1.This paper offers a brief and concise introduction on some Kodak multispeed photographic films newly presented on the market in recent years, namely: PJM (exposure latitude lSO 100-1000),Gold Max (exposure latitude ISO 50-3 200). Some relevant photographic characteristics and sensitometric curves are cited.
2.It was shown that ANS and ANE have considerable photosensitivity 15.50mj/cm2,6.94mj/cm2 respectively. UVspectra of ANS snd ANE have shown an absorption ofλ max at 334nm、 334.4nm respectively.
3.The paper quoted datas showing in details the influence of the thickness of the emulsion sob-layer and its AgX grains size on the speed of the front emulsion layer.
4.Meter the scene, select an f-stop, set the autoflash aperture to the same f-stop, and shoot.
5.Xerographic quantum efficiency and sensitivity for positive charging increased with CGM concentration,while that for negative charging decreased with CGM concentration.
6.When gold, sulfur and sodium sulfite were employed to serve as chemical sensitizers, a suitable technique must be adopted. Under the same conditions of exposure and development, the sensitivity increased from S=16 DIN to S=25 DIN.
7.It was shown that ANS and ANE have considerable photosensitivities. They are 15.50mj/cm2, 6.94mj/cm2 respectively. UV spectrums of ANS and ANE shown an absorption of λmax at 334nm 334,4nm respectively.
