Shots that are taken with the subject looking up at the camera show the person in a vulnerable state. You may also want straight on shots, you kneeling with some sort of gag in your mouth, or rope around your wrists. Aside from the kink aspect, take shots of you bending toward the camera, as it will highlight your cleavage and face, and then take some bent over away from the camera looking back at it over your shoulder. This highlights your hips and waist, presenting a butt to be spanked.
