Very nicely done these videos, I love the graphics and the simplicity, very nice.

Hey i have a canon m6 and trying to get the sigma 16 mm f1. 4 af lens, what your thought? Besides astro also want to use it for work

The greatest explanation...!!!

If you wrote aperture sizes in the conventional way…. f/2.8, f/4, /5.6 and so on …. It would be easier to explain or remember that smaller numbers represent larger apertures. Written f/… because the values are FRACTIONS, …. Fractions of focal length. So aperture is a series like shutter speed. Everyone understands that 1/30 is slower… let’s in more light…. than 1/125

this channel is treasure

It's not F8. Its f/8 where "/" means "divided by". The "8" is the fraction of the diameter of the aperture compared to the focal length. Thus for a 50mm nens the diameter of the aperture is 50/8 mm = 6.25 mm. This makes the area of the aperture 1/64 th of the full aperture which reduces the amount of light getting through to 1/64 th. Each stop reduces the amount of light by half, eg. 1, 1.4, 2 2.8, 4, 5.6, 8, 11, 16, etc.

Fuck yeah

how about samyang 14mm f 2.8 AF canon ?

What is the actual meaning of F ? Focal length or something else ?

What about Canon EF 24 mm L F1.2?

this is fantastic! very clear. thank you

سبحان الله وبحمده سبحان الله العظيم

Nicely explained. Genuine content never gets old. 10/10🙌

Music so obnoxious

excellent video thank you

too hard to understand :) not for beginners

This was so well explained and to the point, thanks so much!

As much beauty as there is dangerous 😂..thats solar heat waves effect on electromagnetic plate of earth

Help i only see black :(

Thank you for teaching in easy way

is that house actually on fire in 0:29

Grandios 💪👋👋👋👋😳🤗🤗

Such a good explanation

The northern lights ate emeralds "gods throne" as mentioned in the Bible. Look it up. God's mountain was Mt. ZION aka north pole aka directly under the heavens

Full of mistakes. A common belief is that the sensors "sensitivity " changes according to ISO. This is NOT the case. The signal is amplified after the sensor circuitry.

Aperture and F-stop are inversely related

I watched about 20 videos on aperture back to back and this one helped the most. Thank you.

This is the best video I’ve ever seen. I don’t know how many times I watched it, I don’t know how many times I cried. Thank you. Thank you❤

Slight error. That 35 mm is not a diagonal measurement, it is the total width of the film, including the edges that have holes for manipulating the film's position. 35 mm camera film is exposed over an area that is 36 mm x 24 mm. There are also a number of APS-C lenses that will go down to 11 or 12mm without fish-eye distortion.

How does the battery last all night long?

Beautifully done

👍🏾

01:07 If you express F=stops as a fraction, then you can keep the correspondence between aperture, light, and F-stop: - bigger aperture = more light hitting the sensor = larger F=stop - smaller aperture = less light hitting the sensor = smaller F=stop F1.4 => F1/1.4 F2 => F1/2 F8 => F1/8 F16 => F1/11 Thus F1/1.4 > F1/1.2 > F1/8 > F1/11. Doing it this way makes it less confusing because you don't have be inverting it, e.g., smaller stop means bigger aperture.

Awesome !!!

I love the simplicity of explaining iso and aperature. thank you!

awesome video thank you!

can i drive to this place from the middle east ?

low dynamic range means low contrast?

The Holy Fire that does not consume 🙏🏾💞

Comforting and exciting at the same time 😮❤😊

Currently Canon RF lenses ? Do you have any recommendations, getting into the RF market and looking to give astro a try :). Thanks 14-35 F4 and 24-70 2.8 current lenses but looking at a prime.

What a great way to explain these concepts! Love this tutorial 👏

Oh look the Death Star

hi! Do you have any plans to make an updated version of this video? I am looking to buy a 35mm for astro (Nikon Z8 camera) and am trying to decide between the Nikon 35mm f1.8 S (mirrorless) lens and the Tamron 35mm f1.4 on the FTZ adapter. Any thoughts would be greatly appreciated!

This is first time I heard this northern light really spectacular and Allah is everywhere

Want to see this in real for sure ❤

Thank you so much for making this video!

Que impresionante..que belleza!

Amazing! Just saw some northern lights down here in Alabama. We had an extremely rare and once in a lifetime viewing. Absolutely nothing compared to this. Our view was very faint to the naked eye, but cell phones could capture light you couldn't see. The phones made some amazing pictures..... I have a question. Does it really look like this to the naked eye?? Or is the camera making it look more bright?? You can see the whole ground light up in the video!

wonderful video
