Let’s break these down: Range, masks, Lightroom.
1) Lightroom, of course, is the best workflow software for the photographer. If you shoot a lot of photos, even smartphone photos, Lightroom can be useful. (But why use only a smartphone if you love taking photos? Use a DSLR camera, or one of those mirrorless wonders! But I digress.) The point is: Lightroom is the best workflow app if you shoot photos.
2) Masks. This is how you select areas in your photos, much like selections in Photoshop. You mask an area – use any of the local adjustment tools in Lightroom (Graduated Filter, Radial Filter, or the Adjustment Brush) – and apply your edits to that area (exposure, texture, saturation, etc.).
