Photoshop tutorial: Design a pop-up illustration

Step 2 Now separate the artwork into layers using the Magnetic Lasso tool with the Edge Contrast set at 10%. Look for natural horizons within your artwork. With the Selection tool active, right click and select Layer via Cut. This will separate your selection onto a new layer. Repeat that a couple of times until your artwork is divided. There’ll be gaps in your artwork at this stage but don’t worry about those for now, they can be corrected later.

Step 3 These layers will form your ‘pops’. They will need tabs to stand up, which will be glued later to your base. Select the Line tool and set it to a width of 10px. Draw two simple tab shapes at the base of your artwork. Holding down Shift while you click and drag will snap the line horizontally and diagonally.

Step 4 To make the base, create a new landscape A4 canvas at 300dpi. Next you will need to mark out the centre fold. Go to View > New Guide and set it to 50%. This will place a guide in the centre of your canvas, from which all your pops will function.
