You could do the print screen thing, or you could go here

and get the M6 model editor v2. If you do this, the amount of masking that needs to be done is almost nothing since the background is already totally black. You can position the ship any way you want to get the best looking angles too!
I’d also suggest using ACDsee to do the scaling, and if needed, adjust the brightness.
I’ve found I can do about 20 ships per hour that way.
