Why are light levels an issue and how do I resolve them?

The Earth's axis is tilted at approximately 23.5 degrees. This tilt, or obliquity, is the main reason for the changing seasons. But it also effects how light hits the earth, depending on where you are located.

The Earth's tilt affects sunlight around the globe in two main ways: the angle of the sun's rays and the length of daylight hours.

Angle of Sunlight

As the Earth orbits the Sun, the tilt of its axis means that different parts of the planet receive sunlight at a different angle.

• Direct Rays: The hemisphere tilted toward the Sun receives more direct, concentrated sunlight. This is because the sun's rays hit the surface at a steeper angle, closer to 90 degrees. This concentrates the solar energy over a smaller area, leading to warmer temperatures and summer.
• Indirect Rays: The hemisphere tilted away from the Sun receives sunlight at a shallower, more spread-out angle. The same amount of solar energy is distributed over a larger area, making the energy less intense and leading to cooler temperatures and winter.

This effect is most pronounced at the poles, which receive very indirect sunlight, and least pronounced at the equator, where the sun's rays are consistently direct.

How we resolve this is by using a different camera with a different sensor. The cameras look identical but one uses a global shutter while the other has a rolling shutter. Depending on where you are will depend on which camera we send you, but if there's issues, we may try sending you the opposite. This can get complex and lead down a rabbit hole, so for more information reach out to us.
