Formulas for finding shutter and aperture.

The aperture is calculated by F! The larger the f value, the smaller the aperture!

Aperture is calculated by one-third equation! Each aperture is divided into three levels. If the aperture is now 5.6, then any one of 6.3 and 7. 1 is called one third.

So is the shutter. Each shutter is also divided into three levels. Now the shutter is1125, so every shutter in the middle of1125-1/250 is called one third!

So is ISO!

For example, your current aperture is 5.6, shutter is1125, and ISO is 200! Then open the aperture to 6.3, and the shutter is lowered to1100, and the ISO remains unchanged! The exposure of the photos taken is the same! You changed the aperture to 6.3, the shutter to1125, and the ISO to 250, and the exposure of the photos taken was the same as before! Anyway! Aperture, shutter and ISO complement each other! If the maximum aperture of your lens reaches the lens limit and the shutter reaches the limit of your hand-held camera (generally, the hand-held camera is at least 1/30), and the photos taken are still underexposed, then improve ISO!

In film and television, the lens has two fingers, one refers to the optical elements used by film cameras and projectors to produce images, the other refers to the continuous picture taken from power on to power off, or the fragment between two editing points, also known as the lens.
