The Photography Triangle is very important in photography. The elements of photography triangle work together in controlling the incoming light towards the camera sensor. If you master how to set each of photography triangle elements in a location with a certain condition of light volume, you will certainly be able to produce classy and creative photographic results. Photography Triangle is also called as Exposure Triangle. To improve your photography skills, firstly you need to understand exposure triangle and its elements (aperture, ISO, and shutter speed). So, how about exposure stops? What is Stop in Photography? Here you are going to discover the understanding of Exposure Stops in photography.
The Definition of Exposure Stops in Photography
Stops in Photography refer to changing the amount of light received by the camera sensor or film which then affecting the exposure of a photo. Increasing one stop means aiming to get a two times lighter photo. Reducing one stop means aiming to get a half times darker photo result. So, each stop in photography is worth two times of the light volume.
The amount of light received by the camera sensor is named as exposure. So, increasing one stop means to increase the exposure two times. You can raise or reduce the exposure by changing one or a combination of the three exposure elements.
To illustrate the stop in photography, assume that your room has 4 lamps at 100-watt each, and all of them are turned on. Because the stop in photography is the change of light or dark, so reduce one stop means you get 2 lights off in the room. Means you let only two lights on. While adding one stop means you have to bring and turn 4 lamps on with the same wattage. In this illustration, the room likens a camera sensor, while the lamps liken the camera exposure.
Shutter Speed Stops
The shutter speed of a camera measures how long the camera sensor receives the light. The longer it receives the light means the more light is received by the sensor. It means raising the exposure. In the shutter speed, a full stop is easy to remember because it’s the result of the division of two figures (rounding): 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, and so on. Move one stop means to jump once, e.g. from 1/30 to 1/125. Moving two stop means jump twice. To understand more about the sequence learn more about camera shutter speed.
The calculation of the exposure stops on the shutter speed is also the same with ISO. If you raise one stop it means the ISO value is multiplied by two. For example, increasing the ISO one stop means it jumps from ISO 100 to ISO 200, ISO 200 to 400 and so on. To understand more about the sequence learn more about camera ISO speed.
In aperture, the stop figuring is somewhat different to the other two exposure elements. The stop values sequence in aperture is loping: f/1, f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, and so on. To understand more about the sequence learn more about camera aperture.
What is the Connection between the Stop and all of the Exposure Triangle Elements?
Briefly, let’s say you use the initial settings of your camera exposure at 1/125, f/8, and ISO 100. As the photograph under a dark exposure, you raise it one stop which means it can be one of these three settings: 1/60, f/8, and ISO 100 (if only changing the shutter speed). Or, it would be at 1/125, f/5.6, and ISO 100 (if only changing the aperture). The other one is at 1/125, f/8, and ISO 200 (if only changing the ISO speed). All of those changes are worth one stop.
