1. Open your photo.

2. Duplicate your photo, press CTRL+J. Resize your working space, make it a little bigger than your photo size. Click the Crop tool and drag the entire area then on the bottom right corner, click hold and drag the transforming point. Press ALT key while dragging to constrain a proportion. Then press ENTER when you're done.




3.
Change the color of your background, anything but not white. Click the Add Layer Style button at the bottom of the Layer palette ans choose STROKE.





4. Do the following settings for Stroke:



Take note that this setting is only good for the size of the photo I used in this tutorial. If your photo is smaller or bigger that what we are using here, just adjust the settings.


5. Click also the Drop Shadow in the Layer Style and just leave it to the default settings: Click OK when you are done.




6. This is now the photo. It looks fine and satisfying but to add a little depth, right click on the Effects on the layer and choose Create Layers. This will create a separate layer for the Stroke and the Shadow.







7. Select the
Drop Shadow layer and click the Move tool , rotate the shadow a little bit like this. Then press ENTER when you already positioned the shadow.






8. Select the Eraser tool and start erasing the top part and the left side of the photo. Make sure that you have selected the Drop Shadow layer.
 




You can lower the shadow opacity to 80%. So this is now the photo:
