Above is the edited image and the unedited image.
This was taken with the iPhone 15 Pro Max on December 2, 2023 at 4:28 PM facing west towards the mountains.
The image is 4032 x 3024 px, ISO 50, 120mm equivalent telephoto lens with f 2.8.
The atmosphere was stable because there are large flat layers of clouds and clear skies.
The types of clouds present are most likely cumulus because of their puffines and stratus because of their low level wispiness.
