Focus Magic——让模糊照片变清楚

如果一张照片构图、瞬间都不错，就是有一点点虚，难道这张照片就真的不可救药了吗？通过Photoshop有多种办法对拍虚的照片进行后期处理，只是比较麻烦。而通过Focus Magic的软件，可以轻松地让模糊的照片变清晰。（提醒：让模糊的照片变清晰是在一定程度内的补救措施，真正拍虚的照片无论如何也是不可能变清晰的。）     

包装设计中产品摄影的色调运用

包装是消费者率先接触的商品形象,商品包装设计在提高产品竞争力,建立品牌形象方面起着重要作用。在现代包装设计作品中,包装产品摄影因其一目了然、最清晰地表现商品,而使用越来越频繁。色彩在任何艺术中都是最直接、最感性、最具表现力的元素,它能够传递感情、表达情绪,对消费者产生强烈的视觉冲击力,是包装设计的重要视觉元素,是商品的语言,因此合理运用产品摄影的色调在包装设计中有着至关重要的作用。

这里有你需要的、关于摄影的一切建议。本期重点提示: 1、经过裁剪,可让照片更具视觉冲击力。2、f/22的小光圈确实能带来大景深,但由于光线的衍射也会降低影像品质。3、画面细节信息对于画面的叙述至关重要。4、构图时要有所取舍,突出主体,这样,画面会更透气。如果你希望听到关于自己作品的建设性意见,如果你希望获得在各个方面提高摄影水平的忠告——从构图到后期处理的细节,请与我们联系。

色温与电视摄像技术中的黑、白平衡调整

在影视摄像技术中，色温与黑、白平衡调整是两个很重要的术语，在摄像过程中，能够根据光源色温正确地选择色温滤色片和调整黑、白平衡，对于色彩再现有着重要的意义。     

The Preservation of Colour In Mounted Colour Prints

The main causes of dyes fading in photographic colour prints on paper or film are reviewed, and some suggestions to bear in mind while mounting colour prints, in order to reduce colour changes as far as possible, are described.     

Printing Colour Negatives

The problems encountered in making positive prints From negotives in colour photography are considered. An account is given of the various types of printer which have been devised in order to obtain a high yield of acceptable prints from negatives exposed by amateurs under widely varying conditions.     

The Land Demonstrations in relation to Colour Theory and Colour Photography

Colour effects observed in Land photographs suggest other well-known perceptual phenomena. An explanation of the Land colours must, however, be in terms of the basic mechanisms on which all these phenomena are dependent. Trichromatic theory postulates the nature of the initial stage in the colour reception process, but it has little applicability to the qualitative phenomena of colour vision. The opponents theory of Hering is here used as a basis for later stages in the visual process in order to explain qualitative phenomena in terms of neural mechanisms. Methods are described by means of which tristimulus specifications for the receptors can be selected which are appropriate to the trichromatic theory and to an opponents theory based on the trichromatic theory. The Land photographs can then be understood in terms of such a system, provided there occur changes in sensitivity of the receptors, or adaptive changes which simulate such changes in sensitivity at a later stage in the visual process. Such changes are partly dependent on interaction between outputs corresponding to a particular retinal area and those corresponding to a larger retinal area. These mechanisms are also discussed in relation to the suppressor mechanism for chromatic aberration. Colour photography is essentially satisfied by a trichromatic process as a photograph has, ideally, to produce similar activity at the first stage in the visual process as do the objects photographed. But in so far as modifications are necessary in a photograph to compensate for the limitations of photographic reproduction and the conditions in which the photograph is viewed, it may be useful to go beyond the trichromatic scheme both to understand the nature of such modifications and to simplify their implementation. The Land demonstrations are important as they highlight basic perceptual phenomena and provide a means of obtaining quantitative data which may reveal the nature of the underlying mechanisms.     

21st Hurter And Driffield Memorial Lecture Colour Science and Colour Photography

Frederic E. Ives was the first colour photographer to follow consistently the example of Hurter and Driffield, to seek scientific understanding of the photographic process, and to base his colour photographic methods on scientific knowledge. The theory of colour vision and colour photography worked out by Ives following the pioneering work of Maxwell is the basis of modern theories which explain the importance of accurate colour measurement and of the tolerances of the human eye in the practice of colour reproduction. The place of these theories in colour photography is discussed.     

Action of Red-sensitive Colour Mechanism on Blue-sensitive Colour Mechanism in Visual Masking

In the visual masking effect, metacontrast, the perceived brightness of a flash of light is reduced by the presentation of a second flash in an adjacent region of the visual field. A metacontrast masking interaction between different colour mechanisms is examined in the present study. The spectral compositions and intensities of the stimuli are chosen so that the first (test) flash preferentially stimulates the blue-sensitive colour mechanism and the second (masking) flash preferentially stimulates the red-sensitive colour mechanism. Elevation in test-flash threshold is measured as a function of delay in presentation of the masking flash and an interaction effect shown to occur at both positive and negative masking-flash delays.
