... I just play one on TV.
Or in my head.
Anyway, "white balance" is a concept that I don't fully understand, but it's easy to see the effect if you play with your digital camera's settings and take pictures of the same thing using different settings. I was playing with my tiny little Nikon Coolpix 5600 camera and took two pictures that show just how much difference your white balance setting can make.
Here's my bedroom lamp. It's loaded with three light bulbs that are (supposedly) slightly bluish compared to normal lightbulbs. The manufacturer claims that this slight bluish tint makes everything look more pleasing to the eye.
Here's the lamp with white balance set to "daylight", which, as you would imagine, is supposed to be used when shooting in sunlight.
Here's the lamp with white balance set to "incandescent" (self-explanatory, no?).
The funny thing is, in both of these pictures, the light doesn't look anything like it does in real life. The real light is somewhere between these two extremes.
Huh. I guess that just serves to remind me that this is a cheap point-and-shoot camera. (Which is exactly what I got it for, anyway.)
