For my company, I edit studio shots with the apple pencil. However, I cant find an app where I can paint in a tint to certain areas of the picture. (I can in a few apps, however once you take the pencil off the screen and then put it back on, the darkness increases over the already painted area, therefore, it's pretty pointless when I just want it to be one tint darkness setting). I honestly can't find anything. They all do very similar things in slightly different ways and all look pretty amateur. I hope Adobe makes the Lightroom app closer to that of the desktop version. I would gladly pay for it too! So, What photo editing apps offer you the best and most professional editing tools?
