If Shooting JPEGs, Use a Preset White Balance
If you're shooting with your digital camera set to RAW format, you don't need to worry about the white balance (leave it set at Auto White Balance, you can always change it later, in Photoshop), but if you're like many pro wedding photographers, you're shooting in JPEG Fine format (so you can take more shots and write to the memory card faster). If that's the case, then you're better off choosing a preset white balance in the camera that matches the lighting situation you're shooting in (that way, the overall color of your photo looks balanced for the light). If you don't set the right white balance, your photos can look too yellow or too blue. Luckily, choosing a white balance is easier than you'd think, and it will save you loads of time later when you're processing your photos in Photoshop. Just go to the menu on your digital camera, scroll to the white balance control and choose Incandescent if you're shooting in a standard reception hall, or Daylight if you're shooting an outdoor wedding. If you're using a flash, set your white balance to Flash. It's that easy to get your color in line.
