Creating slide backgrounds for use in PowerPoint is something that can use a little help from Photoshop. That’s because Photoshop has an amazing repertoire of tricks that makes creating backgrounds easy. One of the effects in Photoshop called Reticulation lets you achieve all these objectives. In olden days, Reticulation was the process of crafting metal by inducing heat through a torch – ending up with metal which is patterned into ridges, textures and emboss effects. Nowadays, of course only artists and craftsmen use the Reticulation process as most metal is machine made. Photoshop’s Reticulation filter tries to emulate this amazing effect.
