- DSLR – “Digital single lens reflex.”
- There’s a mirror in the cameras that allow you to preview through the viewfinder.
- The major way that DSLRs are different is the “point and shoot.” (Detachable lenses.)
- Prime lenses only have one focal length.
- Zoom lenses are variable focal lengths.
- Understand how exposure is determined
- ISO – International Organization for Standards.
- High ISO means more sensitive to light.
- Lower ISO means Less light to get the right exposure.
- The more light you have the lower ISO
- The less light available the higher the ISO.
- But recommended the lowest ISO you can to avoid grain/noise.
- Shutter speed is how long the shutter lens is open.
- The shutter in a camera is half a circle. (180 degrees.)
- your shutter speed should be double your frame rate.
- shutter speed: 1/60 of a second
- Camera shake: occurs when a shutter speed is slower than {focal length} of a second.
- Aperture is also known as the f-stop.
- Fraction: local length divided by lens diameter.
- Smaller number actually represents a larger opening.
- “Fast” lens has the maximum aperture.
- Changing the “correct” white balance setting tells the camera how to make your whites and greys neutral.
- CA – Creative Auto. camera does almost everything for you.
- M (Manual); A-Dep (Automatic depth of field.)
- Av (Aperture priority); Tv (shutter speed priority); P (program)
