Having all our materials at hand, let us set to work. The stretcher has been bought to suit the size of the photograph, but probably the latter will have to be cut a little round the edges, to make it just about an eighth of an inch smaller than the former. Take some of the prepared canvas, and cut it an inch and a half larger than the photo; wet it thoroughly, and fasten it to a board with drawing-pins, the prepared side uppermost. The back of the photo will require to be rubbed with glass-paper, if it is a thick one; not otherwise, for fear of making holes in it. To manage this carefully is important.

A sheet of clean paper should be laid on a drawing-board, and the photo placed on it face downwards, and firmly secured with drawing-pins. Now rub it gently with the glass-paper, until the picture is rendered semi-transparent. Then take it from the board, and give it a bath in the solution. Lay it in a dish, and cover it entirely with the solution, letting it remain there for a few minutes; lift it out, and again lay it on the board face downwards, and with a small sponge dab off any superfluity of liquid. Pour that which is left in the dish back into the bottle.

The bottle of canvasine adhesive is next needed. With a brush well filled with it, lay a thick coating all over the back of the photo as evenly as possible, then take up the picture, and place it in exact position on the canvas which is stretched on the board, and now the face must be uppermost. Notice particularly that the photo lies straight with the threads of canvas; if it is crookedly placed it cannot be expected to look well; the perpendicular and horizontal threads should run perfectly level with the top and bottom and sides of the picture. Press down the photo with the hand, and then slightly roll it out.

Take another piece of canvas of the same size as the first: this has now to be pressed thoroughly, the roller being passed in every direction over the surface. Continue rolling it for five minutes or more, so that the canvas lines become indented in the paper and are distinctly visible. Watch it constantly during the process, and if it does not adhere quite firmly to the stretched canvas, put a little more adhesive solution round the edges, and pass the presser quickly up and down over the photo, still with the spare canvas between, to rid it of all air-bubbles; then repeat the rolling.

Not until every part of the photo adheres, and all the canvas lines are clearly marked, must the process of rolling be discontinued. After this, the photo must be allowed to dry gradually, still stretched on the board. No painting must be attempted until it is quite dry, which it will be in about three hours. Some prefer to paint it when it is so far prepared, and afterwards to fix it on the stretcher; others consider the better plan is to fix it first on the wooden stretcher and then to paint it; but this is a matter of choice, and workers may follow either plan with equal chances of success.

To stretch it, we must proceed in the following manner. Lay the canvas evenly on the frame and nail it over the back; when all four sides are thus secured, take the wedges, and hammer them into the holes made purposely for them until the canvas is sufficiently stretched. Be careful to place the board in a good light for painting; it takes much longer to do, and cannot be done half as well either, if the worker sits so that the shadow of her hand falls on the picture. A piece of clean writing-paper to place at times under the hand to prevent finger-marks may be found useful.

Now for the painting. We will begin with the face. In colouring photographs, the paints have to be constantly washed off, and it is a well-known fact that nothing does this so well as the tongue, because it acts on the photo so as to remove all grease better than anything else will: but some people will perhaps be somewhat afraid thus to wet the surface, on account of the nature of the paints. The tongue may, however, be used at any rate for the flesh parts, and a small wet sponge can be employed for the rest of the picture. Wet the complexion over with the tongue, then wash in the shadows with some flesh shadow mixture, to which a little canvasine medium and water have been added, and wipe it off again at once. Pay attention to the shadows that they are of the right tints: for fair children they will be of a slightly blue hue; for dark complexions a little wood brown must be added to the shadow colour. Now lay over the complexion a wash of flesh-tint No. 1, and wipe it off again directly; repeat the wash as often as necessary until a good colour is obtained. Sometimes as many as six applications are needed; the great point is to get a good even layer of colour. In rendering dark complexions, a trifle of wood brown may be added to flesh No. 2, and this will give the requisite depth of colour. Put in the warm complexion-tints with flesh No. 2. Place a drop of it, modified with No. 1, over the whole cheek, and wipe it off again immediately. Repeat until the right strength of colour is secured; deepen the tint as it nears the centre of the cheek, so as to preserve the rounded appearance that is one of the greatest charms that youth and beauty possess. Strengthen the shadows under eyes and eyebrows, round the nostrils, and on the chin.

Mixtures of blue and brown, and of green and brown, serve for the demi-tints which soften the deep shadows by gentle gradations into the local colouring. The tints may be effectually blended into one another by an occasional wash of flesh No. 1 being carried over the whole.

Between each operation the colour must be dabbed off as soon as it has had time to sink into the photograph; it must not in any case be allowed to rest long, or the wash will dry spotty, and when that happens it is exceedingly difficult to remedy. The draperies are washed in before the details of the face are begun, as when the latter are painted the colours must not be wiped off afterwards; they are not treated in the same way as the washes, but more as finishing-touches.

Draperies and backgrounds are laid in with a full brush in broad washes, the photograph being first damped slightly with canvasine medium; the colours are laid on freely with decisive strokes, and sponged off, the washes being continued until the tint is dark enough. Skies may be represented with blue tinged with green, and when dry, some light clouds may be dabbled in with Chinese white.
