Red flowers are difficult to photograph; mine usually turn out washed out in color and more pink than red, as you say. I'm sure more knowledgeable people can give you better advice on camera settings, but what I have found helps is to take the photo on a cloudy day or at dusk when the light is low, to cut contrast, and then I use my editing program not to increase saturation but to darken the picture. That generally gives me my best results. The photo of the glad I took yesterday is an example; it IS rather pinkish but this treatment made it look redder than it did to the naked eye.

You can also try working with your white balance. Even something as simple as setting the camera to 'cloudy' will take out the blue cast, and add more warm tones.

:) sure makes me miss my beautiful Azaleas from S. California days.
