EXPOSURE TRIANGLE IN PHOTOGRAPHY

EXPOSURE TRIANGLE IN PHOTOGRAPHY

It's all about the camera's manual mode of operation. To get a perfectly exposed image you need to understand the exposure triangle well.

This is an exposure triangle that has three important terms which are related to photography that is:

a) ISO

b)SHUTTER SPEED

c)APERTURE

This exposure triangle diagram is a great reference to use when determining what settings will allow more light in and what side effects it would entail.

WHAT ARE CAMERA MODES? HOW DOES IT BE WORKS?

The camera can be used in three modes.

a) Auto Mode - In auto mode you don't have any control over the camera. It will automatically set all the parameters like iso, shutter speed, and aperture as per the scenario by itself. 

b) Aperture-priority Mode (A)- In A mode you have to set your aperture as needed and the camera will automatically set the other parameter Iso and Shutter speed on its own.

c)Shutter-priority Mode (S)- In S mode you have to set your shutter speed as needed and the camera will automatically set the other parameter Iso and Aperture on its own.

d)Manual Mode (M)- In manual mode, you have full control on your camera to use Iso, Shutter Speed, and Aperture by your requirements your camera won't control anything.

Let Understand the Exposure triangle in detail with help of images.

In this first picture, the image is perfectly exposed. The Object has the proper amount of light to see the picture into the viewer's eyes. In this photo, we have used the following settings F/5.6 S 1/8 and ISO 800.

In the second image, the image is underexposed and the image loses the details and collected less amount of light by changing only the aperture of the camera. You can fix this by fixing the shutter speed as shown in the image above or iso in the camera as shown in the picture to get the perfectly exposed image like the first image.

CAMERA EXPOSURE METER/HOW DOES IT WORK TO GET A PERFECTLY EXPOSED IMAGE?

While changing the shutter speed, aperture, or iso in Manual mode this indicator will tell you whether the image is underexposed or overexposed. If the indicator turns to the left then your photo is underexposed whereas if it turns to the right your photo will be overexposed.

This camera exposure indicator helps you to give a perfectly exposed image. While shooting the picture always read this indicator to get a perfectly exposed image.

NOTE: This is the way to operate the camera in Manual mode. You need to do more experiments at home to master this three-parameter of the camera then I must say your photography will improve a lot.
