Color matching skills in post-production of film and television

1. Adjust according to the brightness of the picture.

If in film and television production, the shot picture is too bright and gray, lacking in saturation, and there are obvious gaps in the black part. For example, the picture should be black, such as hair, eyes and other colors are not black enough, and the picture may not be bright enough, so it is relatively appropriate to adjust with the curve in AE, which is equivalent to the gamma curve of image exposure. Does the gamma curve of the film appear long? s？ The shape, his gray feeling is very vivid. In order to make the lens of TV camera as close as possible to the film effect, it is necessary to adjust the curve. It has about 14 control points to adjust the curve, and these are the reasons why the curve can control the picture more accurately. Of course, three o'clock is enough here.

By adjusting the curve, the black part is added, so that the image should be black? News? Go down, which one should I go to? Mention? Get up, so that the tone is balanced and the whole picture is obviously vivid.

Another method is to use the overlay mode of the layer to adjust, copy the material in AE, and set the overlay mode of the upper layer to soft light. At this time, you will find that all colors are saturated and the dark parts are aggravated. This painting carries a lot of weight. Then, blur this layer a little, and the whole picture becomes softer, and the particle noise is also weakened a lot. If the picture itself is already dark, then set the overlay mode to the screen. Then adjust the brightness and blur, of course, the color should not be oversaturated. It is best to color the display, often output the color matching results to the TV, and observe the difference between the computer and the TV (preferably dynamic, so as to compare the signal-to-noise ratio).

2. Adjust according to color components

IV 122524 color composition adjustment is to select a scene with bright colors for adjustment. For example, a picture of a street should show a gray-green tone. At this time, you should choose the lens with bright red or yellow eyes, and adjust it first with the above method. If it is not enough, purify red or yellow in hue/saturation respectively, and pull the ruler to the right. If the value is large, the result will be noise in solid color, and finally only the original layer can be copied. Photometric superposition method is used, so that the color of the lower layer will affect the upper layer, but at the same time its granularity remains unchanged, so that when the lower layer is blurred, the original granularity can be basically maintained and the purity of the color can be improved. When adjusting, it is necessary to carefully circle the areas with slight color difference in hue/saturation, adjust the color system one by one to distinguish them, and then deal with them uniformly.
