I just got the Lightsphere II Cloud, used this past weekend on a cruise that a buddy and I went on. Wish I could share the pics, but he has a thing about internet privacy.
But let me tell you, it really works! The first shots had harsh specular highlights. When I put the Lightsphere on, they vanished. I can't wait to try it out some more.
What I can say is that the examples that Gary Fong shows on the website (like the model shoot) are what you can expect in real life so far. I can see the benefit of Jessica's comments about possibly needing both the Cloud and the Clear Lightspheres.
What I can share is a pic that I did with the Nikon 10.5 fish-eye of our cabin. (See attached photo) I am assuming that there would have been a bit higher contrast with the Clear in this sample.
The other thing to note is that the bounce cards that have been mentioned, direct the light - while the Lightsphere primarily bounces light in a 360 degree direction. As one can see in my sample image, this picked up on the heavy use of orange that Carnival uses at least on the Imagination. The ChromeDome might have yielded more neutral results, while still providing 180 degree illumination.
Looks like I might be back to Fong's web store....
