Depends exactly what you want.
Most shots these days, you have an extra ship (like a shuttle or my favourite, the TARDIS) floating around. If you load BC in TestMode, you can open up the console panel with the "?" button and type in a code that can resize models and make them invisible. I don't bother to do that so I blast the TARDIS so much so that it just disappears
Then you set up your ships in position, transport over to your invisible ship and just float around and take pictures.
You can also EditMode (also found in the console (I think) of Test Mode) but...thats not my area of expertise.
