Image created by blending two exposure with luminosity masks, one for the sky and one for the foreground. 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. Through the use of luminosity masks you can create stunning, balanced images that encapsulate a vast dynamic range of light.
They give you incredibly fine control over your imagery in almost every area. 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. That is why so many digital photographers are beginning to make luminosity masks a staple in their workflow. What are Luminosity Masks? Luminosity masks break an image down into various channels of luminosity. In other words, they allow you to make very specific selections in Photoshop based on how bright or dark an area is.
Let’s say you were looking at a beautiful nighttime cityscape shot. Everything is exposed correctly apart from the street lights, which are completely blown out.

Secondly, it is imperative that you have a good understanding of Masking in Photoshop. If you’re a little bit unsure of the process, you can visit Adobe’s site which has a useful video tutorial for you to follow:. Which exposures to blend? Ideally, the exposures you choose to blend should cover the full range of light in a given scene.
Your brightest exposure should contain information in the darker areas, while your darkest exposure should contain information in the brightest areas. You are not limited to the number of exposures you can blend. 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. The order you choose to layer the exposures in Photoshop is dependent on your personal preference and the exposures you’re working with. Usually working with your normally exposed image as the base layer will derive the best results, but sometimes you may need to work with a darker or brighter exposure as your base layer. Once you’ve decided on your exposures and have layered them in Photoshop, you now must decide which exposure you will run the actions on.
