The one good upskirt look comes from "Tears of the Prophets", and features some detailing in there, surrounded with blue glow. (Also note the CGI Mirandas
with additional impulse engines in the pod!)
Here's another look with detailing, even though the model itself is relatively crude overall. (This time note the yellow glow on saucer impulse engines on that Galaxy
; also, two standards of Miranda
Finally, there's the detailed death scene of the Valley Forge
. Despite the lights being out (for obvious reasons!) there appears to be some sort of detail in there nevertheless. Also note the aft torpedo tubes, protruding more clearly than in the physical model(s).
This is OT, but I never noticed before that those excelsiors in DS9 had the "correct" coloring of the blue highlights. Even though that's how the model was always painted, in ever movie appearance I can think of, they shot it in such a way that those blue highlights looked grey onscreen. Was always curious why that was. Since they kept that paint scheme on the model even in its various configurations though the years, I have to imagine it was a very deliberate and conscious choice. But it seemed like there was an equally deliberate effort to conceal this effect onscreen. Is this another thing like the gold uniforms that were actually green-ish? Or the R2D2 with black paneling? Anyone have any insights on this? So many mysteries surrounding this ship.
