So what do people think of the new tools apparently available in iPhoto? Apparently there are shadow, highlight, and noise reduction sliders now, a selector for chosing a white spot on the picture to set white balance, and the histogram gives you the ability not only to set the end points but the mid-point as well. Seems great to me. Those are all features that made me want to upgrade to something other than iPhoto. I realize that more serious users probably only edit photos in a real photo editor, but to me, iPhoto has seemed acceptable. I would still like a better retouching tool and access to color channels, but this seems like it will satisfy me for a little longer.
