A question from a non photographer. If the lens is closer to the glass than the distance from the flash to the lens, still true? Any suggestions on how to make it work? We are all dying to see the interior.
All you need is enough difference in angle that the flash doesn't bounce off the window directly into the lens.
The ideal solution would be a portable strobe placed well off to one side. Failing that, getting the lens very close to the window and using a lens hood will work. You can probably even get most of what you want by taking the picture into the car at an angle with an on camera flash.
