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

I wanna know how you edited it? How close to the raw footage is this?

Mejor q el vals de las hadas...eS ahora.. Ahhhhhhhh...... maravilla

Is there any copyright for this video?

Thank you for sharing this amazing event.

OH so this is the reason why my landscape shots are not sharp despite having perfect focus in the center. Shouldn't have used f4.

Thank u so much... Greetings from India...

the image on 2:50 really helped me understand the three things more!

Great content! I got a question though.. you said you used canon ef lens mounted on the sony a7r2...so that means, were you able to change the aperture electronically or not? Also what converter do you own?

Good

Disappointed thT Pentax is not mentioned! Yes, it’s far down the list, but some of the lenses are good. The cameras, K1 and K3, do not too bad.

Alomejor resulta que las Auroras no son tan naturales de la Tierra como se dice y hay quienes las crean.Hay muchos por esos lugares

Plz translet Hindi

What do you know about Rokinon 24mm T1.5 (Cine Lens)?

¿Como puedo tomar una foto tal cual mira el ojo humano una imagen?

Thank you so much😊❤

How about the Zeiss Distagon 35 mm F/1.4 or Zeiss Loxia 35 mm F/2? Are they suitable for good astrophotography?

Larger numbers make sense if you think of the number as the denominator in a fraction

bad video

He could've made it a lot easier to understand if he'd explained what an f number actually is. It's the denominator of a fraction. Divide the focal length (f) of a lens by the aperture size; that's it! If the focal length is 50mm, a 25mm aperture gives you f divided by two, or half of f, or f over two, f/2. If you look at the f-stops on a lens, they go 2,4,8,16. The numbers in between are multiples of 1.4, which is the square root of 2 to one decimal point. They go 1.4, 2.8, 5.6, 11. Why the square root of 2? The aperture is circular, so think about that for a second.

Thank you
