August 13, 1880. J THE PHOTOGRAPHIC NEW?. 391 Vander Weyde studio, and that of the London Stereo- I Referring to the remarks on new emulsions in our issue sennie I omnanv\ Ar +n Ige +he I.nvnoronhic nrnrnec wi+k 1 Hotes. Mounting dry is usually resorted to now-a-days in pho tographic establishments where large quantities of cartes and cabinets are produced. The prints prior to trimming are coated with starch and permitted to dry. They are then cut to proper size, and carried into the mounting room, A card is damped with a sponge, a print placed upon it, and the two sent through rolling press. Prints are mounted most quickly and efficiently in this way, but the method will not answer where there are wide margins ; for in this case picture and card cannot be well put into the rolling press together. When collodion emulsion came into general use some years ago, several photo-chemists experimented with stained films, employing for the most part chlorophyl and eosine, in order to secure plates of a green and reddish hue, and with these pictures of the solar spectrum were secured. It was averred by some that films so tinted were impressed by certain regions of the spectrum that were without action upon non-tinted plates, while other experimentalists, again, maintained that it was simply the bromide or particular condition of the bromide in the collo dion that accounted for the phenomenon. Gelatine plates may be easily tinted, and it is now suggested that films should be coloured, for the purpose, if possible, of per mitting their development under less rigorous conditions than at present. How a film can be so tinted as to protect it from light during development, and still have its photo graphic properties unimpaired, is a problem, however, that has yet to be solved. even after long continued development, the brighter parts of the picture do not become too hard (as in the case of long developed gelatine plates), but remain soft and harmonious. For this reason, as Dr. Vogel asserts, clouds in landscapes are easily obtained with his emulsion. An other quality, Dr. Eder remarks, is that Vogel’s plates, when dry, can be easily retouched with lead pencil, even before varnishing. quality of the light without augmenting in any way the expenditure of gas, and, provided with a blue glass or other suitable screen, there is no need to fear inconvenience to the sitter. The advent of electricity for lighting up streets and bridges has caused a wonderful stride to be made in the matter of gas illumination, and we have now at our dis posal burners whose dazzling brightness almost seems to equal that of our electric lamps. At street corners and crossings in nearly every town in the kingdom these last successful efforts of our gas engineers are to be seen, and photographers who know the capacity of gelatine films will have no doubt as to there being here ample light at one’s disposal for the taking of portraits in a few seconds. Five pounds is the cost of the W igham burner employed by Mr. Laws, but if there were a demand for such things for photographic studios, there is little doubt that still cheaper and better jets would be the result. Mr. Laws has been good enough to promise a few more details in respect to gas-meter, cost of gas, and expense of reflector and glass screen, and these we shall lay before our readers at the earliest opportunity. once more the description wo have given, they will find most of their questions answered already. In our “ At Home,” we placed above all things the point of simplicity, and as much as said that Mr. Laws’ apparatus was scarcely worth looking at, it was so stupidly straightforward. It is a multiple gas-jet, standing in a Dutch-oven shaped re flector, with a screen of blue glass in front to prevent the light and heat annoying the sitter. Mr. Law’s, as we have said, has tried naphthalising his gas; but, nevertheless, the remarks of an esteemed “ Occa sional Correspondent ’’ in our last week’s issue are well worth taking to heart, for it is very certain that, during the coming winter, gas illumination will be resorted to The hands of the mounter always remain clean under these circumstances, for they touch nothing but the damp sponge, and a cloth kept close by permits him to dry his fingers if necessary. It is a bad practice, as most of our readers know, to mount prints, or at any rate portraits direct from the washing water; the distortion of the features from the effects of the wet paper stretching is sometimes exceedingly marked when this plan is followed. Eosine, the red dye stuff which has been most favoured by photographers in this connection, was employed, it may be mentioned, to decide a vexed geographical contro versy some years ago. The most minute trace of eosine in water may be detected by its fluorescence, and for this reason the pigment was chosen to settle the question whether or no a certain stream was a tributary of the Danube. A large quantity of the material was thrown into the river near its source, and then at the spot in dis pute the water was tested. This was found to exhibit distinct fluorescence, proof positive of the stream being the same as that which received the eosine. In laying the foundation stone of the Temple Bar Memorial on Tuesday, there were deposited in an urn photographs both of the Memorial and of the recently demolished Bar, pictures that the Daily News hopes “ have been executed by the most permanent of 1 permanent ’ processes.” Certainly, if photographs are in future to be put with coins of the realm, newspapers, and other records usually deposited with foundation stones, they should be of the most lasting character ; indeed, only pictures burnt- in upon enamel or porcelain ought to find a place in such depositories. in many studios. If it pays to employ electricity and to keep an engine going for portraiture (as in the case of the ! scopic Company), or to use the Luxographic process, with ’ 30th July, Vogel writes to us that he now prepares its somewhat complicated illuminating arrangement,, . 2' a 1 r many photographers will surely deem it worth their while | emulsion of the same sensibility as the best plates ot to spend ten or twenty pounds to fit up a gas-burner Wratten and Wainwright, and that his plates dry, after proper to the taking of pictures in their glass rooms.
