Extruding Object with Photoshop

This tutorial will show you how to make your object pop out of your frame using photoshop CS. Just like the image below:

Step1. Open your desired image

Step2.

Create a new layer, using your marquee tool, create a square that will overlap your object. Once you have created your square, invert your selection (select>inverse). Fill the area with your desired border color.

After your border has been filled with the appropriate color, drag the border layer to below your picture layer

Step3.

Select the picture layer. Hold and select the border layer to load the border layer's selection.

With the selection active and the picture as the current layer, create a layer mask (layer>layer mask>reveal selection). This will mask the picture where the border is present.

Step4.

Select the layer mask and with the brush selected, begin to paint away the area of the mask that covers your object that you wish to extrude. This is a bit tricky, so take your time and get it right.

Step5.

Now, create a new layer and move it to below the picture layer but above your border layer. Make sure that black is your foreground color. Using your brush tool (make sure you have a hard brush), start painting the area that is going to extrude. Basically, you're creating a shadow. After you have created the shadow, apply a gaussian blur to the layer (filter>blur>gaussian blur)

Step6.

Use the move tool, offset your shadow so that it creates a sense of depth in the picture

Done!
