Further Tools: Photography |

Art has always contributed a lot to disinformation.
Many modern tools for disinformation are used in art/photography.
 Harold D. Lasswell once stated that propaganda was cheaper than violence. Today this is no longer true. Technology has created new tools for propaganda and disinformation - and they are expensive. But by now our possibilities to manipulate pictures and stories have gone so far that it can get difficult to tell the difference between the original and a manipulation.
Trillions of photographs have been taken in the 20th century. Too many to look at, too many to control them and their use. A paradise for manipulation.
We have to keep in mind: There is the world, and there exist pictures of the world, which does not mean that both are the same thing. Photographs are not objective, because the photographer selects the part of the world which is becoming a picture. The rest is left out.
Some tools for manipulation of photography are:
Some of those are digital ways of manipulation, which helps to change pictures in many ways without showing the manipulation.
Pictures taken from the internet could be anything and come from anywhere. To proof the source is nearly impossible. Therefore scientists created on watermarks for pictures, which make it impossible to "steal" or manipulate a picture out of the net.

Bandwidth
The bandwidth of a transmitted communications signal is a measure of the range of frequencies the signal occupies. The term is also used in reference to the frequency-response characteristics of a communications receiving system. All transmitted signals, whether analog or digital, have a certain bandwidth. The same is true of receiving systems.
Generally speaking, bandwidth is directly proportional to the amount of data transmitted or received per unit time. In a qualitative sense, bandwidth is proportional to the complexity of the data for a given level of system performance. For example, it takes more bandwidth to download a photograph in one second than it takes to download a page of text in one second. Large sound files, computer programs, and animated videos require still more bandwidth for acceptable system performance. Virtual reality (VR) and full-length three-dimensional audio/visual presentations require the most bandwidth of all.
In digital systems, bandwidth is data speed in bits per second (bps).
