Back Light is when you use light that is behind your subject to illuminate it.
It’s really pretty and I love using it!
I was at a wedding recently in Pala, CA and snapped this sunset back lit photo.
50mm lens, ISO 100, f/5.6, 1/160 sec
There are a few things to keep in mind when you want to achieve this look:
1. Make sure the light is coming from BEHIND the subject.
2. Shoot at a low ISO. ISO is your camera’s sensitivity to light. When you use back light, you have LOTS of light coming directly at you. For something like this, I usually set it to ISO 100.
3. Use manual focus. With all the brightness that is going on, your camera will probably have a hard time with auto focus. Use manual focus.
4. Overexpose. If you listen to your camera’s meter when using with back light (i.e. you are shooting in Auto mode), more times than not, it will make your subject too shadowy and dark. If this is the case, overexpose as needed. Overexpose means to make the photo brighter, so slow the shutter speed or open up the Aperture. This is how you achieve that dreamy, glowy look.
