Thank you. It's relieving to know how the filter works, rather than just hearing "it just works" or "I don't know if this is magic or science"

Michael RESPECT..thank you for the videos and your work. Having purchased some of Michael's tutorials I can tell you right now they are the most valuable resource for photography enthusiasts looking to up their game a level. What I love about your public videos is that you stay away from bushing brand names and reviewing gear for the sake of click bait. Thanks bro you are awesome.

Hi, Michael - I enjoyed your video, and I found the examples with the rope to be great for visualization. I've found other videos on the web that suggest that light that is vibrating parallel with the filter is blocked - that is, it is absorbed by the filter, and probably turned into heat - while light that is vibrating at 90 degrees to the filter is not absorbed, and is thus passed. Of more importance is the fact that your video discusses linear polarization; but virtually all camera filters these days are circularly polarized. Truthfully, I do not know the difference between a linear and a circular polarizer, and I haven't heard a good discussion of it. Nor have I found a good discussion on the web. Lots of stuff on how to use them to enhance your images, but nothing at all on their construction, or what the 'circular' denotation refers to. Thanks for a good video - Charlie

Hi, Michael - I did read your update. After your comment, I also went to the wikipedia page, which I had not previously done... but I'm afraid that all Wikipedia has done is convince me that I'm utterly stupid. It would appear that inserting something called a 'quarter wave plate' after a linear polarizer causes the wave to start rotating along its axis... for reasons not stated. When you follow the link on a 'quarter wave plate' you arrive at a page that is besotted in mathematics, using mostly symbols that I have no understanding of. Ah, well. I certainly won't hold you responsible for Wikipedia. And I did find much of your video helpful. If you ever do a video on how a circular polarizer works, I'm sure it will be up to your usual high standards. I look forward to it. Best wishes, Charlie

Good video! What he said at 3:00 to 3:13 seems contradictory though. He says only un-polarized light with angles in all directions can pass through, then he says only light waving a certain way gets through. Did he mis-speak with that first statement? Or am I misunderstanding what he said?

That has to be a mistake. Maybe he started with one idea and finished with a different idea.

I think he means light that is being bounced in the opposite direction from what you polarized can come through.

@d.mort. 4 жыл бұрын

I’ve been looking for an explanation for quite some time. Sadly this is not correct but I can’t fully explain the correct answer. According to the equations, and experiments in labs, it is the electromagnetic waves (direction determined by electric portion) that are parallel to the polarizer that are blocked and the perpendicular ones that are allowed to pass through.

It is not required to have two layers of glass to filter polarized light. Sunglasses often have polarized lenses that function on the same concept.

CPL Filters are slightly different than linear polarizers, Ill make a video explaining the differences, the main thing is to first understand how basic polarizers work.

@darthgzuz 7 жыл бұрын

r u saying polarizer filters make light un-polarized Definition of Polarize: restrict the vibrations of (a transverse wave, especially light) wholly or partially to one direction. what i think ... polarizers stop/divert light from entering which are coming from certain directions ... as in real life, light reflects from various surfaces and comes in many direction to the sensor and all this polarizer filter is doing, is allowing some directional light n stopping other light coming from other directions

yes i have seen it ... so like i said, a polarizer stops/blocks light from certain direction ... only reflected light (reflected/polarized light) n not refracted light thats why we can still see/capture objects under water in a lake etc

@nameismetatoo4591 4 жыл бұрын

You missed the chance to really blow our minds! If you place a third polarizing filter in between the horizontal and vertical polarizers, you will actually see some light coming through all three. The first filer is horizontal and blocks 50% of the light. The second is held at a 45° angle to the first, so it lets 50% of the light coming through the first, or 25% of the original light. The final polarizer is vertical, but since the light hitting it is at a 45° angle due to the middle filter, it actually lets through 50% of the light (or 12.5% of the original). Just by placing 1 filter in between the first two, you can actually *increase* the amount of light that comes through!

@XThunderBoltFilms 5 жыл бұрын

I know you are doing your best to explain this without using electromagnetic theory, but your description of how polarizers work is wrong. You were correct that when sunlight reflects from a flat surface it is horizontally polarized (S polarized), however to block this light, the grating should be parallel to the direction of the light in order to cancel it out. This is because the oscillating electric field of light parallel with the wires generates an electric moment, exciting the electrons effectively turning the energy of the wave into heat. Your description is the opposite, because you are trying to describe the wave as a physical piece of matter. Basically, if light is coming in like this , and your grating looks like this |||||, it should have no effect on it. As I noted, your description is the opposite

Please redo this video. The physics is wrong, as you admit in the comments. So why do you keep your name attached to something that is incorrect? You start by talking about circular polarizers, but nothing that comes after that has anything to do with circular polarizers. As you can see, many photographers are grateful for your explanation. But now they have incorrect information locked into their brains. I wish I didn't have to sound harsh, but the truth is: you are promulgating misinformation. There's already too much of that on the Internet. For your fans and their trust in you: redo this video!
