Photographic Exposure: Learn the Fundamentals, part II

Beginner Photographers need to have a basic understanding of the exposure triangle. Just think of the triangle as the core and essence of digital photography. In this article, we have simplified the issue for you so that you can easily grasp it and use it to click some exceptional images!

 Here is a table to further connect these elements: ISO, Shutter Speed, and Aperture. A good photographer always check whether the three elements of the exposure triangle are balanced or not

We will begin by explaining what exposure triangle really is not, and it’s not a rubber band. Photography Simplified, the Exposure Triangle is equilateral and impossible to stretch. Thus, it stabilizes the relation that exists between the three essential components of Exposure; ISO, Shutter Speed, and Aperture.

When these three components work together they create a correct exposure. Exposure triangle means these 3 elements have to work in harmony and if you adjust one, another element MUST also be altered in the opposite direction to keep the exposure the same. This is the basics hint which will take you a long way. So remember the exposure triangle is paramount and developpes a cause and effect relationship and balance between its three functions.

ISO, Shutter Speed and Aperture: let us dive in!

Make sense of ISO.

ISO is the function in digital photography which refers to the sensitivity of the camera sensor to light. Digital photographers use this system a lot. Just remember the rule, if the ISO is lower, the sensor will be less sensitive to light and if it is higher, the sensor will be more sensitive to light. So a lower ISO number will lead to a cleaner looking photograph and there will be less noise but sometimes photographers need to use a high ISO in low light conditions, or to give an artistic effect to the photograph.

TIP: ISO in AUTO is generally the variable that adjusts the triangle, but to avoid unwanted grain it is also recommended to set a maximum ISO, -let’s say ISO 800 for most of the situations – then let the camera play with all the 100 -799 other ISO possibilities.

Get to know Shutter Speed.

Shutter speed is what controls the amount of time that the camera’s shutter is open and is measured in seconds, mostly in fractions of a second. This means that it refers to the duration of time the light is allowed to hit your camera’s sensor in order to make an exposure. So if the speed is longer there will be more light and if the speed is shorter then there will be less light that hits the sensor.

TIP: If S (Shutter Speed) is the constant, -let’s say at 1/1000 for moving objects, sports, birds – then the camera chooses A (Aperture) , and ISO in AUTO is the variable that adjust the triangle.

Catch on with Aperture.

Aperture refers to the size of the lens opening whether it is large or small. The iris inside the lens controls the amount of light that can pass through it. Lens range their opening in “f-stops”. If the f-stop number is low like f/1.8 it means a larger opening, more light. When the number is high like f/22 it means a small opening, so less light.

BIG HINT: If A (Aperture) is the constant, -let’s say at f/16 for landscapes-, and ISO in AUTO is the variable, then photographers are leaving the camera to select the speed.

Putting the Three Elements Together

Remember to keep one side of the triangle constant. It’s the easiest way to understand how it works. The rule is when you alter Aperture then another element must also be changed in reverse direction. If your f-stop is widening, you should fasten the shutter speed to maintain the same exposure. Personally, I work mostly in A Mode with the ISO as low as possible. A handly tripod will help when a low speed occurs as the result.

Therefore, professionals always want to check whether the three elements of the exposure triangle are balanced. Whenever the capturing. It is not very tough to grasp and once you get a hang of them you will truly become a proficient photographer.

Wrapping it up

Now it’s your turn to go out and experiment with these findings! Apply them in real life and experience the magical change they bring about. These are the basics and if you hold on to them tightly they will surely help you master photography within no time.

Don’t waste time, begin working on your camera settings to get a perfect exposure! Take out your camera immediately! Have a great time on your photography adventure and may all of your images be exceptional!
