This is why you're the best! Thanks for explaining this in a way that makes sense!

Oh, thank you! I think it's enormously helpful to understand why no matter what the issue is, and I have never seen or read an explanation of aperture numbers before! But if you don't understand why, you have to go with "because I said so, " and you KNOW you hated that as a kid, didn't you?!? We ALL did! So: thanks a ton!

Learnt something new after a decade of headscratching (even with a Nikon) - thanks Paul, that fraction explanation was Genius!

Always great to learn the basics Paul refreshers are good to go back to 👍

Oh. My Gosh!!! I've never known that the F was the focal length!! I must not be dying today as I learned something!!! I do appreciate the D3500 have the little graphic on the back. I remember growing up having a special mirror that had a small opening in the middle that allowed one to focus more precisely on something small (I think the theory was it would be a search plane). The see-thru cross would let you see the distant plane more clearly. That always helped me think through what the smaller opening would do for me. Thanks for another great video and explanation Paul!

Thank you for such a clear explanation of a topic that has had me "f-ing" confused for ages. The image of f/2 is now fixed in my head.

All I needed was for someone to tell me the number is a divider. It's all crystal clear now! I wonder no other video I have seen on the aperture takes the few seconds to explain this... Amazing video Paul!

[Twobarpsi]

Great explanation. The ratio of its focal length to the diameter of the aperture.

[rosemarylang]

This is the best explanation I have seen regarding F stop. Thank you

[JV-qbib]

Thanks a million, Paul. You’re the best.

[MrRensan]

Simple and clear explanation. Even after years of using my DSLR, I did not know why they called it F for aperture.

[llynlightpaintingandothers]

Well explained Paul, as usual. Thank you very much for sharing your knowledge.

[block]

The best explanation I’ve ever saw. Cheers from Brazil!

[clairehachey]

Absolutely brilliant video Paul! Nothing else to add. Cheers from Canada!

[jeffreyrhine]

Thanks Paul, I knew that tne smaller numbers were wider but didn't know how they came up with those numbers.

[MrTmiket]
