IDAT211 - Channel 4, an example

#bdat Whilst considering the concept of perception and cognition and the way in which our perception can be utilised, I began to try and think of examples that demonstrated these concepts other than those shown to us in the lecture.  It occured to me that the Channel 4 idents are very much relevant to this as they are designed to utilise our perception in order to give the channel an identity.  An example of the idents is shown below:

This is similar to the Charlie Chaplin mask optical illusion shown here:

At a very specific point in time the 4 is seen in the image and then instantly disappears because of the angle that viewer sees the image from.  This demonstrates the discovery and loss of meaning in the image.  This and the other channel 4 adverts have been built specifically to have this effect in which the ident is not understood until a certain point and then the meaning is lost again.  By doing this the ident keeps the viewers attention and ensures other information such as that of the voiceover is also recieved.
