Masking clouds in Photoshop involves isolating the clouds from the background and creating a mask that allows you to selectively edit or replace them. Here's a general approach based on available information, focusing on creating a layer mask to reveal or conceal the clouds.
The provided reference, based on a YouTube video, explains setting the output to a new layer mask, which then masks the background.
Here's a generalized process, which might involve using selection tools, channels, or color range selections:
-
Open your image in Photoshop.
-
Select the Clouds: Use selection tools (like the Quick Selection Tool, Magic Wand Tool, or Pen Tool) to select the clouds you want to mask. Alternatively, you can use Select > Color Range to select the clouds based on their color.
-
Create a Layer Mask:
- With your cloud selection active, go to the Layers panel.
- Select the layer you want to apply the mask to
- Click the "Add Layer Mask" button at the bottom of the Layers panel (it looks like a rectangle with a circle in it). This creates a mask based on your selection. White areas on the mask are visible, black areas are hidden. According to the reference, you can set the output to a new layer mask.
-
Refine the Mask: The initial mask might not be perfect, so refine it.
- Using a Brush: Select the layer mask thumbnail in the Layers panel. Use a black brush to hide areas and a white brush to reveal areas.
- Adjusting Mask Properties: Open the Properties panel (Window > Properties) to adjust the mask's density, feather, and other settings. Feathering softens the edges of the mask for a smoother transition.
-
Replace or Edit the Clouds: Now that you have a cloud mask, you can:
- Adjust the Cloud Layer: Apply adjustments (brightness, contrast, color) specifically to the clouds using adjustment layers clipped to the cloud layer.
- Replace the Clouds: Place a different cloud image below the masked cloud layer. The mask will only show the new clouds where the original clouds were.
-
Final Touches: Smooth any rough edges or halos around the masked clouds for a seamless integration with the rest of the image.
Example:
Let's say you have a landscape photo with dull clouds and you want to replace them with more dramatic ones. You would:
- Select the dull clouds using a combination of selection tools.
- Create a layer mask based on the selection.
- Place a new image of dramatic clouds below the masked landscape layer.
- Adjust the color and brightness of the new clouds to match the overall scene.
- Refine the mask edges if necessary.
