Chapter 8. Understanding Colors and Channels > Using the Exposure Adjustment

Using the Exposure Adjustment

Photoshop's Exposure adjustment () is primarily designed for performing tonal adjustments to 32-bit High Dynamic Range (HDR) images, but it works with 8-bit and 16-bit images as well. Exposure works by changing an image using a linear color space (gamma 1.0) not the image's current color space. When used with HDR images, it gives you the ability to draw out details of the image that otherwise might be completely lost within the shadows and highlights.
