Sky replacement, better edges

I have created a few tutorials on Sky replacement in Photoshop already. I’ll add a list at the bottom of this tutorial.

One thing you may have noticed, the edges sometimes have a hazy glow around them. These is a tool, that very few people know exist, let alone use and that’s the sky brush. This short video tutorial and written step by step Photoshop tutorial shows you how to replace a shy and fix the edges.

To change the sky choose Edit>Sky Replacement

Choose a different sky to change the sky (full tutorial on sky replacement here)

The haze looks good on the horizon, but it doesn’t look good up against the sides of the house.

If you look at the Sky Replacement panel, you will see the sky Brush on the top left

Run it around the edges where you want to remove the haze.

You can see how it affects the edge here. Press the [ or ] keys to resize the brush.

What about areas such as the post? We need to do the opposite.

Rather than paint in sky, we want to remove the sky overlay from these areas.

To remove sky, hold down the alt/option key and paint in the image.

The brush has color detection, so keep the central cross hairs in the areas you want to effect.

Here we have painted around the image and cleaned it up.

Photoshop uses a mask and remembers the mask you edited.

Choose other skies and notice you mask is remembered and you don’t have to use the brush each time you change the sky

When you apply the sky, you will see a layer stack. This is the mask we have been brushing on.

After a little color adjustment, here is our final sky swap.

    Very cool! I did NOT know about this, so thanks for sharing, Colin! Seems a bit like the refine edge brush in the select and mask workspace.

  2. Kathleen Towns

    Well you are not alone! I am so excited to find this brush – thank you.

  3. Wendy Drew

    I did not know this and have not used a sky I wanted because of the bleed like the rock post in your tutorial. Now I know an easy way to fix it. Thank you, Colin, for your very helpful and informative tutorials!

    I can’t access the “Freebies” in the Photoshop vault. I do not receive the “confirm email address” email.

    This is one of the reasons I watch every video you release. No I also did not see or use the brush feature in PS sky replacement. I have been using PS for over 20 years and I still need help in finding and using many of the features.
    Thank you.
    Jack

  6. I didn’t know about the sky brush. No surprise since I’ve never replaced a sky! Thanks for the tip.

  7. David Kessel

    In earlier days, I used the dye transfer process to create color prints (via photography). It would have taken an entire day to do what Photoshop can do in a few minutes. Sky replacement was a major challenge and I seldom saw it done well. Now, it’s almost trivial.

  8. Chris Flowers

    I don’t know how I overlooked the sky brush. Now you have prompted me I will be experimenting with it at every opportunity

  9. Tim O'Brien

    Did not know about the brush, so thank you for revealing such a useful and time saving tool.

  10. Had no cooking clue. Thank you for the heads up. By the way I love it when you provide the notes. Thank you so much.

  11. Luna parker

    For the last 3 months I have followed all tutorials and now I am becoming a pro Photoshop Editor.
    Again Thanks Colin Smith

  12. Richard Wade

    WOW! no I did not and I use the sky replacement a lot, I will now start playing around with it. Thank you.

  13. DON EAGLE

    Thanks Colin!!! I had no idea about this brush, but, now that I do….I will certainly use it.

  14. Richard Bourdeau

    Like you I never checked it out. Now I have to go back and review all of my sky replacements:)
    Thanks again

  15. pkinstler

    Sky Replacement brush and Split Warp were very helpful. Thank you!

  16. Frank Burhen

    Double WoW, Colin. Thanks for continuing your short, content filled tutorials. The brush has been hiding in plain sight for me.

    1. Colin Smith Author

      Hi, thanks for letting me know. You can change the font in your browser and system, it will look a little different on everyones system.
      Hopefully you were still able to follow the video version ok?

  17. Rosemarie Culver

    I have used this brush but was unaware of all its features. Thanks. Also I like the short tutorials of one skill.

  18. The brush literally does not work for me! What am I missing?? I open Sky replacement and replace the sky, but I don’t totally like the edge (sky is showing through a hat and one side of a face that has bright highlight levels, but despite pressing alt while using the brush over this area, there is NO change whatsoever. Super annoying, because other than that, I got the sky just the way I wanted it.
