Photogram

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.

    A stencil is made up for each colour of the image and put over a fine fabric mesh that is stretched over a metal frame. The coloured ink is spread over the mesh and stencil and the ink falls through the stencil to the underlying material (usually an art paper) to produce the image. The…

  • Positive

    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.

  • Fibre-based paper

    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.

  • Toning & Titing

Toning can be used as an aesthetic decision by the artist, or it can also be used to improve the archival properties of a print….

    A sheet of transparent film coated with silver salts which react when exposed to light (usually in a camera). In black and white negatives, one layer of salts reacts to white light (the full spectrum of light). The result is a reversal of normal vision: the shadows are light, the highlights dark. In colour negatives…
