Hi, today I was trying to create an effect in the keyframer which simulates a camera dollying combined with a simultaneous narrowing of the FOV. (i.e. changing of the perspective in KF). My problem is now that a camera move is a linear function while a FOV change is not (IMO it's a tangens). Result: the object first zooms away from my POV and then it zooms back in. I have tried (almost) anything with TCB and both Eases but to no effect. What can I do that the object stands rock steady in the middle of the picture and merely changes the perspective? Does anyone have any hints, clues, step-by-step-tutorials-with-glossy-pictures <g>? Any help would be appreciated. TIA Volker

There's an IPAS routine (with a demo somewhere here in the forum) that does exponential zooms, making the shot you want to accomplish easy. Take a look around (and perhaps someone with a better memory than I can remember what it's called). – G

Hi Gary, good to have G-forces in the background… <g>. I kinda knew what the answer was going to be as I've done some thorough research on this topic using the 'normal' approach. Anyway, thanks for your reply. Volker
