Cap Walk — shields up, side by side.
Cap Walk sets you walking toward the camera beside a costumed hero. In the single run shown, a bearded man in a navy suit and dark tie carries a round red, white and blue shield with a star in the middle. Next to him strides a figure in a blue star-marked suit and helmet, with large brown wings, above a smoky ruined city.
The sample
What happens in the Cap Walk sample.
At the start the suited man is in the middle of the frame, and the hero is half out of shot on the right with one wing showing. A hazy, broken city stretches out below a grey sky. Both walk forward at a steady pace. As they come closer, the hero moves fully into view, a second shield shows at his side, and the ruins give way to a pale, cloudy sky. By the end the pair fill the frame from the chest up, and both look straight into the lens.
The suited man keeps his beard, hair, navy suit, white shirt and tie from start to finish, and the shield stays at his side. The hero's costume, helmet and wings do not change either. What changes is the framing, which tightens as they walk closer. Since the sample begins on a front view of a man facing the camera, a clear, front-facing photo from the waist up is a sensible start.

Your photo
Photos that suit it.
One-tap effects have one input. The photo you pick is your creative control.
Look toward the lens
The suited man keeps his eyes on the camera as he walks, so a photo where you look straight ahead mirrors the sample.
Waist up or closer
The sample ends on a chest-up view of the man, so a clear photo that shows your face and shoulders suits that framing.
Dark, smart clothes fit
The man walks in a navy suit, white shirt and dark tie next to the bright costume. A plain, dark outfit in your photo sits close to that look.
