I found it best to show high fidelity wireframes to clients. It makes it easier for the client to understand what I’m presenting. The only time I have some low fidelity frames is when I am doing it on paper or during a meeting with client on the white board talking through things
Saying these aren’t real is silly. Of course these are real. I found these to be the final versions being sent to visual designer to begin working on or to get approval from client.
