screenshot showing dimensions 2880x1800 but resolution 144x144 I am trying to take some high quality screenshots on my 13" MBP for a website - they need them to be as high resolution as possible (at least 1000px wide) - when I take the screenshot (command+shift+3) and look at the info in Finder it shows dimensions of 2880x1800 but a resolution of 144x144... what is the difference and can I take screenshots at a higher resolution somehow?
Dimension is the actual height and width of the image in pixels.

Resolution (or DPI) is the number of pixels in a square inch.
