==Meter indication in EV==

Some [[light meter]]s (e.g., Pentax [[spot meter]]s) indicate directly in EV at ISO 100. Some other meters, especially digital models, can indicate EV for the selected ISO speed. In most cases, this difference is irrelevant; with the Pentax meters, camera settings usually are determined using the exposure calculator, and most digital meters directly display shutter speeds and f-numbers.

Recently, articles on many web sites have used ''[[light value]]'' (LV) to denote EV at ISO 100. However, this term does not derive from a standards body, and has had several conflicting definitions.
