Understanding pixel/point size and resolution

Earlier on in this title, I had us change our type preferences so that we see…our type in pixels, as opposed to points.…And here is the reason why I had us do that.…When we are in pixels, our type size is expressed as an absolute number.…When we are in points, our type size is always going to be relative to the…resolution of our image.…So, if I select this piece of type--I am just going to insert my cursor and…press Command+A to select all of it--…we can see that it is 166 pixels.…
