What is Exposure:-xplained

Camera dial
In digital cameras, exposure means the amount of light enters in the camera that reaches the camera sensor to make an image. When you turn off your Auto mode and use manual mode this is very important to know how the things work. Now the question is how light enters in the camera and how it can be controlled.

Following are the three things responsible for the exposure.

Aperture (f-stops)-Size of the opening of the lens, through which light enters in the camera
Shutter speed-Duration of the time that shutter is open
ISO-Sensor sensitivity to the Light.

You can control these features to control the amount of light enters in your camera. To control exposure (Shutter speed, Aperture, and ISO) and set the right exposure for your camera is not easy, the only thing you can do is practice, practice, and practice. We have to continuously increase and decrease the numbers until we get the right exposure. If you allow more light to enter the camera, the image can be overexposed or if allow less light to enter the image can be underexposed but you can also use this feature to show some creativity (we’ll discuss this in our later post).I found this book Basic Studio Lighting: The Photographer's Complete Guide to Professional Techniques very helpful for the lightning tutorial. In this book, you can master the lighting techniques step by step and learn the control over Shutter speed, Aperture, and ISO. Tell us how we can improve this article or what more expect from ABA Creation
