The "Enhance" feature of iPhoto does a good job making color adjustments to most photographs. I find I can use it most of the time for home snapshots, although I often followup with minor tweaks. I'm puzzled why Photoshop's Auto Levels and Auto Color features don't seem to do as good a job as iPhoto's Enhance button. Is there a writeup explaining how the Enhance button does its magic? The articles in the Apple Knowledge Base only give vague descriptions like "instantly brightens the photo or adjusts its contrast levels based on preset criteria." I'm a perpetual "advanced beginner" in Photoshop and I'm starting to use Photoshop as my editor application from within iPhoto. I'd like to know the steps to use in Photoshop to accomplish something similar, i.e., to make the initial adjustments to a newly imported photo without much thinking or experimentation. (I'll save those for the more important photos.) My goal is to be able to do this at least as well as iPhoto does.
