The order you choose to layer the exposures in Photoshop is dependent on your personal preference and the exposures you’re working with. Sometimes, in scenes of extremely high contrast, you may need to use as many as five to ensure a smooth transition between exposures and to cover the full range of light in the scene. You are not limited to the number of exposures you can blend. Your brightest exposure should contain information in the darker areas, while your darkest exposure should contain information in the brightest areas. Ideally, the exposures you choose to blend should cover the full range of light in a given scene.

While some HDR programs nowadays produce very natural, clean HDR images, luminosity masks do not affect the original files at all, so there is literally zero image degradation during the blending process. They give you incredibly fine control over your imagery in almost every area. Through the use of luminosity masks you can create stunning, balanced images that encapsulate a vast dynamic range of light. While you, and many photographers, may have relied heavily on HDR programs in your exposure blending quest, many more are now beginning to turn to luminosity masks as a cleaner alternative. ![]() Image created by blending two exposure with luminosity masks, one for the sky and one for the foreground. ![]()
