Lens aperture is so much more than a hole in your lens that lets light
in – it’s also one of the most creative camera controls at your disposal
10 PRO WAYS TO USE
The main technical aspect of photography is
capturing a well-exposed image, though given
the levels of technology digital cameras now
boast, it’s not exactly difficult these days. But
the two main controls you use to make that
exposure happen – the lens aperture and
shutter speed – also perform other tasks thathave a big influence on the success of every
photo you take, so understanding what they
do and how they do it is crucial.
The main role of the lens aperture is to
control the flow of light through the lens to
the camera’s sensor, which it does using a
series of f-numbers – the smaller the aperture,the bigger the f-number and the less light is
admitted (you already knew that, of course).
But those f-numbers also control how much,
or how little, of the scene or subject will be
recorded in focus, so when you use your lens
apertures creatively as well as technically you
can achieve some amazing effects.aperture
