Apature is describing the diameter of a circle, but the amount of light is based on area of the circle. Therefore, amount of light is sqrt(2)*A, or roughly 1.4*A.
@@ConstantineSPhotography So , I came across a question with 4 possible answers and i cannot understand it....here it is: If you want to reduce the sunlight coming in a window by three stops as well as the color temperature from 5500K toa a tungsten balance, which gel would you apply? 1- CTB.9 ND 2- CTO.6 ND 3- half CTO.3 ND or 4-CTO .9 ND .....and I cannot figure it out.....can you help me?
This looks like a complicated question, sorry I can't give you an answer as I'm not familiar with CTO or CTB. I guess this will require some trial and error.
Vous êtes incroyable dans vos explication je comprend tout avec vous 😧, j'aurai aimer vous avoir comme professeur à l'École 😁. Un grand merci de prendre de votre temps pour aider les autres 🙏

I used the ND according to my criteria, not the technician. Now I will try using the mathematical formula . Thank you for teaching us
You're welcome. I normally use ND according to my criteria too, with a variable filter, it really saves lots of calculation time.
this is just what i needed!
@@kalm_kat glad to hear that! Hope everything is clear 😊
Thanks for this well explained and detailed videos. Wishing all the best 🙏🏻💐😊
@@amraouigroup thank you very much, really appreciate your feedback. Greetings from Taiwan 🇹🇼
Best explanation. You earned a follower!! Thank you!
I'm glad you find it helpful. Thanks for subscribing!
Finally an Asian girl gives me a math class on ND filter numbers 😻
Hope you find it helpful 😊
@@ConstantineSPhotography Haha yes it did finally made sense
@@SuperAwesomeReviews-lw6ry glad to hear that!
Thanks for the beautiful explanation.
I'm glad it helped! Thanks for supporting!
Good explanation. Thanks!
I'm so glad to hear that! Thanks for watching!
Thank you for the video, it was very helpful !
I'm very glad to hear that!
Thank you this video was very clear and informative
I'm glad you like it! Really appreciate it!
For 3 stops I can use .9 ND ....CTO or CTB? Thanks
3 stops means 0.9 or ND 8. This is different from CTO or CTB, which are for adjusting temperature.

best explantion ever
Thank you very much! Really appreciate it.
this helps thankss
Glad to hear 😆thanks for supporting
your video is interesting. you are certainly wonderful
@@kentlimleong75 thanks for your kind comment, really appreciate it
The most confusing video ever on ND filter. You just messed me up.
@@EUguitarRULE 😅😅😅
no
中国力量！数学就是好哈哈哈哈哈哈哈哈
🤣🤣🤣
Pls stop using nd filter yhis math will ruin ur shooting
I actually find it helpful sometimes.
