Exposure Meters

Many people think that physical light meters (exposure meters) are not necessary any more due to the majority of DSLR cameras come with a built in light meter. However, there are numerous situations where a light meter becomes useful. For example, when lighting a green screen, you can use it to make sure the lighting is evenly across and that there is no hot spots or shadows. In contrast, it can also tell you the difference between shadows and highlights, in case you don't want the even lighting. It also tells you what F/ lighting you will need. Most meters have three readings, incident, reflective and your flash. Incident is the light that falls on to your object and reflective is the light in which is reflected off of your subject. However, the most popular reading is incident.
