A Wave effect can apply color-based distortion to just one layer. Select the RGB channel you want to use in the Channels panel, and select All on the document. If the image has a lot of blue, for instance, separating the blue channel will yield dramatic effects. When attempting to add a glitch effect to an image, assess which of these three color channels is most prominent and which one could be shifted slightly in multichannel mode for good results. RGB channels are the primary means of pulling apart an image’s colors in Photoshop. The RGB (red, green, blue) channels in Photoshop provide a way for you to break apart the colors of an image and create color separation of your own.
#GLITCH EFFECT DRAWING REGISTRATION#
Old television sets and crystal displays were prone to coloration and registration errors that could give images a separated, fractured appearance. To create glitch art is to create intentional “accidents.” Like pixel art, which draws inspiration from retro technology’s limitations, glitch art takes the shortcomings of the previous era’s technology and transforms them into haunting, enigmatic imagery.
Glitch art is the deliberate duplication of old media’s mistakes. Actual distortions in retro media like VHS were accidental, and modern technology has made those accidents obsolete. To create these images, a modern artist cannot rely on fraying tape or failing cathode ray tubes. Just as Eno predicted, tracking errors and the bent lines of degraded analog media are now an aesthetic artists are using in their work. “CD distortion, the jitteriness of digital video, the crap sound of 8-bit - all of these will be cherished and emulated as soon as they can be avoided.”
“Whatever you now find weird, ugly, uncomfortable, and nasty about a new medium will surely become its signature,” artist and producer Brian Eno wrote in his 1996 book A Year with Swollen Appendices.
