Hiya Rap! Maybe i can help?!
I checked out that site... nice stuff, albeit a little too heavy in the file size department with the Flash stuff -- and i have DSL too. Anywho...
Those images ARE done in 3D. But that doesn't mean they can't be done in PS too... with a little bit of know-how and some good ol' object study.
I'll use that chrome ball as an example...
To do that though... you really need to study the source image and break down the object into very basic parts -- which in this case is just some simple grayscale sections, strategically constructed so as to fool the eye.
Like this example below. This is 100% Photoshop. And no fancy filters either... just the basics -- i.e. tools. I feel a bit silly trying to duplicate that exact image from that site, but it was the best way to get these points across.
My apologies to the original creators of this idea.
As far as reflections go... you'd be surprised to see just how simple they can be, by using the proper (
most appropriate) photo, and some gentle blurring. Reflections like the one above are NOT like the kind you see when the objects in the ball are very close to it -- like someone's face staring into the ball. The type of reflections used in this example image are distant objects. Therefore they're a little blurry, and not over-spherized. In fact, using the SMUDGE tool would be a better choice in this case to slightly 'bend' the reflected image to match the curve of the sphere's outer surface.
In my example image here, i've done just that, plus some simple gradient blending (
done on multiple layers) to "haze over" parts of the photo reflection somewhat. I wish i could go into some fine details with this effect, but it would take a fair bit'o typing to explain all the steps needed, and more importantly - WHY - they're needed;
which is something i really love to do in my tutes!
And if you have any sort of basic knowledge with PS, you'll understand how to create the light glow and subtle floor reflection parts. Just don't "over think" those things.
