LUX vs LUMEN vs NITS What is the difference? Lighting terms | Optometrist Explains

LUX vs LUMEN vs NITS | Optometrist Explains
Sometimes when choosing lights for a shoot the lighting terms can be very confusing
Hello and welcome back everyone!
Whenever I make a purchase decision on lighting equipment I run into so many different ways these manufacturers measure their product.
Lumens, Lux and Nits just to name a few.
While I did my degree in Optometry we had to learn these terms in order to provide the best vision to people in need.
This is just the beginning when it comes to vision science. So stick around for more content!

Thank you for watching and I will see you in the next video!

This is fascinating! You explain this SO well that it feels like a longer video because there’s so much information that you’re able to just make understandable! Thank you so much for making and sharing these videos, I’ve learned more in 15 minutes than I did in high school and collage, and hours of googling combined!

[@philruu]

my bridge now is using the alphabetical order of the terms as this is the order of how filming would also check it: 1.) Lumen - turn on lights 2.) Lux - check how bright the subject looks or if the speaker gets blinded 3.) Nits - check it in the camera

[@DhritiSoni1703.5]

Woah that's easy!!! Thanks!

[@user-zo6iu4ll3o]

This is a super great video, I'm studying for the NCIDQ and have been dreading studying the chapter about light. This helped SOO much, thanks for putting it together!!

[@paternyao]

Buddy, you’re an Emeritus Professor of another level, you’re alone there. I have been watching hours of videos with complicated equations in search for what nits are (I am Msc in Maths & Finance); got nothing as clear as what you have cooled down in only 3min. Kudooooos 👍

[@DhritiSoni1703.5]

So happy to have found your channel!!!!

[@mariawarters4340]

So help full for my interior design diploma 😁

[@JAMESDOWDELL-dv9se]

Great information! BUT I would like to see so more information correlating exposure levels to lux levels, where these are actually controllable around a studio set. You have a wonderful teaching style. Please continue!

[@sunnymahajan863]

props to you Antonio for a job well done! you explain concepts really well -- looking forward to more videos. :)

[@AntonioTheOptom]

Thank you Sunny! I really appreciate the feedback! I promise to bring better content in the future :)

[@oliveramory1378]

Super clear explanation!

Thank you thank you! 🙏

[@FangshiZhu]

Such great explanation!

Dude it was a great video, now I know them clearly, thanks! 😊

[@AntonioTheOptom]

Yay!! 👍👍

[@sarimkhan5309]

Well explained ❤

[@RandoTechInfo]

Hello sir. I am a fellow content creator and I am in the process of producing a video comparing the screen brightness of various mobile devices. I hope you don't mind, but I plan on recommending this video to people who want to learn more about the different types of lighting intensity terminology. I plan to post the video this Friday or early next week. Just wanted you to know. Great explanations by the way.

[@nilsen5109]

Nice video man.you made it really easy to understand.. thanks 🥰

[@AntonioTheOptom]

Thank you for enjoying the video! It made my day 🤗

[@BilalQadirKhan]

woah, that was an awesome explanation.

[@fireum92]

Thanks! Very helpful

[@MILAMIRANDAOFFICIAL]

This is such a great video

[@erikh8685]

Thank you!

[@alef3356]

Thank you!!

[@redacted_lol]

Fantastic video!

[@sabin5162]

Great video! Can you make a video on how we perceive different ranges of nits? In a dark room vs a well lit room maybe?

[@AntonioTheOptom]

Oh that’s a good idea

[@msanand7]

SImple!! Excellent!

[@dhk4992]

Well explained!

[@AntonioTheOptom]

Thank you !!🙏🙏

[@rinky_dinky]

so as far as i am concerned with buying a flashlight , lumens is the measure of how bright the led can put out , but the lux is the measure of how much light the flash light can throw out to a object at a given distance (reflector design, depth, bezel size )?

[@user-nc8jk2qi6p]

thanks dude

[@msaikrishnapattnaik6564]

Top notch video. Love from India ❤️.

[@AntonioTheOptom]

Love from Australia! 😺

[@gunamuthu9284]

Thanks a lot!

[@AntonioTheOptom]

No problemo! 😁

[@nipasy]

Direct. I like it.

[@x9rtu3os1t8]

Nice Bro.

[@genguin1198]

Thanks a lot

[@AntonioTheOptom]

No worries! And thank you for watching!

[@SLPCLK]

superb brother

[@AntonioTheOptom]

Thank you!

[@DivyeshVegad]

luminance is still confusing part

[@alvin_scholarhills2817]

There is one simple question. Is there a way to derive the relationship between 1 lumen and 1 nit?

[@yash1152]

3:10 so, what does the nit value of a display signify? the following part of iphone 800 nits doesnt help at all.

[@randomtube8226]

Has anyone measured the sun? What were the results?

[@aMan-fq7zt]

👏🏼👏🏼

[@sfbluestar]

If "Lux" depends on distance between light source and the reflecting service, doesn't the perception of "Nits" also depend on the distance between the reflecting service (human face in your example) and the receiver (camera in your example)?

[@AntonioTheOptom]

Yeah sure but you only measure nits radiating from the source, not from where the light came from to begin with

[@hershchat]

Not too too clear. Flux (according to you) is total light energy emitted. Is that over its lifetime, or per unit time? How is this (luminous flux) different from luminosity, which IS the light output per unit time of a source? Is nits a subjective metric, or an objective but relative quantity? What is the rate of light production, vs. rate independent measure of brightness?

[@itsokswallow]

wowwwwww!!!!!

[@lindacalinao981]

I need literal meaning of flare pls

[@upschidden4228]

best

[@itsokswallow]

oh hell

[@itsokswallow]

It’s a nice video length 🙂

[@armanis1234]

Nits means marketing bs

[@muzamilzaman7463]

Convert lux into watt
