Great explanation 😁

thank you, but let me quest, the aperture of 22 and 36 wolud be bether underwater, but it apertures usually cause chromatic aberration, how is this? Thaks

Hey Peru Photo, chromatic aberration at apertures like f/22 and f/36 happens because of the dispersion of light rays passing through your lens. The opening that light has to pass through at these higher apertures is considerably smaller than, for example, f/8. This causes the light rays to pass through at different rates based on their wavelength. There is a lot of physics at play here, and much more in-depth, scientific explanation out there if you want to learn more. If you want a quick solution to clean up some old photos or for the future, we suggest checking out Adobe Lightroom’s “Remove chromatic aberration” tool.
