If you are a beginner in photography scene and don’t understand all the markings on your camera but want to get a basic understanding of how aperture, shutter speed and ISO affect your photos. Which is quite confusing.
The chart doesn’t go into great detail and doesn’t explain why someone might use a higher ISO, or how distance and the speed of a moving object impacts focus; but it does open up new concepts to beginners like depth of field, noise and motion blur. This chart will keep the things simple and easy for us to understand.
It’s also best not to treat the numbers and associated ‘outcomes’ as absolutes as the quality of the lens/camera as well as the environment you are shooting in can affect your results.
