Photo Editing
In Adobe Camera Raw
The way to edit raw images from digital cameras. Best explained by demonstration in class, this link has an excellent explanation to refer to later: http://www.photoshopessentials.com/photo-editing/camera-raw-vs-photoshop/
In PS with destructive adjustments
The Image Menu > Adjustments choice has all the adjustments you need but...the problem is that the changes are all "baked into" the file. You can undo but you can't tweak them later. Only use for quick and dirty, simple edits.
In PS with non-destructive Adjustment Layers
All the adjustments you need plus they are all applied via an "Adjustment layer" which allows you to go back and tweak them to your heart's content. And you can use Layer Masks to apply the effects to specific regions of the image.
