UNIT 57: PHOTOGRAPHY- What is Aperture?

'The size of of the opening in the lens when a picture is taken'
-When  you hit the shutter release bottom of your camera a hole opens up that allows your cameras image sensor to catch a glimpse of the scene opening to capture

Aperture measure in "f-stops"/f-number

-Moving from one f-stop to the next doubles or halves the size of the amount off opening in your lens and the amount of light getting through
-Depth of field is= the amount of your shot that will be in focus
Shallow depth of field= small part in focus
Large depth of field= large part in focus

-Some styles of photography requires large depths of field (and small apertures)

Large aperture - portrait photos f2.8 to f5.6
Small aperture - landscape photos f16 to f32
