Why is the sky bluer when shooting at super wide angle?

1. Whether the sky is blue or not has nothing to do with the angle of view, but with the scenery (or later stage), lens and accessories;

2. The first is the setting. If JPG format is used, the imaging style will be different under different settings. For example, if it is set to landscape mode, the blue saturation will be higher than that of non-landscape mode, and the sky will be blue. If the film is made in RAW format, the same principle will be applied later;

3. Assuming that the parameter settings are the same, the colors of different lenses are different, which is the so-called lens coat color, which is determined by the coating quality and process of lenses. Every lens of modern lenses is coated (not necessarily on the old lenses), and different coatings will affect the light intensity and light waves that the lenses pass through, among which light waves will affect the colors (RGB primary colors and various colors formed adjacent to them). Coatings with different processes have different colors;

4. In addition to the influence of lens coating, it is also related to whether the filter is used. For example, after using a polarizing filter, imaging can filter out most of the polarized light in the air, improve contrast and saturation, and the blue sky will become bluer;

5. The sky with super wide-angle shot is bluer and does not exist. If it exists, it must be related to one or even all of the above three contents. Assuming that the shooting parameters are the same, no filter is used, which is determined by the coating of the lens, not by the viewing angle of the lens.
