Understanding Stops: The Key to the Exposure Triangle
Ғылым және технология
What are stops of exposure, and how do they relate to the exposure triangle?
It's essential to understand not just for using manual exposure mode but all of the other exposure modes too. How will the camera adjust those automatic variables when you change something? Don't be surprised!
This simple explanation makes adjusting your exposure really easy, and we'll see what stops are in terms of ISO, shutter speed, and aperture, and how to use them to balance exposure.

Gift from the KZread algorithm! When I finished the video, I was shocked it only had 200 views. Great information.

We’re a small channel :) That algorithm is a bit scary at times but I’m glad it worked for you!
The f/stop concept also applies to full-power, 1/2 power, 1/4 power, 1/8 power electronic flash lighting.
Tank you
This is great, I thought I understood this, but having watched this I realise I didn’t - I do now!

That's awesome, glad it helped!
Thanks, I actually learned something new. I knew the concept of the triangle but never understood how the change in aperture, iso and shutter speed is converted into stops. Does this actually apply the same way to apsc lenses in terms of aperture? I read recently that the F value of apsc lenses is not equal to f value of full frame lenses. So wondering if the convertion rate is there the same(I think the iso value are also different there). But not 100% sure if that’s actually true

Yes, f-stop is f-stop. The formula for the f-stop numbers is focal length divided by the diameter of the opening...there's no conversions between sensor sizes; that's irrelevant. There are, however, some other things that change between the two sensor sizes like apparent depth of field for a given aperture. But that's a whole other can of worms!
