It’s all about what happens when you give the digital mule its head. The light meter on your digital camera ( the mule ) is a very smart part of the mechanism. It’ll look at each scene you set before it and try to make it look good – decent exposure, no lost highlights or shadows, no noise. Frequently it will fail because you have overtaxed its capabilities…and even more frequently it will give back different results with each successive frame. That’s why wise shooters determine what they want first and tell the camera what to do instead of just accepting what comes out the chute. But so many of us use the AWB setting… It’s hard to get a good result when the people who have made the scene have set up a dominant colour or an overwhelming light pattern. The meter sees and judges and the only recovery from it is a RAW file and some slider work later. Too many disparate scenes...
