Contrast Photography — How to Master High Contrast Images
WebContrast analysis is a relatively simple but effective statistical method for testing theoretical predictions about differences between group means ag ainst the empirical data. Despite its advantages, contrast analysis is hardly used to date, perhaps be cause it is not implemented in a convenient manner in many statistical software packages. The high-frequency cut-off represents the optical limitations of the visual system's ability to resolve detail and is typically about 60 cycles per degree. The high-frequency cut-off is related to the packing density of the retinal photoreceptor cells : a finer matrix can resolve finer gratings. See more Contrast is the contradiction in luminance or colour that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the See more Contrast sensitivity is a measure of the ability to discern between luminances of different levels in a static image.
