Why Curves and Levels Are Important
Curves and Levels are the bread and butter of photo editing, but it can be difficult to know which one to use. Today we analyze both, and give the strengths and weakness of each. I also cover when I use levels and when I use curves, and how to make the process more simple.

What to use if you don’t like graphs
There is a hand tool in the curves adjustment layer that will allow you to click directly in your image and change your values and colors based on where you click. It takes all the technical stuff out of editing, and just leaves the fun. Highly suggested.
Curves
In general, curves are a bit more user friendly, and will allow you to make more dramatic changes than levels. With the ability to change things drastically comes the ability to either really mess an image up, or make it great.
Here is when I will use Curves
Adjusting the colors of highlights, mid-tones and shadows
Adjusting very specific values (Using the Hand)
Creating Vignettes (Pull RGB up in center slightly)
In compositing, often you will need to change colors, lights and darks to make an image fit. Curves handle this very well
Making drastic changes
Levels
Levels are perfect for large global adjustments such as making the lights of an entire image a little less bright. They are a bit more subtle than curves.
Here is when I use Levels
Making subtle changes
Adding slight color to highlights and shadows (as depicted in the image be Annie Leibovitz below)
Making white leves slightly darker so things don’t look blown out
In this amazing image of the White Stripes, Annie’s retoucher Pascal Dangin uses levels to add the perfect amount of cyan into the shadows. This is a perfect application for Levels. .
