Figuring out what she wants to do and how she wants to get it done, in post-processing doesn't have to be frustration. It can be enjoyable to play around, experiment, and see how things work and how they behave. It can be meditative to clearly envision in her head what she wants to do, with a picture. It cna be a fun and challenging puzzle to figure out how to get her picture from where it is now, to where she wants it to be.
