Remus refuses to be photographed, he's the one who always takes the pictures, who always ducks out of group photos and covers his face when he sees a camera pointed at him, their freinds only have a few photos of him combined.
But Sirius has books and books of sketches and paintings of Remus; close ups of his eye, the particular curl of his hair, the freckels on his cheeks and shoulders. Him drinking coffee, reading a book, half asleep on the train. Studies of his fingers, his nose, his lips. Through Sirius' pencil, Remus is the most depicted man ever.
