In a picture of the ‘Tercentenary Students’ Torchlight Procession of Edinburgh, 1884,’ I intentionally made the horses and portions of the crowd unduly large, on the same principle as the exaggeration of the fly.
My reasons for doing so were just and strictly according to the reality of a momentary effect; I state my reasons in order to show you that I was right in doing so, and also because I dare say this may be one of the objections to my treatment of this particular subject. I take up the position of a spectator whose pupils have been dilated by the semi-darkness, and who, with imagination active, is suddenly startled by the flaring and irregular flashing of the waving torches; shadows dart up to colossal proportions, also prominent objects, such as the mounted police, and it is only by means of this distortion of size that I have been able to give motion to the crowd, along with the weirdness of such an effect.
I would ask all who have seen a torchlight procession to recall the sensation, as closely as they can, when the first burst of torchlight came upon them, for that is the moment I have attempted to fix upon my canvas; and those who have not seen a large crowd under these conditions may imagine what it would be like by the aid of fire or torchlights which they have seen at other times. I would ask you to exercise the faculties of memory or imagination while I give you a brief description of the emotions it roused in my mind as one of the many thousand spectators, and the effect it had upon my seeing faculties, which will enable you to comprehend my motives for working as I did, preferring the strict reality of the instantaneous phase or impression to the actuality of the known form. (This I give you, not as an apology or explanation for my picture, but as the nearest illustration I can think about, at present, of one of the phenomenal laws of lighting.)
We were standing upon a house roof, looking over the city. Right and left lay Princes Street, with the Mound at our feet, and Scott’s Monument in the middle distance.
Most of the time we were in darkness, with the exception of one or two straggling candles at windows here and there, at wide intervals. A mellow glow at the south end of the North Bridge, a blue light behind the Monument, an occasional rocket fizzing from Calton Hill, also faintly illumined with white and blue fire, into the umber-tinted darkness of that starless, cloud-bulging sky, and the alternating glaring from Hanover Street of rose-coloured, white, and green lights, which dyed the upturned faces of the crowd and the columns of the Institution in a broad line with the scarlet or emerald colour of the fire then burning, for a few pulsating moments of eye-nerve-straining.
Then fell a deeper wave of darkness as the light passed from us, rushing over the heaving masses below, whence rose up that sympathetic thrilling sound which ever grips and holds the hearts of a crowd like one heart, and over the houses, with their lights dashed out for a moment by the passing away of that more intense light, all preparing me for the fantastic sight we were awaiting.
Then increased the murmuring louder in its hoarseness with the sound of many feet trampling, and as we looked towards the North Bridge, where the lamp-lights showed faintly, the yellow glare of the advancing torches gilded the sides of the opposite shops, while the houses on this side became more jetty in their intervening blackness, and in another moment they were blazing over the parapet of the bridge with a motion like the walking of a centipede of fire; and so on, with the slow appearance which distance always gives to all rapid motion, the procession crossed the bridge, hiding behind the shops and houses between the bridge and Princes Street, reappearing again by the Post Office, gliding along to Calton Hill; then they paused for a moment, turned round and came towards us, foreshortened, but growing vaster as they neared, until, with a sudden burst, they were rolling along beneath us, a heaving mass of upturned faces, crimson-tinted, with a river of yellow light rolling along the centre, white flames with orange terminations and wreaths of blurring rose and purple smoke, coats reversed, shirt sleeves or bare arms waving about the torch-sticks, smut-grimed faces, more like sweeps than students, with here and there a colossal blue-vestured guardian angel of order bestriding an exaggerated horse.
This is how it appeared to me and how I treated my picture—as I conceived it ought to be treated; not as I knew the men and horses to be, men and horses, but like the perturbed legions of spectres they for the moment became: ghosts of giants and dwarfs, and other strange forms, like those extinct monsters of the past, all whirling madly past me, a vision of passion and flame crossing a chaos of darkness; an invasion of demons, unreal, yet fascinating—a nightmare of glittering phantasmagoria of light and shadow, blending colour with intense blackness.
In this illustration I have given you the two most direct specimens of lighting a picture that I can think of; in the one portion you have the light coming from behind and making the objects stand out dark, as in sunrises, sunsets, moonlights, or artificial lights behind figures; in the other portion you have the light thrown into the picture, as from the spectator, or in open daylight, sunshine, or lamp-light effects, when the light is in front, and shadows fall behind or from the side.
I have divided both effects, as equally as they can be divided, into light and shadow, the light occupying an equal space with the dark. These are by no means the most satisfactory methods of dividing a picture, as they are apt to be mannered and fixed; what I would rather advise is, to allow either shadow or light to predominate—shadow, if force is required; light, if air and delicacy are the aims you wish to strive for. Yet, as they contain within them the primal divisions of all lighting, they are the most appropriate for my present purpose.
