wide angle lens
what enables you to zoom in on an object
telephoto lens
how do you calculate total zoom
optical zoom x digital zoom
what crops the image and enlarges a portion of it
digital zoom
digital zoom results in a zoomed image of lower quality because
the dpi doesn’t change
what uses a zoom lens to change the focal length of the camera
optical zoom
what has a stationary lens with a preset focal length that focuses well on objects within a specific distance
fixed focus
when you point he camera at a subject and the camera adjusts the focal length by using a small motor to move the lens in our out is called
auto focusing
what do you use to focus the camera
focal length
the focal length is the distance at which subjects in front of the lens are in
sharp focus by changing or moving the lens
what is the measure of the number of pixels in an image that is expressed in mega pixels
resolution
how do you calculate resolution
length x width of the image in pixels
you can also measure resolution in
dpi
dots per inch
higher resolution equals
more detain and larger prints that you can make before quality suffers
higher resolution also equals
larger file size
