38 • May 2017 • S I G N & D I G I T A L G R A P H I C S DIGITAL PRINTING AND FINISHING DIGITAL GRAPHICS An image captured directly from a scanner or digital camera contains a sin- gle layer called Background. A background does not support opacity or blend modes. It's best to convert it to a layer (Layer > New > Layer from Background…) and then duplicate it (Layer > Duplicate Layer…) to make an identical copy. It's always a good idea to name the layer after the blend mode you are to apply—in this case we'll use the blend mode Linear Light. Click the new layer and choose Linear Light from the Mode menu. Linear Light produces a hyper-saturated look, but it can blow out lighter areas if applied with too much intensity, (see Figure 5). Duplicate the layer again. Name the new layer Hard Light, and assign the Hard Light blending mode. The image contrast is further enhanced and the col- ors become more saturated but areas are still blown out. Let's push back a little. Figure 5: A Linear Light blend mode is applied. Figure 6: The Hard Light blend mode is applied, the opacity is adjusted and a layer mask is added to localize the effect. Figure 7: A lackluster cacti and flowers can be improved. Figure 8: A Vibrance adjustment layer is applied.
