if you can shoot from the building opposite, (or a cherry picker, mast or whatever) my
[a href=\'index.php?showtopic=43338\']Virtual Viewpoint technique[/a]
can be very useful, and allow you to get the foreground in, and view the building from ground eye-level, without stretching.
I look really forward to see an image done with this technique.... really I think, it will be some kind of a challenge to mix, let's say 10 images, where everything in the background, and the building for that matter, have a different perspective, due to different hight of viewpoint of the time of capture.
I know from real life shooting, that if I move my viewpoint 10 millimeters when doing a stitch, for example with a dslr and a shiftlens, then nothing lines up perfect anymore....( thats why a tech camera, where the lens can be fixed when stitching, is so handy) so aligning 10 images, where you move your viewpoint 3 meters between each capture, is a thing I really look forward to see the outcome from.....
At best, I think you will see an image with 10 different perspective's - one for each viewpoint - how this will give you a feeling of viewing a building AND surroundings, from ground level is beyond me.... but please, prove me wrong with an example.
sorry for the rant, but you are presenting here an unproven technique as "very useful"
Marc here in the opposite, presents in a perfect way, a technique with a lot of samples and how to's - so everyone can enjoy it and use it if they want - thanks a lot Marc!
