He'd actually have to use one to know anything about the subject; his answer isn't surprising... Take Care, Dudley

That would work but it would be impractical (expensive) to make a wide angle lens with a large enough image circle and would take a lot stronger gyro/motors to move it that far.. although, hmm, it would be the very same motion, just a lot more travel. It would be interesting to see that idea implemented in a video with a tilt (pan up or down) that kept the verticals vertical using a stabilized shift lens. It might look more like panning across a still shot though I'll bet it's been done, cinematographers can be very clever and sophisticated and have the budget.

By everyone telling you that the exposure is wrong in every one of your shots. If not the exposure then the focus. If not the focus then the composition. If not the composition, then a combination of any of them. Yes, you SURE figured out how to do it alright! LOL! Do everyone a favor, take up Braille or something. Something you might actually be capable of comprehending now.

A budget solution that might work for you is a steadycam type thing which would simply be a weight hanging from the camera on rigid rods... kind of wide, so it hangs down firmly establishing level. If the weight is long and horizontal, you should be able to feel when the 'roll' is off kilter. You could choose to tilt up or down and feel the weight to know how much tilt it'll look like. The more I think about shift though; the perspective correction shift lens wouldn't work with gyros or weights. It would be like panning up a flat poster but you don't tilt up, you fly over it like aerial photography. So, the lens would be on a tripod and you lift the camera across the scene. For a camera without a big steadycam counterweight, you'd need a powerful gyro to keep the lens from tilting and a dial for raising & lowering the camera with the lens fixed. And it would be counterintuitive movements, I think, if even possible without a tripod. Interesting idea though.

I would be proud to know you. Some of these people probably don't believe that Beethoven was deaf--that is, if they ever heard of him. Allen |
