Optimize with Adobe Photoshop

 

After youÕve selected your final images (which I call ÒheroesÓ), you may need to fine-tune, or ÒoptimizeÓ these images. These heroes are the ones that will be printed, critiqued, and turned in to me.

 

If youÕre looking at one of your heroes in Bridge, simply double-click on it and it will open in Photoshop. If youÕre looking at your files in a folder, drag the desired file icon over the ÒPsÓ icon in the launcher.
