This is based on a variation of databending that I call cosine bending. This involves manipulating the parameters of the discrete cosine transform algorithm used to perform lossy compression on a JPEG image. This may sound rather advanced and convoluted, but it really just means saving a JPEG at a very low quality to produce glitch effects. I did that with one of my old urbex photos, and then I messed with the colors in GIMP and applied some pixel sorting to get the image shown here. 😗
