Other Recommended Reading

 
We recommend that you have some knowledge of the basic concepts of photography and optics (focal length, aperture, exposure, etc.) before reviewing the Imatest Training.
 

Cambridge in Colour’s: Learn Photography Basics course is an excellent concise introduction to the key background material.

 

If you have the time, we recommend Marc Levoy’s Digital Photography course, available on YouTube.

 

To focus your learning from Marc Levoy’s course, we have outlined the most relevant lectures to what you will learn in the Imatest training course:

 

We also recommend that you review our Image Quality Factors series for a background in the key factors that determine image quality.
