Sorry, no etymologies found.
_Platino-Bromide_ paper gives delicate platinotype tones, and where negative, paper and manipulation are in harmony, the prints obtained on this paper will be indistinguishable from good platinotypes in quality and attractiveness.
The latter, except under exceptional circumstances, are far better employed in the legitimate form of platinotype or other platinum paper; bromide prints toned with platinum will probably cost more, and will never have the absolute permanence peculiar to the platinum print.
Any one taking up platinotype and getting only weak prints would do well to look to his negatives instead of blaming the paper, as the high lights should be fairly dense, and the deep shadows nearly clear glass.
A thin negative is better printed by the cold bath process, but negatives should be good and brilliant for platinotype printing.
The platinotype has been still improved by Captain Pizzighelli, who devised the following methods of operating by which the impressions are obtained by the continuous action of light, that is, without development, thus rendering the platinotype just as simple as the ordinary printing-out silver process.
It offers a range of tone from deepest black to the most delicate of platinotype grays, which may be modified to give a fair variety of color effects where this is desirable.
The preparation of wood, canvas, etc., for the platinotype printing need not to be described; it suggests itself.
And it looks so nice as a frame for platinotype photographs.
The aniline process was published in 1865, by Mr. Willis, the inventor of the platinotype. (
