The surface elements of the cufflinks are very delicate

Tone contrast is determined by the cuff of the scene itself, the colors and lighting conditions. Optics (such as filters, lenses yarn), photosensitive materials, control of exposure and film processing conditions of the selection to be controlled. Contrast, also known as the "contrast between light and dark." cufflinkshave become the interpretation of the great attention to the surface of the decorative effect. The scene or images of light and shade difference. Scene contrast is a photo features maximum brightness and minimum brightness than the right value. The image contrast is the difference of a maximum density and minimum density of the image: the image contrast and scene contrast ratio of gamma to use the Greek letter gamma, which marks the extent of film developing. Contrast scene seems clear, on the contrary appear dull: contrast of images is called a hard tone, otherwise known as a soft tone.
Contrast the scene in the standard wash conditions, the image contrast. Photography, it is necessary to strictly control the scene contrast, so as not to exceed the tolerance of the film characteristic curve, resulting in images of bright or dark the level of loss. In fact, designers of the cufflinks in the conceptual stage firstly consider the plane effect. Chiaroscuro scene of cufflinks color and reflective rate the performance of the scene brightness interval or brightness contrast. Shading configuration subject to the object itself and the proper allocation of the bright and dark in the picture space. Shading configuration can form a different tone contrast and screen structure. For example, a small piece of bright tone, or a small piece of a large area of bright tone Shadow adjust, it will attract the audience's attention in a large area in the shadow tone.
 The movie screen shape appropriate to the use of light and shade configuration, highlighting the main also help deal with the composition of the picture, showing the spatial extent. Shading configuration also constitutes one of the factors at the equilibrium of the screen. For example, the picture side is very strong shadows, the other side is very light the next tune, it will cause the trapped surface appears to tilt. Secondary is to think one modeling of the cufflinksthat can be attached to these decorations. Appropriate adjustments to brightness relationship allows the screen to maintain stable and balanced; and Philippine requirements on both sides of the screen entirely consistent tone, but to constitute a balanced picture effect at the same time due attention to the brightness changes, so that the picture has a rich tone level.
It is to obtain images of the optical performance by means of optical lenses and a variety of optical accessories photography modeling. Indispensable technical conditions, but also one of the basic means of cinematography shape. Therefore, the surface elements of the cufflinks are very delicate. When shooting using different focal length lens, the light holes of different sizes, changing the focus, and optical accessories such as filters, half-length mirror, magnification mirror, the effect microscopy, are likely to change or improve the image state. For example, the use of different focal length lens available to the perspective of the different lines and different range of the actual situation, effects of changes as well as vertical and horizontal velocity.
Zoom lens focal length, get moving picture effect, the audience at the same time or gradually see the scene in the picture, resulting in a different visual impression, another example, use the filter to adjust the hue and contrast, to achieve a specific tone effect. Creative photography, mastered the use of optical performance means to enrich the form of photographic modeling, and enhance the image of the performance of the power and beauty sense. The light color performance means light and cufflinks color photography modeling. There is room left for the viewer for pondering over the cufflinks. Photography modeling the basic means of expression. The formation of tone, tone, tone, atmosphere, rendering, and Characterization of figures or shapes the expression of time and sense of space, performance, and are inseparable from the use of light and color.
