Manchester and J T Chapman - exhibition

Following recent discoveries in the John Rylands Library Special Collections, UNDEREXPOSED is an exhibition in Collaboration withThe Museum of Science and Industry, celebrating the life of one of Manchester’s early photographic pioneers, J.T. Chapman.

Chemist, inventor and photographer, Chapman invented some of the processes that were to become standard in early photography. However, he is widely omitted from history books as he published his formula under the pseudonym ‘Ostendo non Ostento’ (I show, not boast). Working from Deansgate, Manchester, Chapman also invented and sold his own cameras and projectors.

The exhibition also showcases a selection of glass plate negatives, recently discovered and linked to the Langford Brooke family of Mere Hall in Cheshire, which have been cleaned, re-housed and digitised by CHICC.

CHICC is The Centre for Heritage Imaging and Collection Care, a JISC funded project to develop a Centre for Heritage Digitisation, based within the University of Manchester.

The John Rylands Library will be holding a series of events associated with the exhibition, for more information please contact 0161 306 0555 or email

The exhibition is at the John Rylands Library, Crawford Room, from Wednesday 29 September to Sunday 28 November. Admission is free.

There will be a curator tour on Wednesday, 3 November between 1200-1300 and 1400-1500, both of which are free.
