Hi All,
Jou might know situations when even 10mm lenses do not provide enough "wide angle" to capture a scene??? ....
Did you know that panorama tools can do more than just stiching horizontal panorama scenes??!
Let us have a look at the Grerman Reichstag Dome (BERLIN)... quite interesting architecture ... I think...
Interesting enough .... Wikipedia does provide a pano shot of this dome.
I did it in a very different way!
Well, the SIGMA 10-20mm DC is the "shortest" wide angle lens available (except fisheyes ... which do not work with architecture!)
Anyway ... its focal length is too long even at 10mm to shoot the dome completely.
The only way to make it is to do two separate shots, which overlap a bit.
I did that freehanded.
Next, I stiched both shots using ADOBE's Photomerge function (part of Photoshop CS3)
Finally, I corrected perspective and distortion and did a sensible crop ...
well, this way you can do wide-angles, which cannot be done optically. Another point is a considerable increase in resolution .... simply because you combine the pixels of more than one frame.
Some other examples ......
The Dome again (both frames @ 10mm)
Then the artificial "wideangle" ......
Finally an example I did in a dimly lit museum .... making use of the SIGMA 18-200mm DC OS (@18mm) using the OS freehanded.
This "artificial wideangle" is composed from 4! single 18mm frames. There is absolutely no chance to shoot the dino completely with optical measures.
Even the 10mm SIGMA lens did not manage the job there. The other thing was, that I had to use the OS-system ... otherwise I would have blurred the shot.
See you with nice pictures
