Digital Photography Basics – Uses A Light Meter To Measure Your Exposure

A light meter is a device that measures the amount of light that is reflected or emitted from any object. By knowing how much light you are working with, you will create the correct exposure for your photographs. You can usually purchase this piece of equipment at your local camera or light meter store. However, there are many things that you need to know before buying one. This article will go over a few of these things, and hopefully, by the time you are finished reading this, you will have a good idea of what you need to know when purchasing a light meter from instrumentchoice.com.au.

 

When purchasing a light meter, you should first know a bit of the technology behind them. There are three different types of light meters, which include mechanical, optical and digital. Mechanical light meters work using a spring-based mechanism and are typically entirely accurate. They use a wheel to determine how much light has been detected, and they can often be used in conjunction with a camera to create the right exposure settings.

 

The optical light meter works differently because it does not use a spring-based mechanism. Instead, it uses an internal reflector that measures the intensity of light that shines onto it. This internal reflector can determine light intensity in a completely different way than the mechanical meter can. Hence, it is essential to make sure that you buy a good brand if you are serious about taking great pictures. The last type of light meter that we are going to discuss is called the digital meter. Digital light meters from instrumentchoice.com.au use digital sensors to determine the amount of light reflected or emitted.

 

Digital light meters from instrumentchoice.com.au use a combination of photodiodes to read the amount of light that is being emitted or reflected. Then it will calculate how much light is being blocked by surfaces to determine the amount of light emitted. This meter is handy when you need to meter outdoor scenes because you can use as much light as you want and only have to take one measurement. On the other hand, the lux meter measures the level of light that is emitted from a subject.

 

The primary function of this type of meter is to determine the length of time that your aperture has been set. The shorter the aperture, the faster the shutter speed will be, and the lighter will be let into the camera for you to photograph. In essence, this setting determines the depth of field that you will see. If you are taking a shot outdoors, with lots of outdoor lighting, you want to use a fast shutter speed to maximize the depth of field. However, if there is not much outdoor lighting, you will want to slow down the shutter speed so that you can take photographs with softer backgrounds. This type of meter can also help you figure out the distance the camera can focus on a subject, depending on the shutter speed and aperture.
