There's not full of jobs in the 3D world as I heard. Much are video games and video is involved. Though the very clean and high resolution 3D images are worthy in microstock.
I downloaded the trials of many 3D software during the last year but I didn't achieved even a simple house. Without courses or a tutor, it's kind of a complicated technic to learn. Photoshop is way easier.
Maybe 3D cameras will come shortly as there is already 3D HD television on the Japanease market. Maybe even photoshop could follow. Until then, mastering 3D give the liberty to create aproximatively any images you want with a perfection that photography mostly not achieve.
No surprise about a 3D artist being diamond, for sure
