Assess the image
Zoom to 100% and scan the whole image, making note of the adjustments that will be needed.
I'll do a post on non-destructive retouching layers, suffice to say, now is when you would be doing that.
Starting with luminosity & contrast then color & saturation
Contrast will effect how you see your color and saturation
Layer adjustments that are masked off, again, luminosity first then color.
So there you have it. If you stick to this guideline, as you build bigger and more complex image files, you won't be creating adjustment layers that counteract each other. That would be extra work and can cause noise and banding.
Good luck and happy pixel pushing
