LENS HOOD | ALL YOU NEED TO KNOW
"Light gives and light takes away." No, suddenly I haven't decided to preach anything to you about religion. This is how I think light works in conjunction with photography. Light is capable of building an image, but it can also be the reason for its destruction. If you think about it carefully, all the basics of photography (aperture, shutter speed, ISO) are actually means of measuring and filtering light, so that only the right amount reaches the actual image sensor.
That's all it is. Yes, everyone uses different methods to do their job, but what a photographer essentially does is "shape" the light in a particular way so that the desired effect is achieved in the final frame. In this case of the humble Lens Hood, this principle still remains and is the same. Chackout for more detail Techmong.com click here.
What is a lens hood?
Before answering this question, I would like to ask you a cross-question. What is a hood? As in clothing. Do you know the one people wear, which is often attached to the back of their sweatshirts?

It is a small piece of fabric attached around the collar of the jacket that, when unfolded, is capable of covering the head of the person who wears it and provides additional protection against wind, sun, cold and rain. That it also serves as a comfortable pillow is just a happy accident.
The lens hood does EXACTLY the same thing, only for lenses.
A lens hood is generally a small circular black piece of plastic (conical or petal-shaped) that can be attached to the front of a lens for added protection against scattered light rays that can damage the image.
LET ME ELABORATE
Try to remember your last trip to the beach. It's windy, it's sun, warm golden sand below you and lots of people around. You try to look at the water, but it is too bright. What do you do? You put a hand to your eyes and try to protect them from sunlight to create a tone for your eyes and to see better. Lens Hood performs this exact trick so your camera can see better.

If you are thinking that if all a Lens Hood does is provide shade for my lens to shoot better, can't I use my hand or a towel or a book to create a shadow for my lens? It turns out yes! You can use anything to create a shadow for your lens and that would work exactly the same if not better. But there are some problems.
First of all, if you're shooting alone without any gear like a tripod, light stands, and poles, it could be a big deal holding your camera with just one hand and shielding your camera from the sun with the other. One-handed operation of the camera can cause camera shake, blurred photos, and generally uncomfortable ease of use.
Second, just one of your hands or a book may not be good enough to protect the front of the lens element from all the scattered light rays it needs protection from. You can probably protect one side of the lens, but when you shoot something bright and uneven like water near the beach, the reflected light rays come at you from all sides. Locking them all is a difficult task for a one-handed photographer.
Third, every time you change position with respect to the light source, you must also change the strategies for shading the lens. Sometimes it can come from the left, sometimes from the right, probably from top to bottom.
Why make your life as a photographer more difficult than it already is? Use the easiest and most effective method that exists for all this. Use the damn parasol. It's easy, it's cheap (if it's not free). Set it up and forget it and it will do its job every time, while you use all your mental power on much more important things like composition and time.
PRACTICAL USES
The lens hood has all but two practical uses, but they are very important to both your images and your lenses. Are here:
PRACTICAL USE # 1
As I mentioned earlier, the first and main job of a lens hood is to isolate the front of the lens element from the scattered light rays from the light source and thus, in the process, help make a better image. Now naturally the question arises: how does a parasol contribute to a better image?
Cross section of a camera lens
Very simple. As you already know, the basics of the basic lens you use in your mirrorless or digital SLR camera have many lens elements inside. Some are convex, others concave, some have completely different shapes. When the light reflected by the subject enters the camera directly
