screenwriting - Shots in a spec script?

I'm writing a feature-length movie screenplay - well it's still at the story stage, so I haven't started to write the screenplay itself yet. I have been reading wordplayer and a few scripts to see the structure.

I've got one scene in mind where the POV is really important for maximum effect. I want to describe that the camera should be inside the boot of a car (trunk for the Americans here), pointing back at a character. It's similar to at the start of Pulp Fiction when Vincent and Jules get the guns out of the boot.

In terms of the story, it is obviously irrelevant where the camera is placed. But this is a comedy and the camera angle will make it funnier.

Should I put in a camera direction for this? I don't intend to direct the film myself, so want to do whatever would maximise my chance of selling it as a spec script.

Thanks
