METHOD OF WORKING.
First decide as to the colours or tints of the various parts ; then proceed to colour the larger patches, and afterwards put in the smaller detail. The colouring having to be of an impressionistic character, it is best for the beginner to apply it to the glass side of the slide ; this being a little dis tance away from the plane of focus, will prevent its being sharply rendered when projected on the screen, and will there fore allow of its being more roughly done than it otherwise would need to be. Take a little of the necessary colour, and add sufficient megilp to cause it to run easily, and mix with the finger tip ; smear a little over the centre only of the patch to be treated, and proceed to tap lightly upon it with the tip of the finger. The first application of the paint must be rather thick, so that when tapped upon with the finger it may be spread out into an even tint, and at the same time thin the colour to the right depth. The chief difficulty
to be overcome will be that of obtaining a tint perfectly even. Probably, the first attempts will result in a patchy effect, but the tapping must be continued until this disappears. When spread fairly evenly, select all those portions where the colour appears too deep, and tap them lightly again, so as to spread the colour into the sur roundings. If this in turn be comes too deep, dab off again until carried to the margins. In some cases it. may even be neces sary to wipe off some of the colour with a soft rag, and then spread the remainder, but it is always better to put as near as possible the right amount on the glass to com mence with. This can be judged very ac curately after a little experience.
