VV, Ken

perhaps a couple of pictures will help. These are screenshots from Adobe Camera Raw, a program that allows camera-type adjustments to an image in the computer after taking the shot and seated comfortably in one's chair. If you goof up when taking the shot, the RAW image is much more flexible than a jpeg. One thing about it is that it doesn't give you the heavily saturated and contrasty images that come in JPEG straight from the camera. The photographer gets to choose how contrasty and saturated the image is. Anyway, the picture that I chose was 'Blushing Knockout' Rose, with a similar color to 'Perkins Pink.' It was taken on a calm, misty/rainy, evenly lit day in Mansfield, OH without flash; perfect conditions for photography. In ACR, I have adjusted the exposure in this image by -.50 stops until the red channel quit clipping the right edge of the histogram. See the cerise-colored circles. The whole red channel being in the histogram means that all of the red color that is possible is now availble to see. The foliage in the background seems a little dark. Note: once a person "learns" what their camera can handle without blowing things, you can over-expose a RAW somewhat and then pull it back in ACR and still recover all of the information. Techno-freaks like me do this to maximize the signal to noise ratio and hence, overall image quality. It's pretty complex and I don't have time to a good job explaining it. If anyone is interested, here's a link to a lot of links: http://www.google.com/search?hl=en&q=expose right Raw
