I mentioned in another thread that I like to use a target in my pictures and then crop them out. What I meant was, I like to use a gray card for color correction.

[All photos had to be resized and jpg quality reduced in order to meet the requirements of the forum, but I hope you get the idea.]

The original picture from the camera:

Loaded into Photoshop, note the gray card along the bottom:

Here, I've selected the area of the photo I want to keep and then used the Level control (CTRL+L) with the eye dropper to set the black, white, and midtone levels from the respective areas of the gray card:

Next, it is copied into a new window. I noticed that my little stand was visible so I would use the healing tool to erase it, but I'm lazy and didn't do it for this example:

The final result of using the gray card:
200711362236_example_5.jpg

I hope you enjoyed my little photo essay. I am by no means an expert on the subject, I just wanted to share my method. Enjoy! [8D]
