My proficiency in levelling shots has improved over the past year. Every now and then a difficult and very subjective level situation appears. The shot below was rejected for level. I thought it felt right after I levelled it, and the PS grid lines aligned with the vertical lines on the walls of the multi layered/storied hanger at the center of the shot. The horizon cannot be judged from the tree line as evidenced by the C-130 which is in a lower area. The angle of the SNJ-2 Texan has not helped matters. McGuire Air Force base appears flat but is actually undulating with small rises and shallow depressions.The only reasonably flat areas are the runways. Your help as to the best way to level this shot will be appreciated.

Thank you Tim and Steve for your prompt response and advice. I have done a complete re edit as I cannot do a CW on an already edited shot without losing quality. I would appreciate it if you guys would re evaluate this new edit.

Thanks once more.

I have to acknowledge that I have always found the levelling issue fascinating. Yours is another excellent example.
I would agree that your first shot does look in need of a little CW rotation. For me there are a few verticals in shot that give the impression of leaning very slightly to the left. I am thinking particularly about the right edge of that smaller building that is cropped on the left (though the verticals it has on its surface do look level - a conflict there for you) and the edge of the building in the middle. The fact that the horizontal of the smaller building roof on the middle/right also slopes from right to left only 'confirms' the impression in the brain that the whole picture is sloping.
In the second edit I think you have corrected one of the key points - that edge of the building on the left. But now one of those vertical lines on its surface, right by the edge of the crop, looks to lean to the right. This might trick your brain into thinking the photo needs CCW rotation now, if you are not careful . But the building edge itself looks right to me, and the main vertical in mid photo also does not have any sense of leaning either. So I would be more hopeful on that.
One trick I use is to grab the top of the toolbox in PS to move it around the image and use its edge to put up against verticals in the photo. If you do that with the above vertical references, it looks to be spot on now.
But those vertical lines on that building on the left are not vertical, so that is misleading (it is they that look spot on in your first image). Maybe worth a note to the screeners.

Quoting Psych (Reply 4): Maybe worth a note to the screeners.
This is an excellent point. Sometimes, whatever was used to measure level is subsequently cropped out of the image. In cases like that, I always leave a note for the screener. I'll also mention, especially if a shot "looks unlevel", what was used to measure level (e.g. edge of building in background).
I suspect that some screeners only ever go by the visual look of a shot. I've had level rejections where a building in the background is clearly (and measurably) perfectly vertical.
