Between-the- Lens Shutter: However, although a long focal length lens is mandatory, it need not be expensive. The utmost of critical sharpness in a portrait lens is not necessary, or even desired, since considerable diffusion can be tolerated in portrait negatives. Your lens needn't be in a shutter for strictly studio portraits, either. A lens in barrel is perfectly satisfactory, since you can provide yourself with a simple Packard shutter to use behind the lens. Many portrait men actually prefer the Packard to the more costly between-the- lens shutterlens shutters.
In the beginning, you can't expect to crash into the coverage of spectacular attractions like major league baseball and the intersectional football classics, and the buyers of your pictures will not be newspapers or magazines. However, you should try to equip yourself to shoot pictures just as good as those in the magazine coverage of major sports events, because such pictures are what your own clients would really like to buy if they could get them.
Physical equipment for good sports pictures these days means electronic flash for indoor work and a focal plane shutter for outdoors. You can get by nicely with ordinary flash indoors and with an efficient between-the- lens shutterlens shutter outdoors, of course, but there is a definite advantage in being able to shoot at the fastest possible shutter speeds.
But in fact the picture was not a duplicate, for the viewing lens was at another point in space than the taking lens: by the phenomenon of parallax the images, particularly of subjects close to the camera, were slightly different. This discrepancy was corrected by the introduction of the single-lens reflex camera. The Mirror was now put inside the Camera body. By an ingenious spring-loaded mechanism it flipped from its 45 ° position to the horizontal on pressing the shutter release. The American Graflex (introduced in 1903) and the British Soho Reflex of three years later became the standard hand cameras of pictorial photographers for the first two decades of the century.
