Step 1: Image Preparation and Selection

First, choose the image you want to work with. (You can find the image link in the description box if you're following along with a specific example.)

1. Select the person in the image:

   • Use the Select by Color tool to select the background by left-clicking on the area surrounding the subject.
   • In the tool options, make sure to:
     • Set the mode to Add to the current selection.
     • Check Antialiasing and Feather edges.
     • Set the feathering radius to 5 pixels to ensure smooth edges.

2. Grow the selection:

   • Since we're selecting the background, we need to grow the selection to eliminate any white edges around the subject.
   • Go to Select > Grow and increase the selection by 2 pixels. This step ensures a clean cut.

3. Clean up unwanted selections:

   • If the tool accidentally selects parts of the subject, use the Free Select tool to manually subtract from the selection.
   • Set the mode to Subtract from the current selection, and draw around the unwanted areas. Press Enter to finalize the change.

Step 2: Removing the Background

1. Add an alpha channel to make the background transparent:
   • Right-click on the image layer in the Layers panel and select Add Alpha Channel.
2. Cut the background:
   • Press Ctrl+X to remove the background and Ctrl+V to paste it into a new layer.
   • You'll notice that the cutout becomes a floating selection. Click on the new layer icon to place it on a fresh layer.

Step 3: Duplicating and Desaturating the Layer

1. Duplicate the layer containing the subject by clicking on the Duplicate layer icon.

2. Desaturate the image:

   • Select the duplicated layer and go to Colors > Desaturate.
   • Slide the saturation all the way to zero and press OK. This step turns the image black and white, creating a contrast for the warp effect.

Step 4: Applying the Warp Effect

1. Select the Warp Transform tool from the toolbox.

   • Make sure the mode is set to Move pixels.

2. Adjust the tool settings:

   • Set the brush size according to the part of the image you want to warp. You can experiment with smaller sizes for more precision.

3. Apply the warp:

   • Start warping the duplicated layer by clicking and dragging the pixels in the direction you want the dispersion to flow. Use Ctrl+Z to undo any mistakes and make adjustments.

Step 5: Finalizing the Warp Effect

1. After warping, select any other tool (like the Move Tool) to confirm the warp.

2. Create a new layer from visible:

   • Right-click on the layer and select New from Visible. This flattens all visible elements into a new layer, preserving the warp effect.

Step 6: Adding a Background

1. Create a new layer and fill it with a solid or gradient background color. Here's how:

   • Right-click on the Layers panel and select New Layer.
   • Choose a color (like light blue) and use the Bucket Fill Tool to apply it to the new layer.

2. Rearrange the layers:

   • Move the new background layer below the warped subject in the Layers panel.

3. Final adjustments:

   • If you wish, you can further tweak the background or add effects until you're satisfied with the final look.

Step 7: Finalizing and Exporting

Once you're happy with your warp dispersion effect:

1. Right-click and select New from Visible to merge everything into a single layer for final touches.

2. Export your image by going to File > Export As and save it in your desired format.
