Now I am thinking of it, indeed retrocity, everything noise, pixel (especially the one with 'Mezzo' in its name) is very much needed when creating 'randomness' as well. Especially when start with the clouds rendering. The Third Party filter I use the most (meanwhile note that I do not use a lot of filters that change the whole image into something else) is actually a free one: Retroscan which is made by Deep Devices. A very nice thing if you want your images to appear as tv-footage.
