Hi all,

I'm totally lost here. Level rejection:

http://www.airliners.net/addphotos/rejections/big/20080828_abSM58.jpg

Was leveled using the horizon. The building on the right is leaning left because of the camera angle (pointing upwards) and wide angle lens.

Should I appeal? Or, otherwise, how do I fix it? Which way to turn?

Any feedback would be greatly appreciated.

Cheers,
Andrei

Hi Andrei,

One of those cases where you shouldn't level according to the horizon!
You said it yourself, this is a wide angle shot, and with one side leaning inwards, you would expect actually both sides leaning the same. Accordingly, having the left side horizontal looks odd, so you'll need to apply some CW.

Hope it helps  Smile .

Thanks, guys. Nice to receive feedback from two screeners. No non-screening photographers - does that mean that it was also slightly confusing for most of them?

And one of the cases where some hint as to where to turn from the screener in the rejection email would have been much appreciated...

I do see your point, but it is not exactly a fish-eye lens, it is only 17mm, which, taking the sensor size into account, the equivalent of 27mm for 24x36. On another shot successive to this one, I can see a bit of the horizon under the starboard wing. The measurement using the Photoshop tools, as well as visual impression, shows very little curvature to the horizon. Leaning of the hangar is mostly due to the camera pointing upwards.

I see you point, too, but IMHO the example you provided is not very illustrative. Seems that the photo actually requires some CCW, as the verticals on the left lean inwards a lot more than the verticals on the right.

But anyway, thanks again. I know from my previous experience that leveling photos is no exact science. I agree that the photo in question might look better with some CCW applied; in fact, I've already done it and re-uploaded.

Cheers,
Andrei.

Don't know what lens you're using, but my Canon 17-40 f/4 L shows at 17 mm quite some distortions, which will only gradually diminish towards the 40 mm end.

Yes it was only a typo ...

It also depends on how much you crop, right? Distortions will be much more pronounced at the edges of the shot and less - towards the centre. This particular shot was cropped quite a bit down the bottom - the horizon was about one third of the picture hight from the bottom edge.

What is your camera?

All right, I already saw in your profile - same sensor size as mine.
