The Basic Principles Of Digital Photography Lighting
Digital photography lighting is made up from several areas, such as frontal
lighting, side lighting, back lighting, hard and soft light and contrast.
I'll start with light direction. You can watch and learn more about
these topics in the video below.
Frontal lighting is created when your
light source is coming from behind the camera. It shines onto the front
of your subject. If you were taking a
portrait, the subject’s face would be evenly lit. In this case,
contrast is easily manageable and getting the right exposure is
straight-forward.
The only disadvantage, in this case, with portrait shots is that your
subject may be forced to squint.
Side lighting for most types of shot is a
far better option. By keeping your lighting to one side of the camera,
you can make shadows rake across the scene. This will highlight
textures in all but the flattest surfaces, emphasising form and adding
a strong sense of depth to your shots.
Back lighting can be a problem if you
don’t set your camera for the correct exposure. You can end up with
your subject as a silhouette with a bright background.
On the other hand, it can be used to create stunning results. You could
have your subject correctly exposed in the foreground and the
background burns out to create an atmospheric high-key effect.
If you have to shoot into the light, try using flash-fill to light up
your subject so it doesn’t appear as a silhouette.
Digital Photography Lighting - Hard or Soft Light, Which Is
Best?
Hard or harsh light is generally created
by a single and small source. A good example is the Sun. On a clear
summer’s day it casts dense black shadows. Colours seem intense,
although colour saturation is actually greater in slightly overcast
weather.
Soft light is used when you want to add
atmosphere and romance to your portraits, landscapes, etc. The absence
of strong shadows allows you to capture every detail. The results are
much more soothing to look at.
Hard light can be made to look much softer by placing some kind of
material between the source and the subject so it is diffused over a
wider area.
When you are shooting outside, clouds are great for diffusing hard
light from the Sun. They act like a giant softbox, causing the light to
soften.
Taking pictures indoors is a different story. You have full control
over your environment. You can bounce light of walls, use reflectors
and condition the lighting with softboxes or umbrellas.
What is Contrast?
The variation in light is important in digital photography because it
determines the contrast level of a particular scene. The contrast is
roughly defined as the difference in brightness between the highlights
and the shadows in your picture.
