Thank you.
It looks to me like the right picture was taken from at least twice the distance with a higher power lens.

Yup - in the picture on the left, the camera was tilted upwards. This changes the perspective and causes vertical lines in the image to converge, which makes the building look shorter than it really is, and as if it is toppling over backwards. It's a little extreme because it is a relatively wide angle lens (17mm on a full-frame DSLR).

In the picture on the right, the lens was shifted up, with the film plane remaining perpendicular to the horizontal - this provides the true perspective with verticals staying vertical.

(Nomadd22 - as mentioned, the same camera, same lens, and same location was used for both shots)

In case anyone else is interested, maybe this will help. The black lines represent light falling on the film plane (or digital sensor) from the exact same angle. Normally to shoot something tall, you must tilt the lens back, but this causes the film plan to be out-of-parallel with the subject, so the subject appears to lean back. By contrast, a shift lens keeps the film plan parallel to the subject, but shifts the lens elements so that the entire thing can be captured:



This is not an easy way to construct a lens. Congrats Gerald, that is one amazing thing you've got!

Gerald, lately I've been shooting with my 24mm too and of course at the widest angles there can be distortion. A normal 17mm would be crazy, hence why you have that awesome TS lens. Some programs like DPP can correct for distortion - do you think that would work for a semi-wide angle shot of the Burj? I still know what you mean though; even if you angled up to fit the burj in the shot and corrected for distortion, you'd still be off vertical on the film / sensor plane.

What I suppose I'm asking is if you think I could somewhat replicate your shot with the 24mm if I was far enough away to capture the entire burj in one frame, then corrected for distortion?

Granted, I'd love to have / rent that TS though heh... Nice explaination.

It's possible to correct for the perspective in programs such as Photoshop. The problem is though that you either lose, or have to interpolate, a LOT of pixels in the process, which significantly impacts the quality of the image.

Clearly in the photo on the right, there is detail towards the top of the building that simply doesn't exist in the photo on the left.

(more examples of photos taken with the lens here - http://www.skyscrapercity.com/showthread.php?t=909126 )

Thanks for the info Gerald. It really puts a new perspective on things :p

Even with a larger screen here, I faintly see what you mean when you have the two BD shots in the same large image side by side.

Could you do a crop of both tops by chance so I could see it more closely please? I'm not doubting there is more detail in the top of the TS shot, it's just hard for me to make out clearly.

9/9/9 was the intended date, but it's mission impossible now. Maybe the cladding will be complete by then.

Now... uh... I'm sorry to ask: 12/2 as in 12 February or as in December 2nd?

It's that in the Western world, only North Americans put month/day/year for dates (which makes as much sense as minutes/seconds/hours ), but since there are many Americans here, I wondered.

I think that Burj Dubai will be inaugurated by December, just in time for a great New Year's party with fireworks and stuff. They have not announced an official date yet, but that's my personal guess.

Works will only be fully concluded in 2010, now that's an official prediction they have assumed.

Hi all.

Yes - 09 12 02 ( I use yr mo day - keeps pics in order) is the latest press release opening date. I too think this is the new date for the soft opening. As usual the general public is taken for a ride - the release said opening on that date - carefull not to mention full opening. Also not mentioning soft opening so everyone thinks the whole structure will be complete ...

I think Imre said it best in another thread - Dec 2 of what year ?

I'm sure the completion of the whole of the works will be in the first quarter or half of '10. As I posted many pages ago - there will be one or more press releases saying full opening will be later than Dec.

Apologies for the repost, but a picture paints a thousand words:

Sorry to say that but, it doesn't matter whichever expensive lens/camera you're using, the picture on the left is correct and the one on the right is distorted. I have been in that spot myself too, the building looks exactly like on the left picture. Anyone who has a a good eye or with a technical perspective drawing knowledge will see that.

What is wrong with vertical lines are not looking parallel on the picture? if your viewing angle is not parallel to the ground, of course you will have a 3 point perspective. seems like you want to live in a 2 dimensional world?

I'm not saying that you're pictures are bad or your lens is useless... But as with fish eye lenses, your lens shows the world distorted too. Saying that your pictures are the correct look of Burj Dubai is misleading the people who have never seen it before. There is no way you can retain the proportions correct, if your viewing angle is not perpendicular to the film surface. And that is more visible at the spire, which looks much taller than the real thing.


Edit: The picture on the left is also not 100% undistorted due to wide angle lens, but if you look at the building only, the proportions and perspective is exactly the same as you're looking at the tower from that point.

I totally agree. I've never seen bd for my self so i keep my mouth shut, but it always looks unnatural for me. And now im sure Mithat is right. Notice that spaces between the mech floors on the right picture looks like they would have different longs. I think that the only way to shoot bd to look right, and not falling back is to shoot from long distance with zoom. Using that special lens is just litle cheat, that makes look building unnatural.

127 degrees F? AND the A/C is on low? My A/C stays on high at anything over 95 degrees F (35C). Must be a dry heat!
