Photography, by its very nature, is a visual medium. It’s the capturing of an image on film using light reacting with chemicals. It’s all about the visuals, the look, the composition, the colours and the tones.

It might surprise you to know then that an exhibition of photography with a difference took place in the Ukraine recently. This exhibition was different because the photographs were actually for the blind.

The photographs use a unique piece of software that takes a photographic image and traces over the lines in the detail. It then manages to create an embossed version of the picture so that it can be touched, and experienced.

This makes the photos ideal for the blind to experience because they are able to follow the embossed lines with their fingers and ‘see’ the image as though it were written in Braille.

You can see examples of the art on the BBC website.
