Glow

Hello Fablers, and welcome back to another Fable Academy tutorial. And this one, we're going to look at the Glow effect. So we have our scene here with a simple JPEG image. Let's select our layer, go to the top right here to the effects panel, and we're going to type in Glow. Click, drag, and drop.

Now immediately, we start to see here that it's a nice little subtle effect, but it can really add punch to your images or to your compositions. Once the glow is applied, subtle effect, it basically works as a glow would in any other, compositing package. It highlights the highlights and kind of blooms it out a little bit and makes it look really beautiful.

So we have a couple of sliders here, intensity, as you would expect to the right, makes our highlights brighter. To the left, turns it down. Zero being no effect at all.

Next we have our radius. You'll notice here that the further the left would go. The tighter the falloff becomes. The further to the right. We go, the more expensive our falloff becomes.

So basically if you want a smoother blending between your highlight sources and your image, you're going to want to push this radius towards the right next. We have our threshold, our threshold determines where the line is drawn for which values will be used to drive the. The left is lower. Meaning almost any brightness will work to the right means.

You would have to have an incredibly bright section of the image in order for this effect to take effect. And lastly, we've got here, our threshold smooth, which determines just how smooth this sort of clamping of the threshold really is.

This checkbox here, clipped to bound. If you notice right now, we've got this nice fall off and it's kind of in getting a little bit on the edges. If you clip it to the bounce, it's going to push our glue all the way to the edge of our bounding box. Great. If you want to have a seamless integration elsewhere, and also if your light source exits your frame.

Lastly, we've got our blend modes. As far as the glow goes, I'm not particularly sure where you would need to use a different one of these. But it's by default set to add, which is what we want. I would say 9 out of 10, if not 10 out of 10 times, you're trying to make something glow. It has to do with the highlights. So blending mode here on the ad is by default and what shall we use most of the time?
