When you half-press the shutter, you're actually locking *both* focus and exposure ... so, if you meter off the sky and then want to recompose on something near-by you can end up with a very out-of-focus pic.
Pressing the ISO button allows you to completely release the shutter button, recompose on anything you want, and then take the picture (re-focusing as necessary) with the same exposure settings. You can even change the settings (shutter speed or aperture; it's called Program Shift) with the omni-button, without changing the overall exposure.
Here's a link to the on-line manual for it.
Thanks, Stitch! I don't recall seeing that tidbit of info in the S3 manual that came with the camera or the Short Courses book, but it's been a while since I read thru them. Now that I know the camera better, I guess I'd better re-read the Short Courses book and see what else I missed!
It's funny, but I can look at other people's photos and see what they did wrong, but when I'm taking a picture, I tend to forget all the little details. I was taking pics of my DS and his homecoming date this weekend, totally forgetting about focus - the square in the center of the viewfinder was focusing on the bushes they were standing in front of rather than their faces. DUH!
As soon as I looked at the photo on the computer, I wanted to scream! Of course, it didn't help that they were getting impatient at me for taking so many shots, so I was trying to rush and just not thinking....
Ah well, one of these days all this will be second nature to me and I won't HAVE to think about it!
Was the last one taken from the Dolphin? (I have almost the same shot.)
