Removing halos with Darken

Video: Removing halos with Darken

So sometimes you are going to end up with a halo in an image, especially if you are shooting JPEG or you have silhouettes against a sky or if you've done some sharpening in the camera. Let's zoom in here and take a look at what I'm talking about. If you look at this edge of this cliff against the sky, you can see where there is this harsh transition it's creating an edge. The orange of the cliffs against the blue of the sky. And it creates this little light fringe or light halo around those edges. So what we are going to do is we are going to quickly paint out that halo using our friend the Darken blend mode. So let's begin by creating a new layer.

Removing halos with Darken

So sometimes you are going to end up with a halo in an image, especially if you are shooting JPEG or you have silhouettes against a sky or if you've done some sharpening in the camera. Let's zoom in here and take a look at what I'm talking about. If you look at this edge of this cliff against the sky, you can see where there is this harsh transition it's creating an edge. The orange of the cliffs against the blue of the sky. And it creates this little light fringe or light halo around those edges. So what we are going to do is we are going to quickly paint out that halo using our friend the Darken blend mode. So let's begin by creating a new layer.

By the way if you hold down the Option key or the Alt key when you click on the Create New button, you'd get a chance to name the layer as you create it. So I'm going to call it Remove Halo and you can also change its blend mode while you create the layer. So we are going to go ahead and choose the Darken blend mode as we create this. I'm going to go ahead and click OK. Currently, it has no effect on this particular document because there are no pixels in the Remove Halo layer yet. So let's go ahead and do this. I am going to get my Brush tool, press B for the Brush tool and what we are going to do is we are going to sample a color that is darker than the halo color. And with the Brush tool chosen, I can switch to my eyedropper temporarily by holding down the Option key or the Alt key on Windows and I'm just going to click on the sky color, next to the halo that is darker than the actual halo color itself.

Now with my blend mode for the layer set to Darken, as I paint over the halo I'm using the blue color that I have sampled and you will see that any pixel that is lighter than my current foreground color is getting darkened as I paint. So I'm just painting and dragging along that edge there, using a very small brush. So very, very quick easy technique for getting rid of halos around edges and you're really just using the image to correct itself to sampling the darker color, darker than the halo. Now if you are using an image that has a dark halo or dark fringe, you just use the opposite of this technique. You would set the blend mode of the layer to Lighten instead of Darken and then you would sample a color that is lighter than the fringe. And as you paint, it would lighten the dark halo instead of darkening it.

So let's turn the layer on and off, here is before, there is after. Very easy quick way to remove halos using the Darken blend mode.
