Various lights of Photography
If you want to use natural light in your photography, it's important to understand the angle of
the sun and how that will affect your composition. For example, for most of the day, the sun is
directly overtop so your subject will be lit from above. A sunny day without clouds will result in
more intense shadows, while a sky full of clouds will diffuse the sunlight so that the contrast of
light on your subject is less harsh.
For natural lighting that is softer, you may want to make use of the hours closest to sunrise and
sunset, when the sun will be off to a slight angle as opposed to directly above your subject, and
the brightness of the sun may be less extreme.
Front light occurs when the light source is directly in front of your subject. Since the light is not
at an angle, this can result in a limited amount of shadows. The light will be spread evenly
across the photo, with no section more or less exposed than the rest.
Flat light can be good for portraits, especially if your subject has wrinkles or blemishes that they
want to de-emphasize. However, if you are attempting to create a portrait that shows a lot of
personality, front lighting will not provide the detail you need in order to bring the subject's
character to life.
Another benefit of using front lighting is if you are exploring symmetry photography, as the lack
of shadows helps to make both sides of the face appear more symmetrical.
Backlight
Backlit photos are when the light source is behind the subject, with the subject in between the
light and your camera. This can be a great opportunity to play with silhouette and long shadows
in your photography. The potential downside to backlit photos is that the white balance will be
off, resulting in a loss of detail in your subject. This works well for silhouettes, but if you still
want to see some detail on your subject, this is the time to pull out your light diffuser to reflect
some of the light from the background onto the front of the subject.
Soft Light
Soft lighting occurs when your light source is diffused, so that the effect is more subtle than it
would be with a direct source of light. By using soft light, you will end up with less intense
shadows, if any at all, and a lower contrast between the darks and lights in your photo.
If you are working in a photography studio, you can use a diffusion panel between the light
source and your subject. This could even be a light-colored curtain over the window to diffuse
the natural sunlight coming in. If you are shooting outside, soft light will occur naturally on an
overcast day, as the clouds in the sky diffuse the direct light from the sun. By keeping the light
soft, you can achieve a more youthful appearance in your portrait photography.
Hard Light
The opposite of soft or diffused light, hard lighting is when your light source is pointed directly
at your subject. It results in high contrast and intensity, bright whites and dark shadow, and is
often created by making use of the midday sun. You can also manufacture this type of light in
your studio by using a spotlight or other source of light that is not diffused.
