Exposure (2)

 The necessary controls of a camera for exposure adjustment. 

1. 1- Shutter speed — How fast the shutter opens. Faster shutter speeds let in less light.
2. 
   
3. 2- Aperture — The amount of light let into the lens. A lower aperture (f-stop) means your lens is wider, which lets in more light.
4. 
   
5. 3- ISO (International Organization of Standardization)— Your camera sensor's sensitivity to light.
