A photogram is a photograph made without a lens or camera: objects are placed directly on top of a sheet of photographic paper which is then exposed to light. Where the objects obstruct the light, the paper remains unexposed (light in tone), while the rest darkens through exposure.

Paper or material-based paper type used in printing black and white images from negatives (C-type). Available in all surface finishes, this thicker paper has a high-quality texture, gives an excellent finish, and adds ‘depth’ to the image through the faint weave of the paper/fibre.

Pigment, unlike dye, is a powder made up of tiny granules that will not dissolve completely in solution. This means that pigment-based inks leave particles of pure colour bonded to the surface of the paper that they are printed on. The resulting images can thus appear very rich and physical, densely saturated in colour –…

Digital printing that produces images directly on to the material (e.g. canvas or special paper surfaces) from a digital file through a stream of very fine dye drops controlled by the computer system. (See also Giclée prints)

Polaroid is a manufacturer/trademark of a photographic system which gives ‘instant’ prints, by which film, paper and developing solution are combined in one unit. As soon as the film/paper is exposed the image begins to develop, developing fully within a maximum of 5 minutes. All Polaroids on eyestorm have been professionally ‘stopped’ and removed from their…

A positive is, obviously, the opposite of a negative – that is, it is an image which is not reversed. Positive images are made through a double negative: silver salts react to light producing a negative which, when projected onto photographic paper (more silver salts), produces a positive.
