Even if for my works I spend most of my time looking for ways to corrupt image data, one of my biggest fear is losing my works for unwanted data corruption and obsolescence. Especially in matter of proprietary image file format, like Adobe that owns .psd and .pdf and Microsoft that owns .bmp. Also, I fear that some file format will become obsolete and softwares won't be able to read that file anymore as they will not be programmed to read that file anymore. Obsolescence is one of the biggest fear of people working with new media. If a media becomes obsolete also the art made with and working with specific machines will become obsolete too. A photo can get old but it will be forever if preserved well. Digital images are very vulnerable and fragile, data corruption can happen so easy. Digital is cool but it is not safe to keep important works, memories and documents.
