These pics were taken about a month ago. It was my first attempt to photograph this very large and heavy glass sphere I purchased. I have since photographed it three more times, getting more elaborate, and trying to build on ideas I thought of when I was photographing it each week. I discovered my favorites are the ones of the laser beams behind the sphere which created very nice patterns in the sphere. Many of the ones posted here are the beams going thru the sphere and while still looking very nice, look much better in the three photo sessions taken after this one because of better beam placement. Though, when using different diffraction gratings and projecting the beams thru the sphere, the beams form some nice geometric patterns when coming out of the sphere on the other side. In the sessions taken after these, I was really able to some beautiful patterns in the sphere. But this was my first try with the sphere. I eventually used some fan diffraction gratings and mirrors to get even more things going on inside the sphere. Also in this session I used 2 -405nm 500mw's with fan diffraction gratings to project thru the sphere. You can clearly see the green lines and sphere turning green because of the way the 405's interact inside the glass which came out really well, Also a 473nm 100mw produced some nice diffraction grating shots. Enjoy and have a very Merry Christmas and Happy New Year!!
