Okay, it is a little primitive, but it's the easiest way I know to illustrate why the Sun's light gets warmer as its angle in the sky is reduced. When straight overhead, the light rays from the Sun travel through much less atmosphere than when the Sun is on the horizon.
This is the primary reason that both the Sun's intensity and color are affected by the ...

The color of sunlight reaching the surface changes based on the thickness and quality (in terms of things like particulate matter and water vapor suspended in it) of the air it passes through. Whether the sun is at an angle 30º above the horizon because it is noon in winter at a high latitude or because it is 4 p.m. in the tropics doesn't make much ...

The most significant difference is the dynamic range required to capture the sun areas and the shadow areas. The colour temperature you always have to manage, no matter what, but the dynamic range can be hard to manage, because the light in e.g. California vs Denmark can be the difference between being too hard without shooting HDR in California, vs being ...

Latitude doesn't directly change the sun's light in any way. The angle of the sunlight and the amount of atmosphere it has to pass through both indirectly impact the intensity and color of the light, but this shouldn't have a significant impact on taking photos as long as you properly meter and white balance.
The bigger direct concern would be the angle of ...

Ok, here are the answers to your questions one by one
1) There is a change on the color or white balance or gamma or something taking one shot for example at tropic, at equator and pole, BECAUSE the light from sun changes in every latitude?
Yes, absolutely, but the difference is not more substantial than the difference between seasons or time of day.
2) ...

You're right to a degree. If you consider only one of the cells of the grid, there is less source light available to be projected onto the target — the target "sees" a much smaller part of the light source through each of the cells if the cell diameter is smaller. At the same time, though, you are increasing the number of cells visible at the centre of the ...

Yes, with the black straws, it is going to absorb most of the light that does not go directly through the straws. The smaller in diameter the straws, the more direct the light has to be traveling to get through and the more light will be absorbed.
If the straws were white, it would actually get brighter as the reflected light would be more focused, but it ...

There are two factors here. One is the relative brightness the other is how directional the light is. Normally, light comes from multiple sources or is highly reflected. In this case, shadows are soft or non-existent because light hits where the shadow is from other directions than the one that is blocked.
Harsh light is generally very bright and very ...

When we say "darker shadows," we're really commenting on the contrast between the bright parts and the shadows. Under harsh light, you are correct, the shadows may be just as well lit (or even brighter) than they would be under soft light. But the bright parts are so much brighter that the shadows are darker relative to the bright parts. Instead of being 3 ...

A shadow is where less light is reaching a given area, in comparison to another area. Few spots have zero light, as there is usually a reflection off of the surroundings that is contributing light. It is likely less light, but there is light.
Harsh light gives darker shadows because of the contrast (the in comparison thing). There is a much larger contrast ...
