Annotating a screenshot is faster than rebuilding the state in a design tool, and more honest: you’re working from the actual thing rather than a representation of it. [[Save screenshots]] is what makes this a practice rather than a one-off, because the annotation only works if you have material to annotate. Mark what needs to change, why, and where. The roughness of the annotation communicates that this is feedback, not a direction.
That roughness matters. A precise redline suggests a decision has been made. A scribble over a screenshot suggests a question is being asked, which is closer to what most feedback is. [[Fat-marker method]] uses imprecision in the same way: as a signal that the conversation is still open.
