Before I started this trip back into photography, I always wondered why some of my indoor shots would have a strange orange-red cast across the picture. Not knowing any better, I just lived with it.
However, after discovering artificial light the reasons for strange colour shifts is a little easier to digest. Previously, I had just thought that all light was just the same - whether it came from the sun, the lights indoors or the lights in an office building etc.
But this is not the case. All digital cameras tend to have a 'white balance' which tends to be left in auto mode. What this means is, the camera will assess the scene and then decide what type of light it sees and then adjust accordingly... ok, but adjusting to what?
