    Do you guy use a grey 18% card or a white one or both?

    Any links to how to use them with lightroom.

    the local store I was at only had 18% grey cards... does this works for exposure and/or white balance?

    Thanks!

    18% grey is really not needed. And neutral color that is not pure white or black with suffice. and then snap one image under the lighting conditions with it. And then in post in ACR open all pics shot under the same conditions and get your white ballance tool and click teh neutral cards and it will WB correct that picture and then shift click the rest of the images in ACR and hold the alt key and click synchronize adn now all pics will be corrected. Literally takes 20 seconds

    in lightroom you can hit the W key and then click on the neutral colour to set the WB. i'm not sure how to do it to all the pictures but it can't be too hard to find./

    I use a gray card when ever I'm shooting and want to worry about white balance when working in Aperture. Always carry it with me, though.

    do you use it for adjusting WB in camera or for use later? I use to use it for in camera WB but then I would also check the difference in post and adjust in post and like the result better

    I remember seeing a video here of a guy showing how to use a very small one and adjusting the images afterwards, he was taking a model with like a purple light and correcting to normal colors in the software afterwards

    Before starting the what ever project I'm working on, I'll hold out my gray card and take a picture of it then shoot like normal. Once I import all the photos from my camera, I'll do white balance on the gray card, then lift that adjustment and stamp it onto the rest of them in that set.
