Systems and methods for reducing the visibility of rain in acquired images are provided. One or more inputs relating the scene desired to be acquired by the user are used to retrieve camera settings that will reduce the visibility of rain in acquired images. Additionally, features relating to the scene may be automatically determined and used alone, or in combination with user inputs, to retrieve camera settings. The acquired images may be part of a video. Another feature of the invention is its use as a rain gauge. The camera settings are adjusted to enhance the visibility of rain, then one or more images are acquired and analyzed for the amount and size of raindrops.
