Here is another example of Foveon and red. I'm not sure why I'm posting yet another example, perhaps because it's so easy to deal with and there seems to be a never ending discussion about this.
I made 2 quick adjustments to this image, one of them Vignetting. I would have made this adjustment to the image regardless of sensor; darkening the edges a bit keeps the image together somehow and focuses the attention on the roses. I have darkened the edges of my (B&W) prints long before I ever knew there was an actual term for this action. First time I heard vignetting I was thinking about a vinegar salad dressing.
The other adjustment was to "Fix" the red as pink phenomenon I notice with the DP1. The steps for this in Aperture (and probably in other programs) are just about as easy as it gets.
Aperture has a Color Correction Tool. When selected it opens a loupe and turns the cursor to an eyedropper. Clicking on the offending color selects it. The adjustment sliders are Hue, Saturation, Luminance and Range. Hue is the fixer. I select the red and simply click the slider to the right (towards yellow). I have found that 10 or 11 clicks usually do it. Saturation and Luminance are self descriptive and Range allows me to adjust the sensitivity of the color selection from "Razor sharp" to "Broad brush."
I used the AML-1 close up attachment and grabbed a couple of quick shots. I had no time to properly work this scene but the colors are what I was looking for.
