Working with interpolation

Here I would like to discuss the difference between and the significance of Optical Resolution versus Interpolated Resolution. I've opened up an image of an O that I've scanned with my scanner at a resolution of 1200 pixels per inch. I chose 1200 pixels per inch for two reasons. One, it gives me enough detail that I can get a really sharp consistent edge as we'll see, but I also know that this is the optical also known as hardware resolution of the scanner. What that means is that the scanner is actually set up to actually physically capture pixels at one- 1200th of an inch on the side.

So this is going to capture 1200 pixels in every inch horizontally and 1200 pixels in every inch vertically. The reason why this is important will become clear in just a moment. So this is a 1200 pixel print scan and I'm going to zoom in on this so we can take a look at these two edges right here and you'll notice there is a real consistency to the placement of pixels. There is a little mi...
