I think by 2100 the nanny state will have banned all forms of photography.

Know as the Photobition, addicts will become known as 'Foxtalbots' and forced underground to get their fixes. Electronic photography will not be possible as the state will be able to detect electronic emissions, and the manipulation of any imagery via computer monitored by the 'New Labour Spin-Doctor-Web', so cameras will be hand made items, crafted with passion, simple large format style units that can be dismantled and disguised as other items for ease of transport, and the medium of recording the image will be sensitised paper fixed with common salt.

Others will dabble like alchemists, to produce potions that will allow images to be recorded on other materials such as glass and plastic. And a secret sect known only as the 'Silver Halides' will develop an amazing process using silver halides, allowing lifelike images to be formed on a celluloid base. This process will allow incredible lifelike imagery to be stored in celluloid format, but the creation of such imagery will require great skill, images cannot simply be produced or amended electronically.
