Thanks for all the feedback guys. When I get an opportunity, I'll have a play with your suggestions (blown reds the common theme) and see how they come out. Just to answer a few questions:
Increase the exposure overall, just a little - You don't want to lose that early evening feel - but reduce the exposure in the red channel. Perhaps just back off the saturation will do it. Otherwise you would need a PP program that will allow you to adjust each of the channels independently
I'll give it a go when I get a chance. I'm using CS3 and I understand what you're talking about. oh, and it was morning, not evening
If you're using some form of average metering - matrix in Nikon terms, or evaluative in Canon terms - then this becomes more problematic, as the metering system tries to bring everything back to what it thinks should be a normal type of image ... which is not what you're shooting.
I generally use spot metering most of the time, and because of the tendency to blow reds, I will meter of the red, but dial down about 2/3 of stop to counter this
Depending on the situation, I vary the metering
mode. For this one I was in spot with -1 EV, however this was metered on the water, not the flower.
As I mentioned, when I get a chance to have a play I will, but unfortunately for all of you, I'm off to Kakadu, Litchfield, and Katherine Gorge for the next week. I will no doubt have something to show when I get back.
Thanks again.
