- prime lens: only one focal length
- zoom lenses: variable focal lengths
- AF =(autofocus) MF =(manual focus)
- high iso value means the sensor will be MORE sensitive to light, meaning it will take less light to get the right exposure
- more available light = lower iso
- less available light = higher iso
- shutter speed: how long the shutter is open
- fraction: focal length divided by lens diameter
- smaller number actually represents a larger opening
- larger aperture, shallower depth of field
- most cameras have presets have daylight, cloudy, flash, various
indoor lights - P (Program) – camera sets shutter speed and aperture, but you can choose ISO, AF/MF, white balance
- Tv (Shutter Speed priority) – you choose shutter speed, camera chooses appropriate aperture
- Av (Aperture priority) – you choose aperture, camera chooses appropriate shutter speed
- M (Manual) – you choose EVERYTHING
- A-Dep (Automatic depth of field) – camera chooses aperture, shutter speed combo to get best DOF
- the denominator becomes the f-stop number
- your shutter speed should be double your frame right
- use the lowest ISO you can to avoid grain/noise
- dslr cameras are differnt from phone cameras because they have detachable lenses
