Portraits – Gravity

Since we just talked about Perspective in our last post, perhaps it is a good time to discuss some ways of using gravity to our advantage and slowing our shutter speed.

Yeah, that is right. Using gravity can slow your shutter speed. Allow me to explain. As a photographer, I had some ideas of how other professional had created some amazing shots of hair seeming to float in mid-air, but without having been at the photo shoot I could not be certain and I was almost convinced that speaking with the photographer was as impossible as being at the photo shoot.

For instance, imagine a model who is demonstrating the effects of a hair product for a public relations campaign for the company. The point of the company is not to prove their product’s ability to hold their customer’s hair in mid-air but the soft and static-free beauty of the hair. How can that be demonstrated in a photograph?

First we should discuss using gravity to our advantage. Fast shutter speeds mean that we need to open up our aperture and raise our ISO thus dropping out quality a bit and losing our ability to keep the face in focus at the same time as the hair. Sacrificing quality for speed in this case is not acceptable.

Using an evenly lit and solid color background makes it worlds easier when editing the shot in the post-production process so lay down a sheet of bright white paper on the floor keeping it clean for the model.

Mount your camera above the bright white paper and pose the model on the bright white paper, making sure her hair falls in a natural looking direction giving the illusion that gravity is pulling her hair down but also giving a light “silky” appearance that you see in advertisements. Using your studio lights to over expose the background while properly lighting the model’s face will give you the flexibility you seek without sacrificing quality for speed.
