Taking control of your camera step by step Part 5

Setting White Balance

Where ISO deals with the amount of light, White Balance deals with the color of light. The part of the brain that processes the information from our eyes does an excellent job of “white balancing” the light we see. We can walk from outdoors (daylight) to an office building illuminated by fluorescent lights and then into an office illuminated by tungsten bulbs and our eyes will adjust automatically. You may get a glimpse of the green colorcast from the florescent lighting or the orange colorcast from the tungsten but your brain corrects for those color casts in an instant.

Your camera makes similar adjustments when it is set to Auto White Balance, and the newer cameras do a great job. But relying on Auto anything is what we are trying to get away from. Your camera has several white balance settings to get you in the ball park. These settings will be better than Auto when there is a color cast around that can fool the camera. When light hits an object it will reflect the color of that object back into the scene creating a color cast. For instance when you are making images in a room with brightly colored walls the light that hits those walls will reflect that color back into the room. The most precise white balance adjustment you can make is creating a Custom White Balance for what ever you are photographing.

Creating a Custom White Balance is not difficult but it takes a few steps if your camera has this option. Check your owners manuel for the specific steps you need to follow for your camera. You will need a “target” that is either middle grey or white. Once you have your camera setup to create a custom white balance, you put your target in the scene being sure to fill the frame with the target. You then trip the shutter and the camera tells you if you were successful. Now your white balance is set for those lighting conditions and only those conditions. When the lighting changes you need to create a new custom white balance.

  1. Vincent, thanks for clearing up White Balance. I have been winging it since I purchased my first DSLR! I was never one to use the Auto functions on my Canon. I never got the results I wanted so I have always utilized the advance funtions. I want to thank you for sharing this series. It’s taught me a things that probably should already know!

    Thanks,
