The Beauty Passes provide a rendered view of the different aspects lighting the scene, such as shadows, highlights, reflections, illumination and color. Beauty passes are rendered together with the main beauty pass (the normal rendering). I.e. each one of these requires its own film buffer that needs to be stored additionally to the main film buffer on the device.
Beauty Passes include the following shown in figure 1.

Activating the Raw option allows more control over the final look in post-production. If you check the Raw button, you will get the image similar to beauty render. Since you specify the render output format from the file and format field most of the time, you can turn this option off.
