In an attempt to get a picture of all the cousins, on my husband's side, we took a birth order picture. Each cousin held a sign representing when they entered the family.
I loved the concept but had to resort to using the house lights (tungsten light) and a flash. Gasp, I know. The result, the picture has more yellow tones to it.
On our ride home, I figured out how to fix it. I discovered if you take your camera off of automatic, you can set the white balance.
My camera was set on AWB (automatic white balance) for the birth order picture I took. So, the camera decided what it thought represented 'white' the best. BUT, if you take it off of AWB, you can tell tell your camera what kind of light you are shooting in. Had I selected tungsten light, I could have corrected the color cast and my picture would not have looked as yellow.
You'll also want to set your camera to AV (the aperture mode).
Then, set the ISO speed to the highest setting (I pushed mine to 1600). Set your aperture to the lowest setting (I set mine to F4.5). Your camera should have a dial, mine is near the shutter release button (the button you press to take your pictures), that dial will allow you to change your settings.
Ready to see the difference?
Taking a picture using only house lighting (tungsten lighting), leaving your camera on the automatic setting, using no flash, your picture will look something like this.
Taking your camera off of the automatic setting, setting your ISO to the highest setting, your aperture to the lowest and setting the white balance to tungsten lighting (all as described above), the color cast will be removed from your photo and the result should look something like this.
Can you believe the difference?
