Part 2

The unveiling of the Daguerre memorial during the convention, to be permanently placed in the Smithsonian Institution, will be one of the special features. This memorial is the gift of the photographers of America. The fund is raised by one or more dollar subscriptions from the photographers (which it would be well for you to send in your subscription at once to one of the different committees, and help the matter along, and do honor to the man who first brought to light this noble profession of ours).

You will miss it if you _fail to come_. There will be some of the finest specimens of American photography ever exhibited, as well as European. I have the promises of exhibits from all the leading photographers of the world.

_Rules and regulations, list of awards, entries for competition, etc., will be mailed on application._

Is not this association worthy of your support? Any photographer of good moral and professional standing is eligible. If not already a member, lose no time in uniting yourself with an organization already a power in the land. It has stood the test of time (eleven years), and has a creditable standing throughout the length and breadth of the civilized world.

To become a member, send five dollars if a proprietor, and two dollars if an employé (which pays entrance fee and dues for first year), to the treasurer, G. M. Carlisle, Providence, R. I. If already a member kindly remit your dues ($2.00), and by so doing avoid waiting your turn at the entrance when you arrive at the convention, as none can be admitted whose annual dues remain unpaid.

EXTRACT FROM CONSTITUTION.

ARTICLE II., Section 4.--The annual dues become payable on January 1 of each year, and any member failing to pay the same prior to the adjournment of the annual convention shall forfeit his right to membership, and can only be reinstated on payment of an initiation fee ($3.00) and ($2.00) dues, $5.00, as provided in case of admission of new members.

Become a member and get the benefits of the art lectures, practical talks, and a grand exhibition of photographic productions and stock exhibit. Fraternally yours,

D. R. COOVER, _Secretary_.

[We expect to publish, in our next number, an additional article on this subject, from the pen of the president, J. M. Appleton, which will reach our subscribers in ample time for the convention.]

The average newly-fledged photographer wishes to begin before breakfast. The barn or the back-yard fence is good enough for him, and if nothing else alive is in sight, it is easy enough to try it on the dog. Few dogs, however, have a proper sense of the responsibility of being photographed. After everything is carefully arranged, they get up and want to go home. Sometimes they remain silent until the picture is started, when they begin to stroll around and make eight or nine dogs on the plate; or they sit still and only wag their ears, until the negative shows something like a halo of ears. This would give a professional photographer much worriment of mind, but the amateur is generally wise enough to see that his failures are the funniest things he has.--_Photo. Times._

ORTHOSCOPIC PHOTOGRAPHY.

It is well-known that there are a large number of coal-tar color products, which have the property of causing an orthoscopic action on the ordinary sensitive dry plate, making the plate more sensitive for a certain color than the others; for instance, eosine is a superior sensibilator for green-yellow and yellow-green; cyanin, again, is especially sensitive for reds. Other products, such as rhodamin, cyclamin, methyl, violet, and others, generate in each instance an especial color sensitiveness.

While we have no deficiency in these mediums which answered for the greens and yellows, we have but few that answer for the various shades of red. Although Dr. Vogel has strongly recommended a mixture of chinolin red and chinolin blue (cyanin), the latter has two great drawbacks, viz., the salt is very dear, and does not keep. To overcome this difficulty I have instituted numerous experiments to replace the above with a more durable and cheaper medium. Among the various substances which I have tried, the mixture of indophenol and malachite green, has given me the most satisfactory results. Malachite green alone produces a strong sensibility to red, but the addition of the indophenol greatly enhances this sensibility.

In connection with the experiments with this solution, the interesting fact was observed that the sensibility for blue was greatly reduced in the brom-gelatine film, while green and yellow appeared in their true color values.

My proceeding is as follows:

(_A._) Dissolve 0.1 g. indophenol (napthalin blue) in 500 ccm. alcohol.

(_B._) Dissolve 1 g. malachite green in 200 ccm. water.

The latter solution is heated to about 70° c.

In the meantime, prepare a solution of 10 g. doppelt chrom sauris kadi in 100 ccm. water, at a temperature of 70 to 80°, then pour this to the hot solution of malachite green.

This mixture is kept hot for half an hour and then filtered, the precipitate which remains on the filter is now washed in several waters, and finally again dissolved in a solution of

Alcohol 250 ccm. Chinin sulphate 0.8 g.

The latter is first dissolved in a little alcohol by heating, then the volume is added to until the amount is reached. The filtered fluid has a beautiful greenish-blue color. This forms the stock solution.

To sensitize the plates, make the following bath, pour in graduate:

Indophenal solution (as above) 4 ccm. Malachite green (stock solution) 4 ccm. Water (distilled) 600 ccm.

Pour 60 ccm. of this solution in a tray (13 by 18 cm.) cover the plates and soak 2 minutes, keeping the tray in constant motion. During the operation all red rays must be carefully excluded; then the plate is drained and dried in absolute darkness.

Plates so treated are much quicker than when in their normal condition. They give the reds in their true color value, even through an intensive yellow color screen. Even this extreme color sensibility can be enhanced with the use of a “supplementary-ray filter” (“Ergänzungs-Strahlen filter”), which is made from a substance which absorbs all colors except the reds and yellow. Gelatine, dyed by soaking in a erythrosin solution, furnishes an excellent Ergänzungs-Strahlen filter, which is used in connection with the usual yellow color screen

PHOTOGRAPHY IN ROME.

The _Bollettino_, a journal published every two months in Rome, and the chief organ of those interested in photography in that city, gives the result of the last election of members of its Photographic Society as follows: Adler, Dottor Vittoria; Intriglio, Avv. Benedetto; Tenerani, Cav. Carlo; and of the correspondent members--Calvaria, Cav. Avv. Giuseppe, of Castellamare di Stabia; Daniele, Oreste, of Catania; Garzia, Oronzo, of Maglie; Hermans, Charles, of Brussels; and Orsini, Marchese Antonio, of Solmona.

The opening of the Second Annual Exhibition of Photography took place in the Palazzo di Belle Arti on the 2d of May, when a large number of members took part.

The display included landscapes and interiors, portraits, instantaneous views, film negatives, photo-micrographs, enlargements, flash-light pictures, architectural views, and representations of costumes taken in Morocco and in Sweden.

An excellent article on “The Duration of the Pose” begins thus:--“Formerly, when collodion occupied the whole field of photography, the first difficulty in the art was the preparation of the sensitive surface. Now that the preparation has undergone a radical change, passing into a branch of industry, that first difficulty has vanished, and there has succeeded to its place the duration of the pose, the exact determination of which has over the resulting picture an influence as great, and possibly greater than formerly, seeing that in the very short poses of the present time even a little error has a value of relatively greater importance.” The article goes on to say that the duration depends (1) on the sensitive preparation, (2) on the actinic power of the light, (3) on the object, (4) on the diaphragm, and (5) on the distance. Thus, if it were required to represent by an algebraic formula the conditions governing the pose _t″_, we should have--

t″ = k. P. L. O. d. D.

where k is the invariable constant.

The article, which is too long to translate, is written by A. Roncalli. It is succeeded by a short notice of the effects of the Schippang varnish upon collodion enlargements. This article, written by Ab. F. Castracane, makes mention of some unhappy results of the use of this varnish on some of his own pictures. After this comes a letter from Sac. D. Ratti, on halation, or _aureole_, as the Italians call it. Then a paper on the development of instantaneous negatives and on the toning of aristotype paper, by Bne. T. Melazzo. Various notes and receipts, with a bibliography and a short notice of the illustrated supplement, complete this interesting number. The illustration is that of a moonlight effect, the negative by A. Ducros, the phototype by Danesi, of Rome. “To obtain this picture,” says the letter-press note, “it was sufficient to set the machine against the setting”--pardon the indiscretion; I was about to add sun--“and to remove the cap. But, before this is done, that certain fifth sense has to be taken into account, without which,

‘Non licet adire Corintum!’

and Signor Ducros, profound and advanced artist and photographer as he is, possesses this fifth sense, and uses it in a masterly manner.”--_Photographic_ (London) _News_.

AMATEUR EXPERIENCES.--IV.

If any one wants to become thoroughly acquainted with the weaknesses and frailties of humanity, just let him become a camera carrier, in “all that the word implies,”--and he will enter a school, wherein he will learn more of the different phases of human nature in one lesson than he has during the last ten years of his life. No other vocation, if we except that of the live newspaper reporter, offers the same advantages in this biological study. Varied indeed are the experiences and vicissitudes of the amateur photographer, whether the camera bearer carries the latest Universal, with aluminium mounting, or rejoices in a Premium Pinhole outfit, he experiences the same annoyances and disappointments. Ignorant and unreasonable people are sure to be met with on an outing, and, worse than all, he has frequently to suffer for the sins of some rude member of the guild who has been there before him. Experiences like these are but too apt to discourage persons of a nervous or sensitive temperament; the picture, however, is not all shadows. There is often a bright side for the camera bearer, especially if he be susceptible of the humorous. Photographically speaking, the writer, in addition to such annoyances as double exposures, unaccountable fog, forgetting to draw the slide, put plates in the holder, or take the cap off, to say nothing of neglecting to insert the stop, has met with many rebuffs and disappointments on his outings, through meeting with ignorant or unreasonable people, in all such cases his rule has been always to look upon the comical side of the situation, and try to achieve his object, bringing into play his common sense, tact and knowledge of human nature, generally with the result of obtaining the coveted negative.

The trouble, however, does not always lay in the strangers we meet in our travels; the fault too often is with the camera bearer. There is a class of persons, largely represented among the guild of amateur photographers, who presume entirely too much on their wealth or social standing, and who at home pride themselves on their good breeding and polite manners, claiming to be within the so-called exclusive social circles or sets; yet they no sooner get away from the restraint of their immediate surroundings, such as a photographic outing affords, than they seem to forget that at least a little courtesy is due the strangers on whose premises they trespass. The dweller in a picturesque tumble-down shanty, or custodian of an old colonial or religious land mark, no matter in how humble circumstances of life they may be, have rights guaranteed them under the law, which even the exclusive amateur is bound to respect. One specimen of this kind will often spoil the game for all amateurs for some time to come. We will give a few instances which have come under our notice.

Early last spring two prominent members of the Quaker City Camera Club concluded to photograph an historic old church in one of the German counties (so-called) in our state. The place was rather difficult of access, being away from the usual lines of modern travel, so extensive preparations were made. The day proved all that could be desired. A team had been telegraphed for, and met the pair at the nearest railroad station. When the spot was reached the outfits were quickly unpacked and set up. No permission was asked, nor notice was taken of flower-beds trampled over, or other damage done. Then the bell of the parsonage was rung,--the clergyman answered the call in person. The spokesman, great in his own importance, asked for the keys of the church, as they wished to photograph it. The dominie answered, with an unmistakable Pennsylvania Dutch accent, that the sexton lived about a half a mile down the road. The reply was, that as he had a key it did not suit them to run after the sexton. Well, one word brought on the other, and the parley ended with the clergyman saying, “You will please excuse me; I got no time to fool with such nonsense, and I can’t be bothered with opening the church for every fool photographer who chooses to come out here from town; please go about your business, if you have any.” The interview closed with the threat by the parson to use a hoe-handle over the next photographers who should come to bother him with their intrusiveness. Our two amateurs packed up their outfits and beat an ignominious retreat, going back to Philadelphia with temper ruffled and object unaccomplished.

A few days after this episode one of the twain, wishing to have some sport at our expense, suggested to the secretary of the Leopardville Camera Club the advisability of a trip to the adjoining county, and securing for him a set of negatives of the old landmark. We knew nothing of what happened, and consequently, owing to our innocence and unsophisticated nature, we unconsciously fell into the snare that our kind friend laid for us on the first fine day. We made an early start. We went merrily over hill and dale, not dreaming of trouble. When within half a mile of the church, we stopped at a roadside inn to water our horse and inquire our way. We remembered the hostler, who, while reigning up, caught a glance at our outfit. To our surprise, he broke out with, “Say, Mishter, vas you a fotegraf feller?” “Why?” we queried. “Vell, if you vas, tont go to der kärch up dere; der breecher letzt woch putty near broke zwei fotegraf feller’s het’s up.” Here was a revelation. Our nickel had been well invested. We made closer inquiries,--from the description, we at once recognized our friend from the Quaker City who had suggested our trip, and was no doubt chuckling in anticipation of a countryman’s discomfiture. After a few moments’ thought we continued on our way. We met the dominie, and when we got back to our home we had eight negatives, exteriors and interiors, in our satchel. In one of the latter the dominie appears in the quaint old pulpit. With our ten dollar outfit, by the use of civility, tact, and common sense, we had accomplished that in which our predecessors had so signally failed, mainly by not exercising the common civility due towards a stranger.

Another case which came under our notice but a few weeks ago: In an adjoining county there still exist several quaint old buildings, erected during the middle of last century by a religious community, and used by them until long after the Revolution. Owing to the curious architecture and proximity to a summer resort, the property is often overrun by visitors and sightseers, who run over the grounds, enter the houses, intrude on the privacy of the inmates, as if they had no rights of their own whatever, and in fact act as if the whole premises were public property. The custodian or trustee of the property is a plain country Dutchman, and keeps an especially sharp lookout for amateur photographers, as the religious sect to which he belongs frowns down portraiture of any kind. A few weeks ago a party of nine or ten persons, ladies and gentlemen, made a pilgrimage to the old settlement under the leadership of a well-known pulpit orator in Pennsylvania. Among the party were several amateur photographers. When the party arrived at the grounds they entered, without as much as asking permission, and at once made themselves at home within the premises regardless of the inmates. While the amateurs were setting up their cameras, the preacher was airing his knowledge of the religious doctrines of the community which flourished there in days gone by. While making these derogatory allusions, the party had been joined by a stranger,--it was the trustee, and who lost no time in introducing himself to the preacher. The two men were a study for an artist. The preacher, who prided himself on his fine physique, oratorial powers, and dignity, was the ideal picture of the petted fashionable preacher of the present day. The other, a man of medium height, bare-footed, unkempt; a straw-hat of last season’s growth, a shirt of unbleached muslin, a pair of overalls, which hung by a single “gallus,” completed his wardrobe; his language was pure and unalloyed Pennsylvania Dutch.

In appearance the two men as they faced each other were as diametrically opposite as the poles. The trustee, without any ceremony, asked the preacher what he was doing there; the latter, looking down at the speaker with contempt and scorn, and nettled at the interruption, curtly told him to attend to his own affairs. This was more than the trustee could stand, and he at once ordered the party to pack up and get out. This in turn was too much for the preacher; so, turning to the trustee, said, “My good fellow, you seem not to know whom you are addressing; I am the Rev. Dr. ----, of ---- Church, in Philadelphia, and I wish you to understand that you are in the presence of ladies and gentlemen, and I would advise you to take yourself off without ado, as your presence here is unwarranted, uncalled for, and distasteful to the persons present as well as myself personally; and further, your appearance is hardly such as would be permitted within the circles in which the ladies present are in the habit of moving.” During this speech the trustee stood with mouth and eyes wide open. The others of the party nodded approval as their spiritual leader was delivering himself. One of the photographers was trying to train his camera on the countryman, who had for a few moments stood speechless. But it was only the calm before the coming storm. With a bound the trustee kicked over the tripod and camera; then, turning to the preacher in an unmistakable attitude, told him in his rich German English, that he was on private property, tramping down a growing grass crop, and if he and his crowd didn’t pack themselves off at once he would arrest and fine the party for trespassing. “But, my good fellow,” ventured the now crestfallen preacher. “Don’t speak to me!” was the retort. “You claim to be a gentleman; maybe you try to be at home. But if you were one, you would know better than coming with a crowd on another’s place, where you have no business, without even asking permission.” “But, my good man, we are willing to pay you if--” broke in the preacher. “We don’t want your money. All I want is for you to go and not bother us. Or do you want me to show you the way?” All this was said in the rich vernacular peculiar to the locality. There was no help; the trustee was on his own ground. So the party retreated and filed singly over the old stile into the road. It would be hard to say which of the party felt the sadder as they wended their way towards their conveyance, the crestfallen preacher or the Rittenhouse amateur with his shattered outfit.

This was but another instance where a little courtesy and politeness would have saved humiliation and photographic disappointment.

A RECORD IN DEVELOPMENT.--Many amateurs are so fidgety about their dark-room and its appendages that we describe, both for the benefit of the finic and also for “those who go down to the sea”--in trains, how an extemporized traveling dark-room was successfully used by a member of the newly founded Croydon Camera Club.

In case the railway superintendent should reprimand the guard who connived at the measures adopted, we must perforce suppress the gentleman’s name, the date, and the station where the train was joined.

About a fortnight ago Mr. X. ran down for the day to visit his friend Y., who dwells somewhere on the south coast, within about one and a half hour’s journey from Croydon. Mr. X. having exposed sixteen quarter-plates, Y. enquired of him when they would be developed. “To-night,” answered X., and added, “Perhaps before I get to Croydon.” Y. expressed incredulity, on which X. guaranteed that he would have all the plates developed before reaching his destination.

No previous preparation had been made, and the train started in forty minutes from the time of above conversation. A sheet of ruby paper, some drawing pins, some oiled paper, and a piece of Willesden waterproof paper, together with Beach’s developer, in two solutions, were procured. The guard was duly “tipped,” and a pail of water obtained from the engine-driver. Mr. X. being safely locked in a third-class compartment, the Willesden paper was made into a tray, with sides three inches deep, on account of the swaying of the train. The ruby paper was pinned over the carriage lamp, and the blinds carefully drawn. The night was, fortunately, a dark one. Most of the plates were shutter views; these were first developed, the developer being used for about three plates and then thrown away. The time views were subsequently developed, with a suitable modification in the proportions of developer. The plates were well rinsed in the pail of water, and while wet wrapped in oiled paper, and thus packed in the ordinary boxes in which they are sold; the object of using oiled paper being that it does not stick to the film when the latter is either dry or wet. The plates were all developed before Red Hill was reached; the fixing being deferred until arriving home.

The resulting negatives were not noticeably inferior to those which the same worker generally produces in his dark-room. We have before us a print of a wreck with fisher-boats “salving,” which is distinctly above the average skilled amateur work.

If so good a result is attained by adapting a railway carriage on the spur of the moment, even better could be done by pre-arranging to make use of the dreary time spent in traveling by night. The above _tour de force_ is a strong argument in favor of those railway companies who run journeys of from five hours upwards, such as the Scotch express, providing a well-fitted but inexpensive dark-room. A luggage van might be converted, with an open compartment for workers to sit in when their “dark deeds” are done.
