This tutorial shows you the fastest, easiest way to fix edges on masks in Lightroom or Camera RAW, it’s easy and it really works!

Here is a simple way to get rid of edge halos on mask edges in Lightroom or Camera RAW. We are in the develop module of Lightroom Classic, but this tutorial will work exactly the same for Adobe Camera Raw.

Let’s lighten the foreground and gazebo without changing the sky and water.

Click the new mask button

Choose the ai Subject

A mask will automatically be added to the subject. Sometimes, it will get the whole thing and other times, it will get a partial selection as shown.

We need to add the grassy foreground

In the Masks panel, click Add

Choose Objects

You will see a brush and a selection option in the mask panel. Choose brush.

Paint over the area you want to select. It doesn’t have to be perfect, just enough to let Lightroom/ACR know what you want it to select.

The ai will do its thing and make the selection.

Adjust the Exposure and Shadows to brighten the foreground

Notice we have a light fringe on the transition between the ocean and the foliage. This is called a halo, and it’s common.

Lets fix it

Inside the mask, choose subtract

Choose Brush

Set the feather and flow to 100.

Turn on Auto Mask

If you look at the cursor, you will see a minus sign. This means the brush will remove.

The way auto mask works is to keep the center inside the areas you want to select. We will take the area between the 2 rings and use that to retouch our image. Watch the video at top to see it in action.

Begin to paint

Notice just the area between the 2 rings is going over our foliage, and it’s working nicely!

Here is the result. Some things can be really simple, but still effective.

I hope you enjoyed this tutorial and found it useful!

Thanks

  1. A wonderful tip, Colin! Thanks for sharing. I so appreciate your generosity.

    I wondered why you didn’t use select sky for the mask and then invert it. That always seems to work well.

  2. great, but why did you pick up the golden color and use Auto Mask? You went quickly and I did not understand that.

  3. Colin, great technique. I’ve often run into this issue. Question for you: As I understand it, automask samples from the center of the brush. When you were brushing where the center crossed the dark rock out in the sea, I didn’t see you making any effort to avoid it even though that rock was more like the dark vegetation in the foreground. Can you expand on what level of attention is required on the location of the sample point?

  4. Your explanation was simple and effective. Thank you. Always learn something new with your ‘short hints’.
