In the AliveColors editor, open a photo that will be used as the background.
Open a portrait photo. In the Layers panel, right-click the layer to open the context menu and select the Duplicate... command. In the Layer Name field, enter "Portrait". In the Duplicate to field, select the name of the document with the background image and click OK.
"Duplicate Layer" Dialog Box
Go to the document with a background image.
On the toolbar, select the New Shape tool 
. In the Tool Options panel, select Rectangle in the drop-down list and draw a polaroid frame. Change the mode to Subtract from Shape Area and draw a square inside the created rectangle.
Click the icon of the shape layer 
and change the fill color to white.
Polaroid Frame
Rasterize the shape layer. If desired, add a paper texture to the frame using the Texture Brush 
.
Create several copies of the frame and place them in the portrait using the Move 
tool and the Free Transform... command.
Frame Сomposition
Select the first layer with the frame. On the toolbar, activate the Magic Wand tool 
, make sure that the Contiguous check-box is on and select the inner square of the frame.
Activate the portrait layer, copy the selected area (Ctrl+C), and paste the copied fragment as a new layer (Ctrl+V).
Select the layer with the portrait fragment and the layer with its corresponding frame holding the Ctrl key and merge them into one layer (Ctrl+E).
Process other frames the same way.
Processed Frames
Turn off the visibility of the portrait layer.
If necessary, reorder layers by dragging them in the Layers panel or using the commands in the Layers -> Arrange menu.
Select the top layer with the shot and apply the Outer Shadow layer effect using the following parameters:
Outer Shadow Layer Effect
Hold down the Shift+Alt keys and drag the added effect onto the layer with another shot - it will be copied with the same settings. Add a shadow to all shots.
As a result, we get a composite portrait out of a single photo.
