Thanks for the report, My2tailwaggers
Hey! What happened to Trip and T'Pol?
Apparently, they broke up sometime after "Terra Prime"
Pfffft. I don't mean that silly holodeck program. Barclay tinkered with that while he was drunk, to mess with Riker's head. I'm not buying it.
This is what I'm talkin' about.
You will note that Trip is closer to the camera and it is a slightly top down shot. That is a textbook method of giving items/characters to the back greater perceived height. If it was someone else in the scene with Trip the camera angle would have been low to make Trip look taller. They do this throughout the series.
I'm not clear on the point you're trying to make. Bakula is 6'0". Trinneer is 5'11".
Here's a full-body shot of both of them, standing side by side. The height difference would seem to be a non-issue.
