Two common processes for astro images is adding hydrogen alpha details to an RGB image and dealing with the wide range of brightness (high dynamic range). This image has a wide range of detail in both the bright cores of the galaxies M81 and M82 as well as the much more faint Integrated Flux Nebula (IFN) that is also captured in this view. This video shows how to deal with both using Photoshop.
