STEP 2: From Image menu, Select Canvas Size. We will first create the outer frame of the picture, which will be 1 pixel wide all around the picture and in solid white color. Take the initial size of your picture and add 2 to both width and height – in this case, the original image dimensions were 1200×492. On the bottom of the screen where it says “Canvas extension color:”, select “White” from the drop-down, then click “OK”
STEP 3: You should now see a solid 1 pixel wide frame around your picture. Now, let’s go ahead and create the outer frame. Again, go to Image Menu, Select Canvas Size in Photoshop, but this time, add 30-50 pixels (depending on how large you want the outer frame to be) to both width and height of the image and select “Black” from the “Canvas extension color:” drop-down, then click “OK”
STEP 4: You all set! The third step will create a larger outer frame in black color. Here is the results.
Obviously, you can experiment with different widths and colors for your photographs. Just bear in mind that you will always have to add an even number to both width and height, since the number of pixels have to be divided equally from top to bottom and from left to right.
