hey ive always heard of "fish eye" where you can render and it looks like a huge bubble sorta, anyone know how to do that, and / or any other cool things like that

Yes, please let those who know speak up! i'd be interested to hear. Perhaps it has to do with the FOV in the camera setting? And setting it to wide angle? Those are the first things that come to mind. Not that i actually know...

Nfred, you got it right. It's just adjusting the depth of field angle.

I think you can only go to 180 degrees on field of view. A true fish eye gets 360 degrees. You might be able to fake it by using a sphere as a mirror. the F.O.G.

Bryce will render Panoramic images with 360? (horizontal) field of view. The verticle field of view is more like 115?. A "fisheye" is approx 16 - 8 mm (80 to 180 field of view). A 180? image is also a "hemespheric" image (1/2 of a full sphere). Fisheye images and Panoramas are well-covered by Helmut Dersch with his freeware PanoTools (Java,Windose,Mac) at: http://www.fh-furtwangen.de/~dersch/ There are many, many tuts & links to various aspects of imageing & conversions from one focal length to another, rectiliniar to perspective, distortion correcrtions etc. It is a lot of stuff to read through & there is a learning curve to it but well worthwhile. Another quick fisheye creator (for MAC) is DeFish at: http://www.iqtvra.org/DeFish/index.html Apple also has some utilities for makeing panos (Windows & Mac) at: http://developer.apple.com/quicktime/quicktimeintro/tools/
