the exposure level if necessary. The results will be identical.

I use grey all the time, it gives a nice warm glow to the image :O)

A grey card should add NO coloration to the white balance. If, in fact, you're getting a warming effect, either your process is flawed or your grey card ain't gray.

I'd like to get my hand on a grey card. What's the exact term for the card? Grey card?

Here you go.

Thank you. Grey/gray. That's why I couldn't find it on B&H ;)

You know it all now, but of course you can white balance on anything from pure white through to jet black.

And if you haven't a clue what setting to use (sodium lighting in a street scene at night, say) then go to wide angle and push the manual white balance button - like me you could well be surprised art what a huge range of colour balance options are built into your camera, and how well it copes. It could well make post CC unnecessary.
