Levels adjustment tips
Here are a few tips for getting the best results with levels:
- If you're using multiple adjustment layers, you may need to readjust the levels after making changes to other adjustment layers.
- If you want to compare the levels adjustment with the original image, you can turn the adjustment layer off and on.
- Generally, you'll want to adjust the black and white sliders so they fit the data in the histogram. For example, in the image below, we adjusted the white slider so it aligns with the right edge of the data:
Note that the histogram will be unique for every image. If an image has the proper exposure, the histogram will be complete, with no data missing—moving the black and white sliders in this situation would cause clipping. Instead, you can use the middle (gray) slider to increase or decrease the overall brightness.
