Aeksehu square law?
1- match the intensity of radiation directly proportional to the square of the distance
2- X-ray intensity is inversely proportional to the square of the distance
3- commensurate force directly proportional to the square of the X-ray distance
4- X-ray power is inversely proportional to the square of the distance.

Today we discuss a topic that our follower forgot us in a comment he made on YouTube in the video of another vlog.
We don't get tired of saying it, your suggestions are always interesting and they help us a lot, so if there is any topic you want us to talk about, don't stop telling us.
Let's go with the subject.
Today we talk about the law of the inverse of the square or the law of the inverse square of distance, which has a somewhat long name, but it is very easy to understand and its knowledge will help us to master and better understand lighting.
This law refers to those undulating physical phenomena, such as light and sound, whose intensity decreases inversely proportional to the square of the distance from the center where it originates.
How can I apply this in photography?
Well, in many ways, although we are going to talk about the most common: about flash lighting.
- The law tells us that when we want to take a flash photo of a person who is located half a meter away from the flash, the light will come with an intensity A.
- But if we include another person in the frame, located half a meter from the first person, that is to say one meter from the flash, the light that would arrive would do so with an intensity four times lower, not with half the intensity as we might think by boat soon.
- That is, the first person would be perfectly illuminated and the second person perfectly ... in the shade.
Whenever we illuminate artificially, we must take this into account, because ignorance of this peculiarity of light can ruin many photos and the solution is not in the camera, but where we place it.
We can draw several conclusions:
- If you have to take pictures of groups of people and only have the camera flash, keep in mind that the distance between the camera and the first person in the group must be greater than the distance between the two people furthest from the group, taking as reference the flash.
- The same principle serves to illuminate people before a background.
- If we take pictures of a single person, we must bear in mind that if the flash is on the camera, the head will receive much more light than the rest of the body.
One solution may be to work with the camera's off-center flash (in the case of wanting hard light) or bounce the flash light, thus matching distance relationships and softening the light.
