Digital cameras are the initial device to capture images although
various things can be altered to make sure the images are the best quality they
can be. Image capturing is simply getting images onto a computer. Usually
devices such as cameras or mobile phones are connected to the computer with a
USB and the images are downloaded and saved automatically as JPEGS. Scanning is
also a method used to transfer images onto a computer and is done by simply
scanning the document and a duplicate is created on the screen. Again these are
most commonly saved as JPEGS which is lossy compression meaning quality of the
image may be lost. However other file formats that images can be saved as
include GIFs and PNGs.
You can choose what resolution you would like images to be saved as
the majority of the time, meaning how many pixels per inch the image has.
