ON1 Photo Raw is a photographer’s delight. The software application could be used as a raw processor and also as a basic editing workflow tool. Also, it could be used as a plugin or standalone application within other editing apps – for instance, Lightroom. The app comprises different modules to play and fiddle with your images: develop, effects, layers, and resize. ON1 Photo Raw may not offer an obvious benefit over other similar photo editing apps such as Lightroom, but it would certainly give them a run for their money.
