Hi, I was curious about this so I did a Google search for "crystal Balls" amongst all of the images of actual solid glass spheres many indeed did show the reflection of the highlight on the opposite side of the sphere as in your image, and some where it was not so evident.. I believe it depends on the angle of view and also the environment reflections, background etc, etc..
Check the images on this page: http://theunicornshoppe.com/store/index.php?main_page=index&cPath=92_31 I think the reason it is unusual is that you seldom see a glass sphere lit by a single point light with plain environment and background etc.. As in these examples and your render.

I am mostly doing lighting tests and trying to achieve what I was able to do in my other favorite program Cinema 4D R8. Here is a sample of one of my experiments. I think that there is a problem with the glass sphere. The one specular highlight should be there, but I don't think that the other one should be. (Unless the sphere is hollow like a soap bubble. Which I don't necessarily want it to be.) Is there a way to keep a specular highlight from reflecting off the opposite surface of the sphere? -- -- Henry Tjernlund http://www.renderosity.com/mod/gallery/browse.php?username=henrytj http://www.modelmayhem.com/HenryTjernlund http://imdb.com/name/nm2519729/ http://www.myspace.com/henrytj http://henrytj.deviantart.com/
