Lens Flares [1]. What causes them and why. 

Nice video. But the starburst explanation at 4:50 is wrong. Each blade produces diametrical streak perpendicular to it, due to diffraction. So 5-blade aperture would produce 10 radial streaks. So the left picture is wrong and cannot be observed in real world. Have you ever seen a starburst with odd number of streaks? Analogically, the right picture is wrong. The middle picture has even number of blades, so it will produce 6 radial streaks indeed, but the rotation in your example is wrong. The picture or the aperture scheme must be rotated 30 degrees to be correct.

Nicely done. We get a lot of "UFO" photographs that are in fact, lens flares, and this video explains it better than we can.

Uhhh you're so good a explaining things. Good job!

Thank you, these videos have been incredibly helpful. Your animated illustrations and charisma really helped with retaining my attention lol.

wow, I just found a treasure! Thank you for this nice video, really easy to follow.

Thank you so much!!! For this video two days ago I did a night long shutter speed car photography and the problem with it was starburst and after editing single picture for 2 days (with alot of reconsideration to solve the problem) but wasn't able to dismantle the Starburst but now I understood that it. Was because my aperture was F16 and it should've been F1.8-2.8

Thank you so much for this! This helped me understand what sort of lens flare to photoshop into my pictures.

Dude seriously good explanation, i always wondered, and even if there are some generalizations (explained in another comment as a mistake) I got the theory! Thank you so much.

Fantastic explanation! Really clear as always. Keep up the good job!

thanks for this ... helped the day and night cycle in game

All 'NIBIRUTARDS should watch this video. They might actually learn something. Good job explaining lens flares.

So many superb quality videos lately! How do you manage it? I hope to see your channel grow.

Great video!! Very well explained, thank you!

Excellent explanation, thanks!

Very informative video, Thank you!

This helped me understand beautifully!! Thank you for making this video 🥺🙏

very well made

Yeey another video :)

Super useful. Can I ask what causes the Chroma Rings and Chroma Bands you mentioned briefly? I have seen them also in spherical lenses. What they depend on?

Very informative video and useful. ND filters are a must.

The aperture starburst thing is wrong, the five blade aperture would have shown a 10 stars

Awesome video man! Thanks a lot

I get it now. I really do! Awesome! Thx for this video!

Thanks for beautifully explained👌🌹😷

Every nibiru freak out there should see this :D it would turn their world upside down, since these people dont have a clue about how this stuff works, great job, wish you a lot of growth on this channel ^_^

Super thank you for sharing it

4:06 what music is being played in the background?

Amazing quality, you earned another sub. Do you mind if I ask what the font used at 1:50 is?

Once again, great vid! Keep it up :D

Great video!

Are lens flares almost like a type of light Doppler effect? How the light changes color and shape?

Song name bro

I still don't understand the flare in my video. It moves at its own speed, like a butterfly even if I keep my hand steady to make the video.

This is not true. It is energy

Makes you wonder about all those suspiciously round blobs of light in the sky, right? What's the current doctrine? Massive balls of "rock" floating around up there. Are we absolutely sure about that?
