Pls Help With Level

Sat May 19, 2007 9:22 pm

Hi mates,

Need your opinion and assistance.

This photo was rejected for level with comment on CW rotation.
http://www.airliners.net/addphotos/r...ections/big/20070519_LED-above.jpg

Its true that airport itself looks a bit fell to the left. But I hecked the level by horizon line (as the most true one as I think). It is obvious effect as far as the picture made from above and not directly from 'cener line' of the picture.

I made another attempt:

Now airport looks in oreder but the horizon needs CCW.

So - your comments and advises a very welcome.

Regards,

Fyodor

Yes, the new version looks better. I think the horizon looks off because some wide angle lenses have distortion that is not a perfect sphere.

Exactly. If the image was taken through a wide lens, then the horizon is not that reliable and you should take the verticals at the airport instead. Amazing shot, Fyodor!  thumbsup

Thanks guys!

It is indeed. But you can try to check the real horizon line by two marginal points.

Thats what I do often but I had some rejections on that way as well. Some time, especially at hilly airports leveling is going to be difficult thing. Especially if you need to cut your image and present only part of it.

And it was rejected again twice including the appeal...

I put it here, as far as it was deleted after appeal:
http://www.airliners.net/uf/view.fil...1494&filename=1180189154UCKwO3.jpg

I'd sent quite upset comment at appeal (realy sorry for that), but I just did what was at screener's comment first time.

Well, what to do? Could you advise me please - what is the right level for this picture?..

Thanks in advance.

Regards,

Fyodor

Try to level off by using the taxiway connecting left and right runways as horizontal reference.

Thanks mate, but that was the first I did after the first rejection.

Fyodor.

I believe that Jan had it right in his comment - the problem was the distortion caused by the wide angle, resulting in the horizon at the left and right 'drooping' quite significantly.

It is possible to correct such distortion - I made an initial attempt in this example, which is not perfect (the result would be better working with the original), but it gives an impression:

Big version: Width: 1024 Height: 683 File size: 659kb
Fyodor's Photo

Now that horizon is a lot straighter (and could be improved further, as the middle is still slightly higher than out at the edges of the shot). I think that would then resolve the issue for you. However, it would be interesting to know whether this would be considered an unacceptable 'manipulation' of the image.

Let me know if I can help some more.

All the best.

Paul

Paul,

Many thanks as always!

It is good idea but I think it is bad editing.

Another point - this effect is part of photographing. It is not daily shot you can make few attempts for to improve it changing distance - you need wide angle lens for it. It would be more easy to solve this solution - just to crop the sky and level off by the rwy. But it will seriously reduce the potential of the shot. Not a good idea to do it in my mind. And, sorry, but I can't agree this shot is bad and not for A.net.

So, what I'm looking for - is advise how to level it without bad editing? Or - opposite - if some of your think it is not good to send such photos at all - please say - your opinion is important for me as well.

Regards,

Fyodor

Hi Fyodor.

You are very welcome.

You have my sympathy here - I agree that it is a shame such a photo is not accepted, as I am sure there are many who find these overviews very interesting. Assuming that we are correct, and that it is the horizon that is the issue, then I also agree that such editing might be considered 'manipulation'. In that case, and given that you need a very wide angle to capture such a shot, I think there would be a good case for arguing that so long as the horizon is 'balanced' around that middle higher point - i.e. 'bends' equally to either side due to the distortion - then it should not be 'punished' for not being level. I can't really see any other way of leveling it.

I wonder if there will be any crew clarification on this...?
