Typical uses for a tripod revolve around achieving a crisp image when your camera’s settings require a longer exposure. For example, let’s say you want to use a low ISO setting when photographing a static object, and additionally a tight aperture for a fuller depth of field. In that case, unless you have studio lighting with strobes or continuous lamps, you have to employ a tripod. Simply put you can’t hold a camera still enough for a sharp image and a long exposure. The blurring may be apparent, or only show up after reviewing images on a computer, but it’s going to be there.
