- [Instructor] One of the strangest ways to distort an image in Affinity Photo is to use the equations filter. Here's how it works. Go to filters, distort, and equations. And this dialogue comes up. You can distort either via Cartesian coordinates, X and Y, or polar coordinates, and we'll look at that a bit later. Let's say we want to make the image half the size. We can do X. The X dimension equals X times two and then it makes it half the width. We can also use the parameters instead of putting in an absolute number. So, we could do X times A. Now, as we grab the slider, it stretches the image out. And that's because one is the absolute end value and as we drag it, we're reducing that value. So, we're multiplying it by a smaller amount. We could also set Y to be Y times A and now if we drag it, it changes both the X and the Y dimensions. If we change this to X divided by A, and Y divided by A, as we drag it, it now makes it smaller. We don't have to have these both the same. So, if…
