Calculation should include determining
- the number of pixels of the output (multiplying total vertical by horizontal pixels)
- the minimal megapixels required to capture the image without resizing it
- resolution requirements for web output
- resolution requirements for print output
- resolution and its relationship to cropping the image.
Process/Skill Questions:
- What is the formula for determining megapixels?
- Why are cameras commonly rated by the number of megapixels they can produce?
- How do megapixels relate to image quality and image need?
- How much resampling is too much?
- When is there too much resolution?
