TYPES OF BACK LIGHTING
Just like any other lighting scenario, back lighting has it’s quirks and can give you completely different looks depending on how you control it. Below are a few of the different looks that tend utilize the most.
Shooting back lit in soft light tends to deliver a calmer, more intimate image. If you are just looking for that simple soft light, wait until the sun is just below the horizon or hidden by something else (trees, mountains, buildings, etc.) and shoot with your subject completely in the shade. That will give you a soft luminous light that envelops your subject.
Haze is one of the more versatile looks you can use with back lighting as you can manipulate it to bring out a soft summer glow in a lifestyle image, or you can make it a bit stronger for a completely different look that might fit a harder editorial. If you are looking for a soft hazy glow to come across your image, shoot when the sun is still in the sky (not hidden by mountains or under the horizon), and have the sun hidden just outside of the frame. This will allow some of the stray light to sneak into the side of your frame leaving a soft wash of light and color across your frame. If you are looking for a harsher haze with more flares and light artifacts, allow the sun to shine directly into your lens (longer lenses work best for this) and you will find a haze that has a bit more substance to it.
Having streaks of light coming into your frame is a great way to add dynamic energy into your image. To create rays in your frame, your best bet is to shoot with a wider lens which will stretch the light a bit and leave it streaking across the frame. Instead of hiding the sun just outside of the frame or behind something in the frame, allow it to peek in. Whether it is peeking out from behind something in the image, or peeking in from the outside of the frame, make sure that there is a little sliver of direct sunlight hitting your lens. This little sliver is what will create your rays. Also, the more you stop down your aperture, the more defined your rays will become.
