Portrait Photography is one of the most challenging arts if you are considering becoming a professional in this. If you don't have a photo studio, then you can always start by concentrating on environmental portraits through which you can show the subject as well as his surroundings. The best work is the one that can produce an enlarged image of the size 11x14 inches. If the image is any smaller than this then the subject's face will look too small. You will require the help of a low ISO setting, prime lenses, a tripod, and a mid-range digital SLR.

There are two basic elements for portrait photography in a photo studio. The first one is a controlled background. You will have to focus all your attention on the subject and at the same time minimize or remove the distracting elements in the frame. A common mistake made by many portrait photographers is the use of seamless paper or various monochromatic backgrounds. What you need to understand is that you don't require a special room to create a controlled background. There are various types of clever portable backdrops and backdrop supports, which you can build or even buy. Inspite of all this, if you are still unable to control the background, then the next best thing is to use a long fast lens like a 300/2.8. A fast telephoto lens will have very little depth of field and hence the eyes and the nose of your subject will be sharp. The distraction in the frame will become a blurry blob of colors.

The second most important element of a portrait studio is controlled lighting. If you have lights kept on stands or if you can hang them from the ceiling then it will be easier to pick the angle at which light will strike the subject. The use of umbrellas and various diffusion equipments will help you to pick the harshness of the shadows on your subject. Backgrounds have always played an important role bringing out the details in a portrait photograph. So if you can’t find a big open space with diffuse light and a neutral background then you will have to steal one

Here are some key factors of portrait photography. The first one is:

Lighting
The best lighting condition for portraits is soft and off-camera. If you have a large north-facing window or the soft-box then it will work very well. For shooting outdoors, an overcast day or sky will provide a perfect lighting condition. If there’s sun outside then you can use an electronic flash or a reflector to fill in shadows underneath the eyes.

Lens
The best way to flatter your subject is by de-emphasizing the nose. This means that you will have to stand at least 10 feet away from your subject. The problem that arises in this case is filling your frame with the subject's face since you are standing at 10 feet. To deal with this problem, you will require a high magnification or telephoto lens. Typical portrait lenses vary between 90 and 135 millimeters long for 35mm cameras.
