717 Smoothing out jagged contour lines

- [Instructor] In this movie,…I'll show you how to take rough or jagged contour lines,…and make them absolutely porcelain smooth.…So, let's say I zoom in to this section right here…and I'll go all the way in to 300%,…and you can see that we have…some pretty darn jagged transitions…and we have some very colorful anti-aliasing as well.…Compare that to this much more desirable effect…in which the lines are perfectly smooth…and the anti-aliasing is neutral.…That is to say, at least where the lines are concerned,…we're just seeing shades of gray.…

Alright, so here's how we're gonna pull it off.…I'm gonna zoom out just a little bit here…and I'm gonna turn the H lines red layer off…for the moment, so we can focus our attention…just on the blue lines.…And by that I don't mean that the lines are blue,…although we are seeing some blue anti-aliasing.…The word blue references the channel…upon which this displacement is based.…Alright, with that layer selected,…you wanna go up to the filter menu,…choose blur, and then choose Gaussian blur.…
