Royal Plates, made in Canada, afford the Canadian photographer a fairly complete range for general purposes.
First is the Royal, Special Extra Rapid, a straight plate of high speed with abundance of latitude, which has given uniform satisfaction in portraiture and the simpler forms of commercial work. We have spared no pains to maintain the quality, and today Royal S. E. R. is the mainstay of many photographers who have used them for years.
Next comes Royal Polychrome, a high-class orthochromatic plate, possessing speed with its color sensitive qualities. Polychrome is the favorite of quite a number of leading commercial workers, who find that it takes second place to none but a panchromatic, where color separation is involved. With a K2 or K3 filter, polychromes discriminate adequately between the colors that prevail in the general run of commercial work, but of course it is to be remembered that they are not panchromatic. Polychromes have also won a name for themselves in portraiture, under artificial or yellow lights, where their color sensitiveness has proved its value.
Royal Process Plates are invaluable for making copies of old photographs, where heavy stain does not exist, as well as in photographing printed matter and black and white subjects, where contrast and clearness are of the first importance.
The Royal line also affords plates for the lanternist. The Royal L. S. emulsion yields transparencies of beautiful brilliance and clearness, with a fineness of grain that will meet all requirements.
It often happens that a picture which seems just ordinary in black and white, assumes an added charm when reproduced in another color, and this is especially true of landscapes and other outdoor commercial photography. To such pictures a wonderfully realistic value can be given by using Artura Carbon Green, which produces rich Carbon effects in close harmony with natural coloring, by a straight ahead process of single development. Carbon Green is best printed by daylight, and care should be taken to use developer of proper strength.
Carbon Green is especially useful to the man who makes a specialty of high-grade photographic views and post cards, for the realistic tones will lift his pictures away above the level of the average work, and the public is always willing to pay the price for preeminent quality.To landscapes, river and lake views, mountain scenery and sunset pictures, Carbon Green imparts a richness that makes its use worth while.
When you are puzzled to explain the under-exposure of a negative made under normal conditions, on a plate with whose working you are familiar, don't be too quick to lay the blame on the plate, but rather look after your lens, for it is more likely that your lens is playing you false than that the plate has lost its customary speed. You know that dust will always find its way into the frame-work and bellows of your camera, and must be cleaned out if you would avoid dust spots on your negatives, but it is a fact that some of that dust lodges on the lens surface and should be cleaned off regularly. It often happens that lenses become coated with a sort of scum, formed of dust and moisture that has condensed on the lens. Scum of this kind is the cause of much trouble in the way of under-exposure, particularly in studios where there's a great variation between the temperature during working hours and the temperature during the rest of the day.
