Normalize colour with Grey Card

[andres91]

Hello everyone. I'm taking several photos with a neutral gray card and the gray card is seen in the image. In Photoshop there is the option of using an eyedropper in the gray of the card to normalize the color. (in Levels menu) The option is "Gray Point eyedropper in the Levels menu". Is there such an option in ImageJ? Any plugins? I searched but did not find anything.

Thank you very much!!
