White Balance Eyedropper Develop AP iPad

[wgphoto]

Something to add to improve the develop module would be an eyedropper for white balance off of a gray card image. Since Photo doesn't have a way of opening multiple images at once, you'd have to record the white balance from the gray card image, then open the images you want to edit and input those values, but t's a start. Maybe the DAM will come at the same time and we'll be able to apply to multiple images, wouldn't that be something. Non-destructively? OK, enough.
