Dr. Bailey, of Monaghan, contributes both landscapes and portraits of very good quality. Mr. T. M. Brownrigg shows seventeen photographs all excellent examples of the wet collodion process. Many of them are exquisite bits of photography, and evince an amount of thought and care in selecting the best point of view, arranging the lines of the subject, and catching the best effect of light so as to make them pictures, which is seldom attended to by professional photographers.

Amongst the Irish professional photographers in landscape work, Mr. F. Mares, of Dublin, stands pre-eminent. His pictures of Killarney, and views in the county of Wicklow, are very beautiful, and give evidence of a cultivated eye and artistic taste in the selection of his subjects and points of view. There are other excellent views and architectural subjects by Irish photographers; but we are sorry to observe some that really ought not to have been admitted. They are not even average photography, being utterly destitute of manipulative skill, and as deficient in art-excellence as they can well be.

One branch of landscape, or, we should say, marine photography, is without competition. We refer to those exquisite and charming transparencies by Mr. C. S. Breese. His moonlight effect is wonderfully managed; the water looks “alive,” and the moonlight is dancing on the waves just as we have seen it far away upon the sea. His “Breaking Wave” is marvellous, coming to shore with its cavernous curl; we almost fancy we hear its angry howl as it dashes itself into foam on the beach. We have seen such a wave sweep the deck of a ship before now, and know well with what a ponderous weight and velocity it comes; and we wonder the more at Mr. Breese’s success in catching the wave in such a position. We cannot, however, speak so highly of the “Sunlight” effects by the same artist. The transparencies as photographs are inimitable; but there is colour introduced into the skies which ought to have been taken up by the rocks, and so carried into the foregrounds of the pictures, to be natural. Such warm skies and cold middle distances and foregrounds are too antagonistic for the harmony of nature.

In portraiture, our Irish brethren of the camera contribute somewhat liberally. In that branch we noticed the works of Messrs. Robertson and Co., S. Lawrence, and G. Schroeder, of Grafton Street; Millard and Robinson, Nelson and Marshall, and S. Chancellor, of Sackville Street, Dublin. T. Cranfield, Grafton Street, also exhibits some photographs beautifully coloured in oil.

The most eminent English photographers also show up well. We saw the well-known works of Mayall, Silvy, Claudet, Maull and Co., and others, eminent in plain photography. Messrs. Lock and Whitfield exhibit a Royal case of exquisitely coloured photographs of the Prince and Princess of Wales, and Prince Albert Victor. Mr. G. Wharton Simpson also exhibits a few specimens of his beautiful collodio-chloride of silver printing process. There are some lovely specimens of that process with such a frightfully ugly name, but which, in plain parlance, are pictures on opal glass, though Mr. Helsby has christened them “Helioaristotypia miniatures.” As a set-off to this, the next dry process that is discovered should be called “Hydrophobiatypia.”

In amateur portraiture, Mr. H. Cooper, Jun., exhibits a large number of his clever life studies, as well as those quiet and charming representations of his friends in their habits as they live.

Solar camera enlargements are very numerously contributed. Mr. Claudet sends some good pictures enlarged by solar camera, and developed with gallic acid. Mr. Salomon also has some very good examples of enlarging. Dr. D. Van Monckhoven is an exhibitor of the capabilities of his direct printing camera. Mr. Mayall exhibits two series of very interesting enlargements by the Monckhoven camera, printed direct on albumenized paper; one is Tennyson, in eight different sizes, from a one-ninth to a life-size head on a whole sheet of paper; of the other, Captain Grant, there are seven similar pictures. These photographs are all bold and vigorous and uniform in colour, and come nearer to our idea of what an enlargement should be than anything we have yet seen. Of the two, that of the Poet-Laureate is the best; the other is harsher, which is in all probability due to the difference in the subjects themselves. We can easily imagine that the face of Captain Grant, bronzed and weather-beaten as it must be, will present more obstacles to the obtaining of a soft negative than that of Tennyson. Specimens of photo-sculpture are also to be seen at the Dublin Exhibition, many of which are very pretty and life-like statuettes; but some of the figures seem much too large in the busts, and the plinths on which the figures of ladies stand are in very bad taste; being diminishing beads of a circular form, they suggest the idea of a huge crinoline just dropped.

Nearly all the denominations of photography have their representative forms and impressions in this Exhibition; and the history of the art, from the early days of the Daguerreotype to the latest vagary of the present day, may be traced in the collection of photographs spread before you on the walls and screens of the Dublin International Exhibition. There is the Daguerreotype, the Ambrotype, and the collodiotype, which ought to have been known as the Archertype; for the wet collodion process, although it is the most important of all the discoveries in photography that have been made since the first pictures were obtained by Wedgwood, is without a name conferring honour on the man who first applied collodion to photography. Archer’s name is generally associated with it, but without taking that definite and appellative form it ought to. We know that another claimant has been “cutting in” for the honour, but unless that claim can be “backed up” by data, we are not disposed to believe that it was anterior to 1851—the year of the first exhibition; at that date we know that Mr. Archer took photographs on collodionized glass plates. Then why should we not honour Archer as the French honoured Daguerre, and call the wet collodion process the Archertype?

In printing and toning, there are samples of nearly all the formulæ that have been discovered since the days of printing on plain salted paper and fixing in “hypo” only. There are prints on plain paper and on albumenized paper, toned and fixed in every conceivable way. There are prints on glass, porcelain, and ivory; prints in carbon, from the negative direct; and impressions in printer’s ink from plates, blocks, and lithographic stones, which have had the subjects transferred to them by the aid of photography. There are Wothlytypes, and Simpsontypes, and Tooveytypes, and all the other types that have sprung from a desire to introduce novelties into the art.

In graphs and the various forms and fanciful applications of photography to portraiture, &c., there are stereographs and micrographs, and the old-fashioned “sit-on-a-chair” graphs, the “stand-not-at-ease” graphs, the “small carte” graph, the “large carte” graph, the “casket gem” graph, the “magnesium” graph, the “cameo” graph, the “double-stupid” graph, and the latest of all novelties, the “turn-me-round” graph. The latter is a great curiosity, and must have been suggested by a recollection of that “scientific toy” of ancient manufacture with which we used to awaken the wonder of our little brothers and sisters at Christmas parties when we were boys, by twirling before their astonished eyes a piece of cardboard with a bird painted on one side and a cage on the other, both pictures being seen at the same time during the rapid revolution of the card.
