AND) PHOTOGRAPHIC effectiveness. I[t is to the State that the popular mind should turn, demanding a diffusion of knowledge which will enable the strong man and woman to keep healthy, to the greater benelit of the individual and the greater safety of the majority. This ignorance deprives thousands annuallly of that physical energy upon which the commercial and moral standards of the nation materially depend. Yours faithfully, H.M.” Replies to Correspondents, C.).—), Write J. D. Crriflin, Floodgate Street, for the glass you reqire. 2, Weshall deal with the Vapour Lamp i in our November issue. 3, No. L.G.—Writes: Windly give me information through your correspondence columns, L have several fine slides of ——— which I should like copies off. How can I set about it, to get best results. J reply:—We hesitated if it would not be best to send on your query to the firm named, and let them deal with the matter. It would be flagrant piracy, and we trust you will not demean your self by so cotemptible a proceeding as copying the slides mentioned. Your other query was answered hy post. Cnematographist in difficulties, writes :—1, I want to take an animated picture of vocalist singing ‘“ Holy City? with various effects, [ want a dissolving effect, on a constant background. in the left-hand top corer of picture, the effect scenes are all monotone cloths on rollers, I have five special scenes. Can you give me any idea of the method of working, so as to get the dissolying effects on to these scenes, 2, Can you tell me the method of producing the reversing effec ts on films. /y reply :—1, Set your scene with your singer in position, stirt singing, and the camera going at ‘the same time, when you get to the part of the song where the effect comes in, stop camera and singer, place the background cloth in the corner you wish with the figure suspended or otherwise, when all is ready let the singer take a few bars back, ‘and when she comes to the part where the effect of angels appear, start the machine and continue till effect vanishes then stop, remove the effect, then go on till the finish, stopping the machine at each effect, begiuning and finishing, and at the changing of each scene. But why go to the expense and trouble of taking films yourself, when there are so many experts who devote all their time and energies to this class of work, write to our advertisers and get a quotation from them, giving your ideas. 2, Get tivo films of the subject you want to reverse, and connect to the end of each, taking care that you turn the film towards the condensor in one and towards the lens in the other. A.G.—B. writes :—Until last season I was able to fully cope with all engagements myself, then [ got more than L could well yet “through myself, so engayed an assistant at so much per exhibition. On going “round to make up my dates, [lind my assistant of last season has forestalled me and has booked up for himself a number of engagements which always fell to me, what legal claim have I upon him, there was no avrecnient, but I fully expected he would have acted honestly with me. Answer :—Weare afraid A.G. las no rewedy, we have got the same trouble and can only put it down in the ledger, as payinent for experience, taking care in future to vet an agreement properly drawn up and signed, setting forth that all future es.gagements accruing from these sources shall bear commission.
