- Mirror system inside lets you preview through the viewfinder the same image that is being captured on film/sensor
- Less than 21 mm is for extreme wide angle and for architecture
- zoom vs. focus
- HIGH ISO value means the sensor will be MORE sensitive to light, meaning it will take LESS LIGHT to get the right exposure
- The shutter in a camera is half a circle (180 degrees)
- camera shake: occurs with a shutter speed slower than 1/ [focal length] of a second
- fast lens has bigger maximum aperture
- longer lenses APPEAR to have a shallower depth of field because they are magnifying the subject, which flattens the perspective and makes our eyes think the DOF is shallower
- Setting the “correct” white balance setting tells the camera how to make your whites and grays neutral, without any color tint
- camera does almost everything BUT lets you choose brightness, depth of field, picture style by pressing the Q button
- M (Manual)– you choose everything
- Tv (Shutter Speed priority) – you choose shutter speed, camera chooses appropriate aperture
- Av (Aperture priority)– you choose aperture, camera chooses appropriate shutter speed
- A-Dep (Automatic depth of field) – camera chooses aperture, shutter speed combo to get best DOF
- P (Program) – camera sets shutter speed and aperture, but you can choose ISO, AF/MF, white balance
- Digital cameras that resemble 35mm film cameras
- one major way that DSLRs are different from consumer “point and shoot” cameras or phones: detachable lenses
- prime lens are only one focal length
- zoom lenses are variable focal lengths
- if you are buying a camera and the price seems really low, make sure the price includes a lens
- 21-35 mm are for Wide Angle and for Landscape
- Lenses must be properly cared for
- Metaphors to understand how exposure is determined by window, garden hose,tanning
- to describe sensitivity of digital sensors in digital cameras
- more available light is lower ISO, less available light is higher ISO
