The photo was actually taken on a digital camera, then degraded using a few filters and some quick color changes to give it a vintage look.

其实它是用数码相机拍摄的，使用了一些滤镜和颜色调整，赋予其怀旧效果。

Satisfied results usually can not be got when processing color images degraded by fog and mist with the conventional enhancement algorithms such as histogram equalization and homomorphic filtering.

对于薄尘雾退化的彩色图像，用直方图均衡和同态滤波等常规增强算法处理往往不能得到满意的效果。
