As discussed in the prior post Show Me Your Histograms the tonal range of an image represents the amount of contrast in the image and is determined by the image’s distribution of pixels, ranging from darkest pixels on the far left (blacks) to the lightest pixels on the far right (whites). One of the ways to adjust the contrast and make color corrections in your photo is the Photoshop Adjustment Tool Levels.
Disclaimer: I am by no means a Photoshop guru, expert, teacher or anything of the sort. I’m a lifelong student studying to understand the concepts that will make me a better photographer. When in doubt Photoshop Help is the place to go.
