•  Iris/Aperture is measured by f-stop, indicated by sequence of f-number: f/1, f/1.4, f/2 , f/ 2.8, f/ 4, f/ 5.6, f/ 8, f/ 11, f/ 16, f/22 , f/32..

SHUTTER:

Lenses - wide angle lens, telephoto lens, standard lens

Wide angle lens:

• ideal for fitting a large area into your frame
• especially useful for landscape photography or street photography

Standard lens :

• offer a fairly accurate representation of what the human eye sees, both in terms of visual angle and perspective.

Tele lenses :

• great for isolating a subject that is far away. 
• allow you to photograph subjects from a distance thanks to their magnification. 

Smartphones vs Cameras = Convenience vs Quality

• quality:DSLR cameras are designed to capture images. Phones are designed to carry out a multitude of functions.
• sizes: phone cameras are very limited by size. the size of the lens and the size of the sensor that captures the photos. Entry-level DSLRs have much larger lenses and sensors than mobile phones do.
