The Weber-Fichner law, which shows that the relationship between a stimulus and perception is logarithmic, is applicable to modern media. A gain in resolution of a low resolution picture is more easily seen than the same gain to a higher resolution image.
Goethe University Frankfurt researchers have found indications of the Weber-Fichner law in the size distribution of Internet files. Studying more than 600 million files, the researchers found that approximately 58 percent led to image files, 32 percent led to application files, 5 percent to text files, 3 percent to audio files, and 1 percent to video files.
The researchers plotted the size of each file type against the number of files to receive the files' size distribution. The researchers found that the audio and video file distribution followed a log-normal curve, which is aligned with a logarithmic squared-type relationship, while the image files follow a power law distribution compatible with a logarithmic association. "[This] strongly indicates that [the distributions] are determined by the underlying neurophysiological limitations of the producing agents," says Goethe University researcher Claudius Gros.

That is quite interesting. I did download their data from http://www.findfiles.net /public, let's see what if more is to be disovered in this data file.
