Understanding ISO

on

Key Objectives: 

  • Keeping the same frame, change only the ISO. 
  • Fix the shutter speed and aperture. 
  • Find the perfect exposure at ISO 800. 

My Learnings:

Low ISO lets in very little light whereas higher ISO lets in extreme light (perfect for night shoots, ideally)

Shutter Speed: 1.6            Aperture: 3.5                ISO: 800
perfect exposure picture.

Shutter Speed: 1.6            Aperture: 3.5                ISO: 100
under exposed

Shutter Speed: 1.6            Aperture: 3.5                ISO: 200

Shutter Speed: 1.6            Aperture: 3.5                ISO: 400

Shutter Speed: 1.6            Aperture: 3.5                ISO: 1600

Shutter Speed: 1.6            Aperture: 3.5                ISO: 3200

Shutter Speed: 1.6            Aperture: 3.5                ISO: 6400
over exposed. 
Looks like the image was shot in the daytime, even though it was shot around 10 p.m.
