PACE 304 HOME MOVIES FOR AUGUST EASIER TO ADJUST IN HEIGHT information nun CHALLENGER Reg. U. S. Pat. Off. SCREEN TPoei NOT ^kan^a ihe When you adjust the Da-Lite Challenger Screen to the desired viewing position, you do not need to make additional adjustments of the case or fabric to keep the picture area the right size. Raising the Challenger does not pull the fabric further from the case and thus necessitate moving the case up separately. Da-Lite's exclusive patented inner-locking device raises or lowers the case and the fully opened screen in one operation. • NO SEPARATE ADJUSTMENTS OF CASE • NO THUMBSCREWS TO TIGHTEN Ask your dealer for the Da-Lite Challenger Screen, Write for literature!

Q. / have a Imm. cam era and the pictures I take with it seem to be out of focus on the left side. I have taken the camera personally to the factory for inspection and while the technical department admits that something is wrong, still they insist — after examining my camera — that both camera and lens are in perfect condition. I've made tests, too, projecting my film with several makes of 8mm. projectors and in each instance the film projects with the left side of the picture out of focus. What do you think causes this trouble} A. The only test you apparently have not made is to try filming with another lens in your camera. Go to your dealer or to the factory and ask them to fit another lens to your camera — loan it to you just long enough to shoot another roll of film. If the resultant roll is also out of focus, then you may be quite sure there is something wrong mechanically with your camera — probably in the channel of the film gate which does not allow the film to lie flat against the aperture. If the film comes up sharply focused, you'll know the fault lies with your present camera lens. Safety Guaranteed (Harry Milliard, Pueblo, Colo.) Q. / would like to submit for review a film I made recently but I'm a little ' timid about risking it in the mails. You see, I wouldn't want to lose it or have it become damaged in any way. What is the best method for shipment? A. If you'll mark your reel and container plainly with your name and address, then ship it to us via insured Parcel Post or Railway Express, it will arrive safely. All films sent the editors for review are returned by Railway Express and are adequately insured. To date, no films sent in for review have ever gone astray during transit. Dolly Shot (Barry Horton, Dallas, Tex.) Q. In shooting a dolly or trucking shot — that is, moving in closer to subject with camera while shooting — isn't it also necessary to gradually change focus of lens at the same time? A. This would depend upon the aperture at which you were shooting. If you were using a small lens stop, depth of focus would be extreme, at least sufficient to keep subject in sharp focus • Readers: This department is for your benefit.

Under adverse light conditions or indoors with insufficient artificial light necessitating shooting at f/3.5 or less, it might be necessary to adjust focus of lens as you approach subject with camera in the dolly action. Frame Size (Alfred Tucker, Hillside, N. J.) Q. // an Smm. and a i6mm camera were set up side by side at a given distance from a scene or object, would they both register the same proportion of the scene? A. Yes, assuming the i6mm. camera is fitted with a i inch lens and the 8mm. camera with the usual Yz inch lens. Haze Filters (O. J. Seifert, M. D., New Ulm, Minn.) Q. / own a 16mm. Eastman camera. In making sunset shots, kindly advise if a haze filter should be used and also what lens opening. Also, if haze filter should be used in close-ups or just long shots. A. Purpose of haze filter is to enable lens to penetrate haze in distant scenes and thus obtain definition in distant objects such as mountains, etc. There would be no advantage in using it for sunset shots. Nor is there any benefit obtained in using a haze filter in medium or close-up shots. Best sunset shots are obtained with lens stopped down to enhance silhouette effect of cloud formations. Blue Photofloods (M. H. Roberts, Portland,) Ore. Q. What is the Weston rating for regular Kodachrome when used with G. E. daylight blue Photofloods? I have four rolls of 8 mm. regular Kodachrome on which expiration dates are drawing near. In order to use up this film before expiration, I'm obliged to film indoors. The use of daylight blue Photofloods seems to be the only solution. However, I have failed to find anything but opinions on the correct meter reading to use.
