Light shaping tools & light meter


Here I will show you some of the different light shaping tools that you can find in the market and the function of a light meter.







Different kind of light shaping tools can give you different kind of effects. Some of the light shaping tools that can be found in the market is shown below:

The next important tool which you need when using studio lighting is the light meter. A light meter is a device used to measure the amount of light. It can be used to determine the proper exposure for a photographer. Typically a light meter will include a computer (analog or digital), which allows you the photographer to determine which shutter speed and f- number should be used for the best exposure, given a certain lighting situation and film speed.


A light meter can be used to measure incident and reflected light. A camera metering system only measures reflected light. A light meter can be set to Shutter priority or Aperture priority just like your camera. When shutter priority is used, at a given ISO, the light meter will measure the corresponding aperture. Usually we fix the shutter speed and find the appropriate f-number and ISO. Why??? This is because we would want to optimise our flash sync speed. Some of your camera can sync with the flash up to 1/250 shutter speed.
