Seriously, aren't these two terms to refer to the same thing? Or are they different? If they are the same, why do we use different terms?

Why Does The Photography World Call It An 'Aperture' While We Call It An 'iRis'?
Brian Karas
Aug 04, 2016Technically, an aperture is an opening. An iris is a mechanical structure than can be adjusted to alter the size of an aperture.
They relate to the same thing in cameras, the amount of light passing through the lens, but refer to two different things.

Aug 04, 2016Still an interesting observation, as the term aperture isn't used widely in Security for some reason.
Another one: The difference between wide dynamic range (WDR) and high dynamic range (HDR) processing.
They accomplish the same thing, however the difference seems to be that WDR refers specifically to real-time hardware processing to accomplish what happens in software post-processing for photography.
Blurring that tidy definition is my Android phone that does HDR processing on the same hardware as the camera, as soon as I take a picture, however ultimately it is still a software post-processing event.

Aug 04, 2016...WDR refers specifically to real-time hardware processing to accomplish what happens in software post-processing for photography.
True WDR cheats a little though, since its basically taking two pictures at different exposures and making a single one by eliminating the over and under exposed portions of either.

Aug 04, 2016Visual aid to Brian's excellent description.
The black is the iris, the hole is the aperture.
