Portrait Poses

There are three basic positions for someone’s head and face in a portrait.

1. Front view
2. 3/4 view
3. Profile

Expression

For family photos a smile is a must but not so for a portrait. It is however important that your subject look comfortable. It is your job as the photographer to talk with your subject and make them feel comfortable.

Focus

When shooting a portrait, the subject’s eyes must be in focus. Full stop. Period.

Portrait Lighting Styles

There are a 5 basic lighting styles for portrait photography. Each style is defined by how light falls on the face.

1. Rembrandt Light – the model is face forward, main light is at 45 degrees and casts a light on the opposite side of the face to form a triangle on the cheek.

2. Broad Light-model’s face in 3/4 view-light falls on the side of the face with the visible ear. Good for controlling the reflections on glasses.

3. Short Light-model’s face is in 3/4 view, the light falls on the side of the face with the features. (Not on the side with the visible ear.)

Both of these are examples of short light.

4. Butterfly Light, Clamshell or beauty or glamour light-model is face forward, front light.

5. Split Light-model is face forward, the main light is at 90 degrees to the camera and falls on one side of the face.

Depth of Field

Depth of Field-The distance between the nearest and farthest points that appear in acceptably sharp focus in a photograph. Depth of field can be shallow or extensive. While the term includes the word depth, depth of field refers to focus.

• 

• 

Shallow Depth of Field

Shallow depth of field is commonly used in portrait photography to separate the subject from the background and in food photography.

• 

• 

Extensive Depth of Field

Extensive depth of field is often used in landscape photography and photojournalism.

• 

• 

The depiction of space

Perspective-the representation of a 3-dimensional space on a 2-dimensional surface by converging lines, diminishing scale and/or atmospheric perspective.

Sometimes photos combine perspective and shallow depth of field.

How to control depth of field (with a camera)

These four factors control depth of field:

• lens aperture 
• focal length
• camera-to-subject distance
• sensor size.

Aperture

Aperture is the size of the opening that allows light to hit the camera’s sensor when the photograph is taken. 

1. Aperture values are expressed in numbers called f-stops. A smaller f-stop number means more light is coming into the camera and will create shallow depth of field. A larger f-stop number will let less light into the camera and create extensive depth of field.
2. The full stops for aperture are: F2, f28, f4, f5.6, f8, f11, f16, f22, f3

Focal Length  is the distance from where the light converges in the lens to the sensor. If it is a short distance then the lens is a wide angle lens and shows a lot of the scene. If it is a long distance, the lens is a telephoto lens and it magnifies the scene. Wide angle lenses create extensive depth of field while telephoto lenses create shallow depth of field.

Camera-to-subject distance is how far the subject is from the camera. If everything is far from the camera, it is easier to achieve extensive depth of field. If the main subject is very close to the camera and the background elements are far from the camera, it is easier to achieve shallow depth of field.

It is the small size of the sensor that makes cameraphones so good at achieving extensive depth of field. It is also the main reason it is so hard to get your cameraphone to achieve shallow depth of field.Sensor size-the smaller the sensor the easier it is to achieve extensive depth of field. Bigger sensors allow for shallow depth of field.

 Bokeh-Bokeh comes from the Japanese word boke (ボケ), which means “blur” or “haze”, or boke-aji, the “blur quality.” Bokeh is pronounced BOH-Kə or BOH-kay.
