Scott Kelby Quotes
As far as digital technology has come, there's still one thing that digital cameras won't do: give you perfect color every time. In fact, if they gave us perfect color 50% of the time, that would be incredible, but unfortunately every digital camera (and every scanner that captures traditional photos) sneaks in some kind of color cast in your image. Generally, it's a red cast, but depending on the camera, it could be blue. Either way, you can be pretty sure-there's a cast.
