CPP: ISO & Sunny 16 Rule

Steve Kozak M.Photog.Cr., CPP

As a professional photographer, we’re sure you know that the Sunny 16 Rule isn’t about taking Sweet 16 pictures on a sunny day. But do you know enough about it to ace the CPP exam? In this video, PPA Instructor Steve Kozak goes over the rule and other topics such as:

  • ISO Numbers
  • ISO Numbers and their relationships to f-stops and shutter speeds
  • Lighting Patterns and Starting Exposures

Take it from someone who has prepped others for the exam: you need to review these basic! Steve gets straight to the point, giving you exactly what you need to know about these concepts.

We value your feedback and want to know how we can improve. Please share your thoughts about the class here.
