Join Steve Caplin for an in-depth discussion in this video Adding the Detect Edges filter, part of Affinity Photo Essential Training.
- You'll notice that as we've added our three adjustments to this layer, in the form of our three live filters, they're all nested underneath the copy of this background. As well as turning them on and off individually, we can turn this whole copy of the background off. And there is our original image. This is the picture we started with, and I hope you'll agree that this is a significant improvement from what we had before. Let's try adding a special effect to it.
I'm going to take this original background layer and drag it right to the top of the layer stack. This time, I'm going to go to this Traditional Filters menu and I'm going to apply Detect Edges. It picks out the edges between areas of high contrast and outlines them in white, leaving the rest of the image black. This completely swamps the image of course. But suppose we change the mode of this from Normal to Screen.
In Screen mode, the black disappears, and we only see the white. And this now adds a faint drawing effect to the whole image. Let's zoom in. And as we zoom in, you can see how this effect works. Again, I think that's rather too strong. Let's reduce the opacity of this. We can try it at 70%, maybe 40%, maybe even down to about 30%, and there I think is quite a nice compromise.
That's how it was before, and here it is with that Edge finding on just 30%, giving it a little bit of extra crispness. Let's review the whole image. And there is our finished image. We have three live filters applied to it, and one regular filter that's applied to a copy of our background set to a low opacity in Screen mode. If you're going to apply live filters, you can change this as much as you like whenever you like if you're applying a dedicated filter, such as the find edges we did on this one, it's always worth making a new copy of the background and applying it to that to maintain your flexibility.
