True and Accurate

There's been a lot of discussion lately about compression and if a compressed photo or video of a scene "represents a true and accurate version of what really happened."

If the compression scheme, such as JPEG, throws out details and preserves the overall look and feel of the scene in order to save space ... does it accurately portray the scene that it captured? What about those DVRs that throw away ever other line of video in addition to employing some form of compression? If you are to present such files in court, and you don't know what's been lost, do you feel comfortable introducing the files as evidence?

I'd be interested to know what you think. Send me a note or post a reply.

Enjoy.
