Photoshop has a variety of adjustments that can be made to an image. These adjustments include brightness, contrast, levels, curves, hue/saturation, and color balance. Each adjustment can be used to improve the appearance of an image or to correct problems with the image.

Image adjustments are changes you can make to an image to improve its appearance. There are a number of different adjustments you can make, including brightness, contrast, saturation, and hue. You can also adjust the levels of black and white in an image, or add special effects like sepia tones or vignettes.

The three basic adjustments in Photoshop are brightness, contrast, and saturation. These can be adjusted by clicking on the icons at the top of the screen or by using keyboard shortcuts.

Levels adjustment is one of the most powerful and versatile adjustments that you can make in Photoshop. It allows you to control the tonal range of an image, making it brighter or darker, and adjust the color balance.

There are 16 adjustment layers in Photoshop: Levels, Curves, Exposure, Shadows/Highlights, Contrast, Brightness/Contrast, Hue/Saturation, Color Balance, Vibrance, Black & White, Channel Mixer, Gradient Map, Photo Filter, Selective Color, and Invert.

An adjustment layer is a layer in Photoshop that allows you to make global changes to an image. This means that the changes you make will affect the entire image, not just a specific area.

To copy adjustments in Photoshop, you can use the Copy Adjustments command. This command will copy all of the adjustments that have been made to a layer or selection and paste them into a new layer or selection.

The threshold adjustment layer is a Photoshop layer that adjusts the brightness values of an image. This layer can be used to lighten or darken an image, or to create a black and white image from a color image.

Tonal adjustment is the process of adjusting the tonal values of an image. This can be done by adjusting the brightness, contrast, and saturation of the image.

There is a big difference between levels and curves in Photoshop! Levels are used to adjust the brightness and contrast of an image, while curves are used to adjust the color and tone. Curves are also more precise than levels, so they can be used to make more subtle adjustments to your image.

Shadows can be adjusted with the Levels adjustment.
