I've recently bought a Canon 700D and am still very new to it, although I have a good reasonably good understanding of photography basics (aperture, shutter speed, ISO, DOF, focal length etc.)
I mostly shoot in Av mode.
I've noticed on a few photos that the colours are getting blown out - not as a general exposure thing, but on one channel, e.g. red. This is losing all the detail in, say, Autumn leaves. My last camera suffered with this and I would overcome it by under exposing, shooting raw and post-processing myself, but I'd sort of hoped that this one would be a bit better.
Here's an example (the black bits are clipped highlights - clipped on red channel):
Is there anything I can do about this? Should I always look out for strong colours and dial down the automatic exposure?
