I shot a photograph with a wide-angle lens of a magnificent theatre interior, fr om center of back balcony, with every seat occupied. Audience looks fine, theatr e looks fine, but actors on stage are blurred, as would be expected with 20-seco nd exposure. Client wants me to pose actors on stage, having them hold still for the 20-second exposure (don't worry, it's all standing and sitting--no ballet!) . The client wants to digitally combine that stage(d) picture with the wide-angl e, full-house photograph and use it for publicity purposes.
Digital controversies aside, if I use a long-focal-length lens for the stage sho t so that I fill my frame with the stage and the "wings" (which are ornately dec orated), will the perspective of that photograph seamlessly match the center of my wide-angle photograph? I've always believed that it will, but my lab guy says no. Remember, camera position is unchanged, and both pictures are on the same a xis; the long-lens photograph will be the exact center of the wide-angle photogr aph. Hmmm?
