Here are a few ways to make intentional Glitched Images.
Text/Hexadecimal file editor:
Text/Hexadecimal involves editing the code of an image in an unnatural state. Hexedit
works great, as does Note Pad++
or any text editor, like Notepad or it’s Mac and Linux equivalents.
Generally, Text/Hexadecimal editing only works on certain types of image files such as BMP, TIF, photoshop RAW. Using this type of editing on JPG or PNG file will most likely break the file because fucking with the code of an image is highly destructive, and due to the heavy file compression of JPG and PNG files, they are incredibly fragile because each bit is important. Even a tiny glitch in the wrong place can have a major effect. Non-interleaved files always work better than interleaved files due to the way RGB color values are stored in the code.
Always save an original of the file, and only glitch copy’s.
After opening up the right format of image in an editor, the fun can begin. Image files have a header that declares what type of file it is and other important stuff. If deleted this will usually break your image. The header is usually a few hundred lines down. The best way to find out is by trial and error.
Once the image is loaded into your editor, and the header is located, its time to start fucking around. Try going to a random spot and adding in text, copy and paste sections, delete chucks of code, find and replace certain numbers, symbols, or characters. Forcing errors in the code and editing it incorrectly. With time, experiments will become methods to the madness that will be personal mastery of glitching. After the edit, re-save the file, and admire the results.
Sonification is the act of converting data into sound. It is an very broad field, but using Sonification techniques to create art, is a well known way of DataBending. In particular opening up an image file into a WAV editor such as Audacity, Voice, or Goldwave.
A WAV is an application for recording waveform audio. A waveform is like a digital representation of a sound wave. When one rips a CD to MP3, it’s actually ripping it to WAV first, and then encoding mp3s based on those WAV’s.
Open up Audacity. and and go to File > Import > Raw Data. Under Encoding use either U-Law or A-Law, but remember your choice.
With the file being shown as a WAV form, one can go about editing using similar techniques as the text/hex editing, including copy/paste and deleting. But one also has the added option of using a variety of different audio editing tools including adding Echo, Amplify, Bass Boost, and a huge variety of other effects. They will sort of work like filters in Photoshop.
Once happy with the modifications go to File > Export. Choose a new location for the image and type in the proposed new file name. Change the file format to Other Uncompressed Files and then click on the Options button. Change the settings to match U-Law if U-Law was imported, or A-Law if A-Law was imported. Set name add the appropriate extension to the file (.JPG, .RAW, .TIFF). Save the file and once again and admire the results.
Hope this was insightful. Love the Glitch.
