Updated: Aug 9

To become the best photographer you can be you must understand Aperture, Shutter Speed, and ISO. Each function goes hand in hand. All three combined is what creates your image. Sure you think what about the Auto Mode? Doesn’t this do all the work for you? Yes and no. Your camera is making an educated guess. This doesn’t mean you will get the exact shot you were looking for.


Aperture

Is the hole in the Lena that allows light to pass through the lens, into the camera body and onto the cameras sensor. Aperture is expressed by F-stop or by F-numbers. This describes how open or closed the Aperture is. Different F-stops can also be expressed with words such as wide, middle, and narrow.
