Default Re: Digital hard copy?

Another interesting size ratio occurs with photography. Consider the area of a sensor collecting light. Take a few hundred shots and compare the area of CDROM or DVD it takes to store them on, and this is an optical to optical comparison.

It illustrates the difference in densities and the effects of coding, even if you're not using lossy compression.
