and a plastic bag and a tripod. Why? The bag is to protect the camera from moisture and the tripod is to protect the image from blur. Remember: Snow streaks help any subject but only if they show movement in the image. Let snow (or rain) streak out by shooting no longer than 1/30th of a second. It takes at least that long for them to show up in the scene. Since you’re outside, wouldn’t it be a shame to have the snow be a no show? One other thing to remember: use exposure compensation (+/-) to add light to the scene. You will find this control in either a button or possibly in a menu setting. The small dots in the scale = .03 (one-third) of an f stop. Move the scale indicator to the + to add light. About 1 to 1.5 stops should keep the snow white. If that setting doesn’t help to keep Snow White, ask a dwarf.
