摘要:
A color image forming method is disclosed, comprising applying additive color mixing to a subtractive color mixture to perform color correction. Specifically, a fluorescent substance exhibiting emission in the visible light wavelength region, which is used for the additive color mixing, is mixed with a compound having an absorption in the visible light wavelength region.
摘要:
A method for exposing a light-sensitive photographic material comprising at least two spectrally different but partly overapping light-sensitive phases which is advantageous for obtaining a color photographic image with color purity, said method comprising a step of exposing said photographic material to light through a filter which absorbs at least a part of said spectrally overapped region.
摘要:
The invention relates to a method and apparatus for exposing a photosensitive material such as colour negative film, colour reversal film and colour photographic paper, for evaluating the photographic characteristics of said photosensitive material. At least two different areas of the material are exposed differently and at least one light beam is used. At least one light beam is split into at least first and second parts which are equal to each other. At least two different areas are respectively exposed to the first part of the said light beam and the second part of the said light beam.

摘要:
A process for the production of a multicolour reversal image with improved colour balance is provided which process comprises the steps of directing incident image light dot- or linewise modulated by a light-distributing means onto a multicolour photographic silver halide emulsion material containing a blue-, a green- and a red-sensitive silver halide emulsion layer and processing said siiver halide emulsion layers to form a colour reversal image. In the maximum density part of the dots or lines of said light distributing means e.g. a contact screen the ratio of the absorption density (D) for the light corresponding with the spectral sensitivity region of the silver halide emulsion layer being during the exposure (E) most remote from the light-distributing means to the absorption density for the light of the whole visible spectrum (400 - 700 nm) is higher than the said ratio in any other density part of the dots or lines (see Figure 1).
