Pros: Advanced color editing; advanced RAW editing; industry standard; built in file and organization system; wealth of resources, tutorials, and books, so it will be much easier to find wholesome, “Lenspiration approved” content; non-destructive layer based editing; works with Adobe Photoshop well.
Just a quick clarification… Adobe Lightroom does not support “layer-based editing” in the same sense that Affinity or GIMP or Photoshop does. LR does have non-destructive editing, but it does not have a “layers” panel that lets you edit individual layers. Most of Lightroom’s controls are global, (meaning that they affect the whole photo) but it also has some local editing tools, (like spot removal and adjustment brushes.) If you are looking for “layer-based” editing software, then LR is not what you want.
