Digital photo resolution is based on 72 dots per inch (dpi). The first
photo above is 800 x 600 pixels in size (0.5Mp) and would therefore be
just over 11 inches wide if printed without any adjustment. The second
is picture of the same scene is 2048 x 1536 pixels (3Mp), nearly 2.5 times
the size.
Although both photos are of the same scene, the second has considerably
more pixels, in fact over 6.5 times more and hence offers much higher
resolution, allowing you to see more detail in the picture.
If we scale the lead figure in both photo and compare with a video still it
is easy to see that more pixels gives more resolution and better
recognition.
