You
will need the layers screen open as you carry out this process.
1. Open your image and edit to a size you want to use, remember you will be
increasing the overall size of this image.
2. Do a Ctrl A (PC) or select all, then press Shift Ctrl J to copy the image to
its own layer.
3. Go to Image, Canvas Size and add 200
to the width and 200
4. Us the magic wand or however you usually select areas and select just the
part of the image you want to extend out the picture. It can sometimes be easier
to select the background and invert the selection.
5. Press Ctrl+J to put that selection on its own layer. Now click back on the
original photo (layer 1). Switch to the rectangular selection tool and drag out
a rectangle selection that leaves the parts that you want overhand the picture
sticking over the edges.
6. Go to the Select Menu and choose inverse. Then press the delete key to erase
those outside areas. Click on the eye icon next to the background layer to hide
it from view. Deselect the areas.
7. In the Layers palette, hold the Control key and click on the New Layer icon
on the layer menu. Use the rectangular selection tool to draw a rectangular
selection that is slightly larger than the remaining background, one square all
the way around should be adequate
8. Click on the foreground Color selector and choose a very light gray color.
Fill the selection with the light gray.
9. Duplicate this layer by pressing Ctrl J. Then switch the Foreground color to
black and fill the gray with black. Drag this layer underneath the gray box
layer in the Layers palette making this layer 4 under layer 3.
10. Go to the Filter menu and under Distort and then Shear. Drag the center of
the line one square to the right.
11. Press “v” to switch to Move tool and drag the black layer down to the left
until the corners peek out. Go to the filter menu, select Blur and Gaussian
Blur. Enter 3-6 pixels depending on the resolution of your original picture. In
the Layers palette, adjust the Opacity of this layer to 30% and change the layer
blend mode to multiply.
12. Click on the top layer then choose Drop Shadow from the Layer Styles menu.
In the dialog, lower the Opacity to 30%, set the Angle to 0%, Distance to 30 and
the Size to 10.
13. From the Layers menu choose Merge Visible.
14. Click on the Background layer and fill it with white.
15. Click on Layer 2 and press Control-T to bring up the Free Transform bounding
box. Move your cursor outside the bounding box and swing the box around to the
right or left a little.
16. Hold the Shift-Alt-Control and grab the top-right or top-left corner and
drag down to add perspective. Press Return to finish.
Obviously the Mac commands are slightly different but you get the idea.
