Aperture, Shutter Speed and ISO

Aperture

1. Eyes

2. the smaller the aperture the amount of light going through the lens is going to be smaller.
    the bigger the aperture the amount of light going through the lens is going to be larger.

3. Larger the aperture it can focus small amount of area, but with smaller the aperture it can focus larger amount of area.

Slow Shutter Speed

ISO

 

1. It can quickly capture the moment without the blur to the image when there is not enough light.

2. Always use lowest ISO possible when you shoot photos if there is enough light.

3. High ISO is needed when you take ultra-fast shots, like sports event, animal moving.
