Color Correction

The photo on the left was taken with the camera on auto white balance, while the one of the right was taken with a preset white balance. The photo taken on auto white balance is colder. As added insurance a gray card is visible in the upper right corner of each photo, which can be used in Photoshop to easily correct the color cast. In practice I actually have even less of the gray card showing, which can then be cropped out. Some work was also done on the right hand photo in Photoshop with the "levels" to improve the contrast,brightness and tonal range.
