Most of you are probably sick of seeing these posts by now, but I was hoping for some advice.
I've always had quite a few photos rejected for badcameraangle. In some cases I looked at the photos again, agreed with the decision, and made a change. In other cases, I disagreed and didn't bother re-uploading them.
In the past few days, I've had some rejections for that same reason that confuse me a little. These photos were taken from 3- 5 stories up. This being the case, any time I shot anywhere but directly in front of me, the photo would have the appearance that the ground is sloping (I believe this is a simple law of perspective). I edited the photos so that the vertical lines, namely corners of buildings in the background, were completely vertical. I didn't think lightposts were a good bet since if you look at a series of them, you'll see that most are not completely vertical.
These photos were rejected for badcameraangle, and I really have no idea what to do to fix them. It would appear that either there's something I'm not seeing, or that the screeners will only accept a photo taken from above if the subject is directly in front of you.
I would appreciate your advice to let me know whether this is a lost cause or not.

I appreciate the comments, guys. While the angle of rotation is slight, I do see it in all 3 after using the measure tool. Thanks for that link, Jan. In all of my time using Photoshop, I never even looked at that - I would always just eyeball it using the rectangular marquee.

Hi, Tim - nice pictures. Sometimes the ground is going to slope upward or downward depending upon the position from where you took the picture. The thing to do when editing the pictures is not to concentrate so much on the runway, but look more at other things in the background, such as buildings, light poles, and signs. In the wording of the "badcameraangle" rejection, the concern is more about the plane being level related to the horizon. Sometimes in order for the horizon to be level, the plane or the runway may seem to be sloping upward or downward.
I don't know which image software you use, but Photoshop has a grid feature that you can activate, which will superimpose a grid over your image. I find it very helpful in determining whether or not an image I am working on is level or not. In the case of the pictures you listed in post, I think they are very salvagable. Open them up in your image software, and if you have the grid feature, activate it. Then try rotating the pictures so that the light poles, buildings, and signposts align themselves with the vertical lines of the grid. This may result in the runway sloping downward or upward, but as long as the horizon is level, that is ok. That way, even if the ground is sloping, it will be level, when compared with the horizon.
