Well, here's a little attempt by me.  I just did a test image previously last January, and like the clouds all the same.  Hardly like the photographs, plus I'm just playing around with sky atmosphere.  That's what probably got me hooked to get version 6 for the spectral atmospheres alone.  But prior to what the poster mentioned, it does look too soft or too grainy particularly the dark edges and contrast.  I used Vue 6 Easel for that test image.

Now, I have Esprit version 6 and playing around with metaclouds and the spectral atmosphere.  I love the kind of realism (make believe for now) you can use for instance -- Ambient Occlusion, Global Illumination, and Global Radiosity -- so glad I made it to the next level.

I guess out of suggestion, in order to get that whispy, puffy feel, don't forget that you can turn up Quality Boost for both the Sky and Haze (including up-ing the Scattering Anisotropy) and Light in the Atmosphere panel.  I figured that out when I tried Terragen 2.  I just adjust the camera in millimeters (35mm) to get the realistic feel.  It can take a lot of doing, but taken into consideration, it would be a while until we can see cumulus clouds like in the photos - if such an achievement is made.

Just thought I give my 2 cents here.
