Title: Mystery spot on clouds
Post by: Flookie on February 07, 2017, 09:13:50 PM
My knowledge of film and photography are minimal so I wasn't able to provide an epxlanation when somebody come up with this video and a frame taken from it:

At about 2:28 there's a yellow spot appears "under" the sun on the clouds and this guy is claiming it means the sun is close to the clouds. I wouldn't expect to get such a well-defined spot if it really was but I can't think of what would cause it (other than the video being doctored). What am I missing?

It's a reflection from a body of water not a hot spot on the clouds. Plus the other nonsense about convex and concave as the camera rocks, is a feature of aberration from a poor quality camera lens.

Thanks. Why yellow - is it a matter of what wavelengths have been absorbed by the water in the lake and clouds?

Most likely the atmosphere. Rayleigh scattering preferentially acts on shorter wavelengths, which is why the daytime sky is blue and sunsets are yellow/orange/red because the blue has been scattered out of the direct path.
