paper presents a simple method for comparing the static resolving power of photographic film and CCD.

Effects of finger marks on image quality of storage digital laser films;

Major factors affecting the spectral sensitization efficiency of red-sensitizing dye for making laser film are discussed in this paper on the basis of some series of experimental data and years' practical experience.

Calibration of response curves for X-ray film;

Objective To investigate digital processing and clinical evaluation of compression ratios using JPEG2000 algorithm on traditional X-ray film.

More and more hospitals are using rapid processing technology for medical X-ray film.

Study on production of dioctyl terephthalate from waste sensitive film;

A method using Fe~(3+)-EDTA-Na_2S_2O_3 system as leaching agent for recovering silver from waste photosensitive film was studied and the optimum process conditions were examined.
