The document provides a 10 step guide for creating a multicolored box design in Adobe Photoshop. It instructs the user to open a photo with a solid background, add boxes of different sizes and gray tones to multiple layers using the rectangular marquee tool and fill options, then change the blend modes to overlay. It also provides steps to combine the box selections, copy the selection to its own layer, add a white background layer and drop shadows. The guide concludes by adding a radial gradient to serve as the new background.
