Ahem...as I was telling you before, I'm going to have to disappear for a bit. However, the term 'photorealistic clouds' could also be taken several ways. Perhaps you'd be so good as to post an image as an example of the kind of clouds you're looking to achieve so as to prevent me posting every cloud technique limited to two stock filters in my repertoire? I really don't think I'd even have time to type them all up... At any rate, post soon and I'll reply tonight if it's in the cards...otherwise, I'll have to reply sometime next week. Cheers! :-)
