Adobe Photoshop Levels Command

LEVELS COMMAND

Go to the LEVELS adjustment either by IMAGE > ADJUSTMENTS > LEVELS or simply command + L.

You'll see a histogram; which is a graph charting the relative amounts of light and dark in your image. You'll see that it doesn't make it all the way to the right of the space in which it sits. Click and drag the little white slider on the far right of the histogram to the left, just enough to meet the rightmost edge of the histogram. As you drag it make sure PREVIEW is checked and you can see what you're doing. Hit OK and you're DONE!

Hold the OPTION key on Mac while doing this and the image will go to super-high contrast. Drag the white slider left until some points just start to sparkle out of the black background. Take your finger off the Option key to see how the image really looks.
