With this last photo, I decided to do some very quick tweaking. I've upped the contrast and saturation quite a bit, and also the brightness and colour temprature ever so slightly. I would have liked to have done it in something that gives me control over saturation for each of the R/G/B colour chanels, but I was just doing it quickly and didn't have that option, so the reds are a little strong. What do you think? I think it looks good for a first attempt.
