the difference between optical zoom and digital zoom
is: digital zoom -just enlarges part of of the image which can become blurred.
Optical zoom- moves the lens closer so light from the subject is brought to a focus on the sensor. optical zoom is better because it gives a clear image and does not show a blurred image.
resolution is images made up of pixels.A pixel is a tiny point in an image.A megapixel is one million pixels.the more pixels in an image the larger the file size. resolution is measured in pixels.
metadata is used in cameras by having a GPS receiver so that the geographical coordinates can be stored in the metadata.
GPS tagging stores the exact location of where a video was recorded.
cameras use WiFi for users to email their images or upload them to online albums and social networking sites without the need to download images to a computer first.
