No. 56.— 1905.] PHOTOGRAPHY OF COLOUR. 443 
By far the most remarkable results are, however, un- 
doubtedly obtained by this three-colour or trichromatic 
process when applied to the production of well constructed 
stereoscopic transparencies. In such transparencies depth of 
focus being added to the natural form and colours, it is 
difficult to realize when viewing them through the stereos- 
copic instrument that one is not looking at the actual objects 
photographed. 
Larger sized three-colour transparencies are admirably 
adapted for fulfilling all those decorative purposes, such as 
window transparencies, lamp shades, fire screens, and other 
artistic uses for which hitherto stained glass has been the 
only available material. 
Another direction to which this natural colour photo- 
graphic process has already been applied with very con- 
siderable success is the reproduction of the paintings of old 
masters and other works of art. The firm of Sanger 
Shepherd & Co., already referred to as supplying all the 
necessary materials for this three-colour work, possesses a 
very fine series of replicas of the gem pictures. Such as those 
of Bentens, Turner and Landseer, and others contained 
in the London National Gallery, every shade of their mel- 
lowed tints being most faithfully reproduced within the 
dimensions of a small lantern slide. 
The walls of this noted Museum wherein we are now 
assembled are especially suggestive of three-colour possibi- 
lities. They are profusely decorated with admirably copied 
replicas of the frescoes and other wall paintings of the 
ancient cities of Ceylon. The time and labour involved in 
the production of these replicas has been enormous, and is 
beyond praise ; but an immense saving of this time and 
labour could have been accomplished with the assistance of 
the camera and colour screens. 
It has been suggested that this new development of colour 
photography may detrimentally affect the interests of the 
professional artist. It on the contrary places additional 
advantages at his disposal. Photography and Art stand in
