Foundations™ is a pack of powerful base adjustments that I use to set my base tones. It is designed to create a base look/mood to your an image. From there, tweaking to set your own style is as easy as adjusting a few sliders.
Why powerful? No matter how much you adjust the colors, if the tones don't adjust along with them, then the results may not be as pleasing. Try these tones adjustments that I've been using for all my edits.
