Magic lessons are ongoing. They mostly involve Addy gently suggesting things to try and encouraging Aedyt to come up with things to try, at first, and then when the original scope of the power is pretty well mapped Addy starts pushing her on fine detail work and speed and editing "blind" - restoring things she hasn't seen originals of, filling in blanks with context-appropriate things regardless of whether the context makes any sense to Aedyt, doing the sorts of things photo-editing software can't actually do like remove a person to show what was behind them.
