The central object of a good picture should normally be that part of the image in focus and correctly exposed, except if a silhouette is intended.
Yeah, I tried to use a couple of the PSE tools (Quick Selection, followed up with New Adjustment Layer, Brightness/Contrast) to cure that area, but not much luck. The original is even a tad worse, actualy. What with the bird being the main subject and all, I tried everything I could. There was no time to make any setting adjustments at the moment of the shot. These Korean birds are quite skittish. I scare off a dozen for every one I get a decent shot of. If I recall, I scared this fella off the paddy once, drove away and shot some other farms and such for at least an hour, came back and managed to get this and one other before he flew off again. And this was full-zoom on the Sigma! Sheesh! I'm thinking maybe a few of these wind up in the stewpot often enough to make them wary of anyone who pays attention to them.

<CJ>Very nice, but the blue stool should be a few shades lighter, and the petunias on the left should be a blush pinker. </CJ>

Hence the need to find the exposure override on the camera, it's often one of the most common controls. Once you have lost detail in the camera you are buggered. If you have a tendency to over expose in your shots then set you camera to under expose a little and leave it there for a while and see what happens.

You're right, of course. I read in the manual about how to do that, but I haven't actually done it enough to be able to do it on the fly like I need. Practice, practice, practice...
Edit: Ah! Now I remember. It was an overcast, gloomy day to start with, so I just assumed that it wouldn't burn out. Now I know better than that. Will become adept with exposure override
post haste.

As you have now guessed the camera doesn't know it's overcast, just what light coming through the lens. If there is a wide range of contrast in the scene and a small area of very light colours there is always the risk of a highlight burn out.

Ah. Right. Not just absolute but
relative magnitude/intensity. Range of contrast. I have to break the habit of thinking about it the other way. It's not really so different from setting an old x-ray machine in that respect.

Thanks! I've been meaning to shoot that couple for months now. So to speak.
mostly it's the exotic material, though. nudge nudge wink wink
