thanks all for you wonderful replies and taking your time to help me. Greatly appreciated.
I understand how masks work, and are checking out wheter AP can replace PS for me. However, when testing out the trial back in November. I sort of hit the wall with the foreground to transparent gradient workflow from PS. I know there are many other ways of achiveing the same result, both in PS and AF. But using this gradient, insted of a brush, is my preferred way. But I does not seem to be able to replace this exact workflow in AF. But I might switch over all the same though, but that is another story.
Here is a video of me showing what I am doing in PS.
