If you are using a Photoshop RAW file then you have the option to make it headerless when you save it. In this tutorial, we explore datamoshing video in Avidemux (a free and open-source transcoding and video editing software) and the glitch visuals that can be created. If information in the header is changed it will break the image. A file header stores information like image size, resolution and color space. Photoshop RAW, BMP and TIFF files rarely break for me but you have to still worry about the file header. This means that changing the file too much will break the image and you won’t be able to open it back up as an image. Some file types are more fragile than others as well. JPEGs tend to produce small glitches that require a lot changes to the file’s plain text to get the results I’m looking for.
Each file type will produce different results.
To begin, you want to use the right image file format. Opening an image file in a HEX editor allows me to view the file in plain text and this is where I insert text from climate reports, news stories, or politicians’ quotes. Glitching images using a HEX editor is how I make the majority of my glitches.
