What the heck is Aperture ??

mengenal aperture

In photography, the lens aperture functions like the iris of the human eye. Opening and closing to adapt changing light levels. The aperture opens wide to admit more light in low-light situations and closes down to a pinhole when the light gets bright.

With oder cameras , the photographer often had to adjust the aperture setting manually for each shot. However , modern , auto-exposure , digital cameras typically set the aperture automatically to produce the correct exposure as indicated by the cameras built in light meter. But just because we dont have to actively manipulate aperture values doesnt mean that we should ignore the aperture component of your exposures completely.
