aperture: F 2.8, 4, 5.6, 8, 11, 16, 22

shutter: 1000, 500, 250, 125, 60, 30, 15

Study their reciprocal relationships (e.g. what is an equivalent exposure to f4 @ 1/60 if the aperture is changed to f5.6?)

What is changed when you move from one setting to the next?

How do you take an extra long exposure?

What is the exposure triangle? What 3 factors determine exposure and how are they related?

What happens when you change your iso/asa?

What is depth of field?

What is focal length and how does it affect depth of field?

What is spot metering?

What are the common digital photography file formats? Tiff, jpeg, raw, ps and how are they different?

How do you preset a digital file for printing (file format, size, dpi)?

Know your lr workflow (importing, collections, processing, output).

What is a histogram, levels, channels, saturation, lightness, hue?

What is a pdf?

Which Zone does your camera's meter calibrate?
