PHOTOGRAPHIC SURVEY OF WARWICKSHIRE. 
Apr., 1890. 
SOME NOTES UPON A PROPOSED PHOTOGRAPHIC 
SURVEY OF WARWICKSHIRE. 
BY W. JEROME HARRISON, F.G.S., 
VICE-PRESIDENT OE THE BIRMINGHAM PHOTOGRAPHIC SOCIETY ; AUTHOR OF 
THE “HISTORY OF PHOTOGRAPHY;” “PHOTOGRAPHY FOR ALL,” ETC. 
( Concluded from page 70.) 
Documents, etc., Copied by Photography.— We must 
photograph not only places, but things. Old documents, 
seals, plans, maps, various objects of antiquity, rare fossils, 
etc. All these will provide food for the camera, and will add 
interesting pictures to our stock. One advantage of photo¬ 
graphy in this direction is that it enables us to bring together , for 
purposes of comparison, a series of objects which may be 
scattered in many collections. The facsimiles of documents, 
etc., obtained by photographic processes, are far more valuable 
than copies by hand can be. since they must be literal and 
unbiassed; errors in copying are avoided, and the evidence of 
the photograph is practically as good (sometimes, indeed, it is 
better, because clearer) as that of the original. 
Size of Photographs to be taken.—I fear it will be 
impossible to bind ourselves down to any definite size of 
negative. Perhaps it would be best to make the whole-plate 
size (8Jin. by 6Jin.) our standard. By the recent substitu¬ 
tion of celluloid films for glass plates, the weight of the 
photographer’s equipment has been greatly diminished; so 
that a wliole-plate camera with films, weighs no more than 
a half-plate camera with glass plates. 
By the use of cases or boxes to hold separately mounted 
prints, the difficulty of variety of sizes is largely avoided. 
If albums are made up, they could be of such a size as to 
hold one wliole-plate print, or two half-plates, on each 
page. 
For hand-camera work the usual size is the quarter-plate 
(4Jin. by 8Jin.); and for pictures of this size separate albums 
might be provided, or they might be mounted four on a page of 
the larger albums. It must be remembered, however, that it is 
easy to enlarge or reduce negatives, so that they could all be 
brought to one uniform size if that were thought desirable. 
Or it is even easier to enlarge or reduce the prints as they are 
made from the negatives, if we use bromide-paper, etc., for 
printing upon.
