Photoshop Tutorial: How to Replace a Sky in a Photo


This is Marty from Blue Lightning TV.

If you havea photo that has a burnt-out sky, I'm going to show you how to replace it with a beautiful,blue sky with white clouds.

This is an update of a tutorial I did on an earlier version of Photoshop.

Open a photo that has a sky you'd like to replace.

If you'd like to usethis photo, I provided its link in the video's description or project files.

The first stepis to make a selection of the sky, so we can isolate it from the rest of the photo.

Thereare many ways to make selections, however, for this example, I'll go to Select and ColorRange.

If you're using this method as well, choose "Sampled Colors".

Make sure "LocalizedColor Clusters" is unchecked.

The Fuzziness is approximately 95 to 100 and "Selection"is ticked.

In the thumbnail, click on the sky and then press and hold Shift as you clickon other areas of the sky until it's completely white.

Then, click OK.

Invert the selection by pressing Ctrl or Cmd + Shift + I.

Go to Select and Refine Edge.

I did an in-depthtutorial on Refine Edge, so to save time, I won't be going over all the details here.

Check Smart Radius and increase the Radius approximately 4 to 5 pixels.

Brush over theedges of your landscape to refine them.

Decontaminate the colors approximately 70% and output it as a New Layer with Layer Mask.

Then, click OK.

Click the box next to the Background tomake the layer visible and click the Layer Mask to make it active.

We'll invert the layer mask by pressing Ctrl or Cmd + I.

Click the the thumbnail of the layer to make it active.

Click the foreground color to open the Color Picker.

In the hexadecimal field, type in:88B8FF.

Then, click OK or press Enter or Return.

Your foreground color is now the color we just typed in.

We're going to fill the top layer with the foreground color by pressing Alt or Option + Delete.

Make a copy of it by pressing Ctrl or Cmd + J.

In this layer we're going to make our clouds.

Make your foreground and background colors revert backto its black and white, default colors.

To do this, press "D" on your keyboard or click this icon.

Go to Filter, Render and Clouds.

Change its blend mode to Overlay.

In the next few steps, we're going make the clouds look more like clouds.

The first step is to makethem look a bit less feathery by removing the darkest tones of the cloud layer.

First,click the chain-link to unlock the cloud layer and its layer mask.

Now, we can move and resizeeither of them independently of each other.

Double-click the cloud layer to open its Layer Style window.

In the "Blend If" section, go to the right half of this slider and press and hold Alt or Option to split the slider into two parts.

Drag theright half of the slider approximately half way across.

Doing this removes the darkesttones, making the clouds look less feathery Click OK to close the window.

Next, we'll stretch out the clouds and place them in perspective.

Open your Transform Tool bypressing Ctrl or Cmd + T.

At the top, you'll see the percentages for the Transform's widthand height.

In the Width field, type in 200%.

If the Height also changed to 200%, clickon the chain-link to unlock it and type in 100% for the Height.

Then, press Enter orReturn.

Since the clouds are stretched out 200%, they extend past our visible canvason both sides.

We'll crop them off by pressing Ctrl or Cmd + A to select the document and go to Image and Crop.

To deselect it, press Ctrl or Cmd + D.

Open your Transform Toolagain and zoom out of your document by pressing Ctrl or Cmd plus the minus key on your keyboard a few times.

Go to Edit, Transform and Perspective.

Go to a top corner and drag it out approximatelythis much.

Then, press Enter or Return.

Open the Transform again and go to the bottom, middle, anchor point.

When you see a vertical,double-arrow, drag it up to where your landscapeand sky meet.

Press Enter or Return and fit it back on your canvas.

Next, we'll make our sky bluer at the top.

Click the New Layer icon to make a new layer.

Go to any layer mask and press and hold Alt or Option as you drag a copy of it next to the empty layer.

Make the empty layer active and change its blend mode to Overlay.

Open your Gradient Tool and open your Gradient Picker.

Click the Black to Transparent gradient and click the Linear gradient icon.

Go to the top of your document and press and hold Shift asyou drag the gradient line approximately halfway down your document.

Then, release.

Since skies are generally less blue at its horizon, we'll lighten our sky, as well.

Make the blue layer active.

Open your Dodge Tool and invert your foreground and background colors by pressing "x" on your keyboard.

Open your Brush Picker and type in a relatively large size for yourDodge Tool.

I'll use a size of 200 pixels.

Make the Hardness: 0%.

For the Range, chooseMid-tones and the Exposure is 100%.

Brush and back and forth over the horizon to lighten the blue.

As I toggle back and forth, you can see the difference.
