This is an amazingly simple to use filter, yet yields some remarkable results!
The Rainy and Snowy effects look quite real!

Here I enlarged my source image to 200%, ran the filter for Rainy, and re-scaled the image by 50%.
The image was back to its original size and the I adjusted the opacity of the rain layer.
I love this filter!!

Stunning results! What a great filter..

Rain..

More rain.

Thanks a lot for your appreciation and experiments, Photomaster and Zero01.

Another interesting rain animation....
