White can be tough. You have to be VERY careful with any white background. Now that we finally have snow I’ll be able to give some more tips on photographing in the snow. First thing to do is to check your camera manual. Pull it out. Read it. I know but you’ll be glad you did. Find out how to manually change settings. Your camera in auto mode will choose all of it’s settings by the overall amount of light. If you are photographing in the snow it will underexpose everything because it thinks there is tons of light. The bright white snow does give off some light but it doesn’t give off enough to compensate for what your camera does in automatic mode.
Here’s a non-snowy white background example. I love this picture of Nicole!
