1. Open up a 500×500 white document

2. Create a new layer and select the Rectangular Marquee Tool

4. In the picture above, the circle is placed on the top left and bottom right of the square logo, try to do the same thing in your picture.

Now choose two colors, a foreground and a background color – I chose “#727272” & “#E4E4E4”

Now choose the gradient tool and use these settings

5. CTRL + CLICK on ” Layer 1 ” so it selects the layer and then click on ” Layer 2 ” and goto Select -> Inverse and hit the DELETE key.
