Photo Acceptance - Post-Screening (Chukcha)

Wed Mar 25, 2009 12:10 pm

Had this one rejected for level:

The Screener left no personal message, and neither did the Head Screener on appeal. I have no clue what they thad in mind - CW, CCW?

The photo was taken from the ground level, with the camera pointing slightly upwards, focal length 13mm.

Any input would be much appreciated.

Cheers,
Andrei

Hello Andrei,

it looks like it is leaning a little bit to the left and needs some CW rotation..

I would always judge a wide angle picture not online with the references in the background, but also the overall impression of the picture..

Hope this helps!  Smile

Cheers,
Bjoern

Personally I still prefer to find some piece of evidence to base my leveling on.

Here, there are no central verticals, but

The mast on the left slants about 4.1 deg
The green container on the right slants about 5.5 deg at the same distance from the edge
Difference 1.4 deg, suggesting that 0.7 deg CW is needed

And I do think that looks better.

You can measure more accurately in the original, or double check with the white container on the left vs the red one on the right, they're also about the same distance from the sides.

Wouldn't CCW correction than not even emphasize the problem??? Big grin

And I don't think the mast is a good reference anyway, looking at the white container, is has a complete different angle in my opinion and is more reliable  Smile

Yes, it would! I meant CW, sorry, I edited my post. Thanks Bjoern.

The mast may not be enitrely reliable, but it's only normal that it slants more than the white container.

I guess, sometimes it's just a matter of personal taste of the screener... In this case, no levelling or other further corrections may help in any way. Just remember that there are human beings an not machines sitting behind the screens, so decisions are personal decisions.

Thanks guys, for all the replies.

Over the three years of uploading here, I found out that leveling pictures is not always as straightforward as pure math, and there have been many arguments here on the forum. It all boiled down to one thing: when the references are not dead obvious, the overall impression may be more important.

Maybe it is leaning to the left, and I just don't see it... Anyway, I'll try the mathematical approach this time. I've just measured using Peter's method, and it comes to slightly over 0.7 CW. I'll do that, and I'll keep my fingers crossed  Smile .

By the way, how does it work now with the acceptance threads - is it one thread per rejection or per photographer now? I have an inquiry concerning another picture now; should I continue in this thread, or should I start a new one?

Cheers,
Andrei

Wow! What a great aeroplane!  

Glad you sorted it out, Andrei.
