These devices, with their automated and computerised components

Two scientists from the University of Surrey are on a mission to help us make the most out of our digital cameras.

These devices, with their automated and computerised components, represent the technical pinnacle of photography’s 200-year history - and newer, cheaper technology arrives every year.

"But it’s still remarkably easy to take a bad picture," says Dr Radu Sporea.

One key step that is often overlooked, Dr Sporea tells me, is to think about where you take the photo from.

The offences took place in 2012-13 when Fox, 26, was a teacher at the Royal Masonic School for Girls in Rickmansworth, Hertfordshire.

Fox will also be added to the sex offenders register for 10 years.

'Reputation in tatters'

The court heard Fox exchanged hundreds of “sexually explicit” messages with the girl after they met in November 2012.

A few months later they developed an “intense” bond that involved kissing and later sexual touching, the court was told.

The relationship was discovered in August last year when a revealing email was printed out inadvertently and seen by the parents of the victim, who cannot be named for legal reasons.
