Here's some good advice for anyone who uses a digital camera on how to balance colors by using a gray black and white card from the nice folks over at The Digipix. My photographer friends all use these and it makes a world of difference. The advice in this article might be a little techie for those new to digital photography, but you can follow it without using LightRoom. In Photoshop, create a new curves layer (always use an adjustment layer if you are in a newer version of Pshop so you can tweak it later). Then click the black eyedropper and click on the black card in teh image. Use the white and gray eyedroppers to click on the corrosponding cards — which you've placed just at the edge of your photo - where you can easily crop them out. Now watch how fast your colors will snap into true.
