A good part of the U.S. has snow and lots of it at the moment, I know we do here in New England, and have even heard friends talk about it down in Texas this year, Houston no less, amazing.   I therefore thought it would be a good time to remind folks the main trick to photographing snow. All the white everywhere bounces and reflects light, rather well, and although this is a good thing for picture taking, it most often fools your camera's light-reading mechanisim.  When photographing snow you will often need to deliberately overexpose the image by a bit. Light meters try to find a neutral mid-range of light. Snow tricks the camera into thinking it doesn't need as much light and the resulting images are dull and have a gray tinge to the snow. Slightly overexposing the image corrects this (the exact amount of overexposure needed will vary depending on how much snow is in the composure) and results in a bright white snow and proper exposure on other items in the scene.  For those of you, well--most of you, shooting with point and shoots, this is not as simple as someone with a DSLR.  However, there are adjustments, and depending on how well you know them, it shouldn't be that difficult to create settings that essentially fool the camera right back into making the proper exposure.  Again, it's an overexposure, slight, that you're looking for; so that means opening the aperture a stop or two, or-conversely, slowing the shutter speed down an equal amount, instead (not both at the same time).
