Aperture, iso and shutter speed

-
Aperture 
It refers to the opening of a lens's diaphragm through which light passes. It is written as f/stop, which the numbers are 3.5, 5.6, 8,11,16 (based on Nikon FM 10). Basically, with a lower f/stop, a more shallow depth of field occurs. Meanwhile, with a higher f/stop, a deeper depth of field occurs. 



Iso
It refers to a camera's light sensitivity. The iso values are 25, 50, 100, 200, 400, 1000, 1600, 3200 (based on Nikon FM 10).With a higher value , the brighter the photos are. Also, the photos become more grainy. 



Shutter speed
It refers to speed at which the shutter of the camera close. Shutter speed of Nikon FM10 are 1/1 to 1/2000. Faster shutter speed has a shorter exposure, slower shutter speed has a longer exposure. A faster shutter speed is suitable for taking action photography in order to capture a sharper result.

Moreover, there is more light on the middle. It creates a mystery atmosphere. I am impressed by Maynard flawless printing techniques. They look so realistic in this image. I like the way that she used to show surrealism . It i...
