White balance

auto white balance is good – particularly in mixed lighting – but it can suck some of the life out of strong colours that it sees as a colour cast: the cool blue of dusk and dawn, for instance, or the orange glow of a sunset. Choosing a preset, setting, a Custom White Balance or dialling in a colour temperature using the K (Kelvin) option that’s available on some cameras, will avoid this. And on top of that you can preview the effect in real time on the Live View display.
