Why Can’t I Adjust Levels in Photoshop?

Last updated on September 23, 2022 @ 10:06 pm

If you’re new to Photoshop, you may be wondering why you can’t adjust the levels of your image. The truth is, you can, but it’s not as simple as just clicking a button.

You need to use the Levels tool, which is found under the Image menu. Here’s how to use it:

First, make sure that your image is in RGB mode. If it’s not, go to Image > Mode and change it.

Next, go to Image > Adjustments > Levels. A dialog box will appear with a graph that represents the levels of your image. The left side of the graph represents the shadows, the middle represents the midtones, and the right side represents the highlights.

PRO TIP: If you are trying to adjust levels in Photoshop and nothing is happening, it is likely that you have an 8-bit image. 8-bit images can only hold 256 levels of information, so there are no more levels that can be adjusted. You will need to convert your image to a 16-bit image in order to make further adjustments.

To adjust the shadows, move the left slider to the right until you’re happy with the result. To adjust the highlights, move the right slider to the left. And to adjust the midtones, move the middle slider up or down.


So there you have it – that’s how you adjust levels in Photoshop. By using the Levels tool, you can get your image looking just how you want it.
