Otherwise, vignetting may occur when zooming out.

否则，可能会出现渐晕放大了。

Vignetting refers to the lightening or darkening of the edges of an image.

虚光照是指增亮或是调暗图片的边缘。

Meanwhile a new method to compute the vignetting coefficients has been given.

文章同时给出了计算渐晕系数的新方法。

Custom presets are then applied that add contrast, vignetting, and sharpening.

然后将利用自定义的预设文件处理对比度、修饰和锐度等。

Vignetting and distortion are both corrected excellently for a lens of this speed.

渐晕和变形都纠正了这种速度镜头出色。

It is only to be used at the longest telephoto setting of the camera in order to avoid vignetting.

只有将在最长的长焦相机的设置使用，以避免晕。

Clicking on this button will recompute the vignetting factors for each field based upon the current lens data.

点击这个按键将根据当前镜头数据重新计算每个视场的渐晕因子。

Example of Vignetting. Notice how the screen corners get darker and more blurred and also show color separation.

渐晕特效例子。注意屏幕的边角区域是如何变暗、模糊和颜色分离的。

To do this, a blue overlay was added and some vignetting around the edges which allowed the interior lights to really pop.

为了实现这个目标，我叠加了蓝色，并将照片颜色调暗，这样室内的光线就很显眼。

I also added some vignetting (shadow around the edges of the image) to help draw the eye to the center of the composition.

我也添加了一些小插图(图边缘周围的阴影)来帮助将注意力转移到图的中心区域。

Vignetting is created either in camera using vignetting hoods or in darkroom by burning or dodging the edges of the image.

虚光照可以通过虚光罩创造出来，或是在暗室里通过烘烤或挡光图片的边缘。

5 cameras, 5 sets of vintage vignetting, film scratch, black and white &cross processing effects for that off-the-hip analog look.

The established model can rejuvenate the input image so as to finally resist vignetting from degradation of camera pattern in a cell phone.

然后根据该暗角模型对输入图像进行复原，最终达到修正手机摄像模组暗角退化的目的。

The post production was very important to increase the visual impact. The colours are very saturated and I added a vignetting to create a dramatic effect.

后期合成对于提高视觉效果非常重要。色彩都非常的饱和，我添加了一点光晕来创建一种梦幻的效果。

A method is introduced for testing stray light coefficient, vignetting coefficient and image surface uniformity optical system with large aperture and long focal length.
