Entropy + Redundancy.

Redundancy.

Redundancy is what is predictable or conventional in a message, it is the result of high predictability.

I feel for a girl band this image is very redundant, the image is of the artists in sexualised poses, this is redundant because its very predictable, to show how predictable this image can be, I've included some more examples.

Entropy.

Entropy is what is unpredictable in a message.

A picture of a rose would normally be considered to be very redundant, however by changing the image, we can make it more entropic, here is a beautiful photograph of a rose edited into different colours, although the  rose is redundant, the colours on the rose are very entropic and are what is unpredictable in the message.

Subjective?

If the below album art was for a girl band it would be considered very entropic, as it does not fit in with the conventions of the genre, however on hearing that the band is an indie rock band, the image immediately becomes more redundant, as it is something we would expect from an indie rock band.
