The best visual effects are pretty seamless. You don’t know they’re there, basically. The fact is, on a decent production- even on small ones- it’s quite common for us to do a whole lot in the visual effects arena that the typical viewer won’t notice, unless you saw the original shots. Don’t like the view out the window? Easily changed. Don’t like the sky above? We can change that. Actress has a pimple? Digital makeup. We’ve created whole worlds on greenscreen stages for clients.
Speaking of small productions, here’s a really simple, low-budget VFX shot for an app promo we did. We didn’t have the budget to bring in a Hong Kong taxicab, but the client really wanted one. So we brought in a normal car off the street, and made it look like a Hong Kong taxi, including putting it into a street in Hong Kong, complete with window reflections and more.
