A sitter enters--a lady, young, good-looking, and handsomely dressed, to meet another young, good-looking lady just going out. Fashion rules both fair subjects much in the same way as regards costume; a change of colour perhaps, but cut in much the same tyrannical style. The colour may make a slight difference in the two photographs, yet not sufficient to redeem the artist, who has only light and shadow to work with, if he cannot strike out something in the posing and accessories to individualise the different subjects or sitters. But the photographic artist, perhaps, has had six or seven young ladies, similarly dressed, one after another, during that forenoon, each sitter with her own ideas how she ought to be taken--ideas gleaned from someone else's pose, or something she has seen in a shop window or an album--ideas which the original instincts of the artist rebel against. The same may be said of the portrait painter, only that he has days, sometimes weeks, to study his subject, whereas the photographer is only allowed moments to collect his well-nigh scattered faculties. Again, the painter has variety of colour with which to cover over a repetition of design; but with black and white, a repetition will be at once discovered. This I mention as one only of many difficulties besetting the studio of a photographic artist from the moment the sitter enters, which renders his task all the more harassing, and which cannot trouble the layer-on of colours. A true photographer seems to me to rank with, and resemble, the troubadours of the middle ages, poets who poured out their impromptu verses to the call of the audience. He ought to be a reader of faces--a close scrutiniser of the inner workings of the subject before him; catch with an eagle glance the peculiarities of gait, the tricks of motion; and be gifted with the rare discrimination which can separate the natural habits from the society affectations. I think a photographer ought never to be in the studio when the sitter first enters. He or she ought to be left a little time alone, or rather, a special chamber ought to be set apart where the sitter may enter, with artistic objects to attract the attention placed about the room, while the artist, for a few moments, from an unseen point, may watch and study his subjects when they think themselves unobserved; afterwards let an employé enter and address the sitter while the photographer still watches from his point of observation, by which means he may judge and learn what is the difference between the sitter when alone and when in society. And so he may wait, after the instantaneous plate is in the camera, for the moment when the sitter unconsciously looks natural, to flash the light upon her or him; indeed, I have thought if the studios could be so constructed that the operator need never enter the room at all, but have the camera so adjusted from an outside room that the sitters might not know the
