Not a church. It is the county courthouse. Thanks everyone for your help. Lots of good ideas. Looks like I should have been on the roof of the county sheriff's office instead of on the street in front of it. :D :D


If you are either above or below the midpoint of the building you are shooting, there will be some perspective distortion. How noticeable will depend on how far above or below the midpoint you are standing, along with how wide a lens is being used.

You are also using a bridge camera, so you need to check leveling, and other options in post processing.

The main reason is that for larger items you generally will NOT be holding the camera perfectly vertical. If you use a tripod with a bubble level, center the bubble and the perspective distortion will be limited to that caused by the lens, HOWEVER you might not be able to get all of the building included without using a wider angle lens.

I straighten the sloping wall in photoshop for you


Hard Rock,

You did improve the tilted verticals, but there is still more work to be done in making the verticals vertical and parallel to each other.

Try going back to the original image and set the horizon to horizontal level, then take the center corner of the building and make it vertical, finally use your perspective tool to fix the leaning verticals, this should also make the outer vertical edges become parallel to each other.

The 'vertical distorsion' effect is a natural property of lenses and is expected. In cameras designed for architectural photography the film plane was made to be tiltable. One had to be careful to angle the camera such that all 'tilting' was perpendicular to the camera vertical axis.

To a limited extent, such distortion can be remedied in Photoshop using the Crop tool in Perspective mode.

Lots of suggestions & options here so I'll put my 2 cents in also.
I have the SX 50 HS too.
You probably took the shot at the wider end of the lens. (28 mm,) so the perspective will be exaggerated a bit more. If you try to straighten the perspective so that all vertical lines are parallel, to me that would be a bit off because the perspective is natural when you are looking up at a tall object.
LR 5 has Lens Correction for my Nikon lenses, but not for the SX 50. However, you might try to enable lens correction and see what you get with any of the Canon lenses listed.
Or, you could have taken the picture from further away where the perspective would be less pronounced.
I seem to remember something about being able to adjust "pin cushion" in PSE, or maybe Photoshop.
If it were my picture, I'd level it and leave the perspective alone or even get closer to exaggerate the perspective.
I'm probably wrong and somebody here will say so.

Shot with the SX50. The sides of the building slope inward toward the top. Is this camera specific, zoom, or camera settings? Did not have this problem with my Oly.

Thanks in advance for your help.


I'm afraid that most of the answers to your question here are incorrect at best. Here is a fairly short explanation that should answer your problem.

Hope this helps you all for future reference.

Not trying to start any arguments...but I have to disagree. The building is NOT distorted!
How do I know? I downloaded it and used a straight edge along the left and right edge of the building, as well as the corner near the center. All the edges were perfectly straight.
I then measured the distance between the right edge and the left edge near the top of the building and near the bottom. The outside edge lines taper naturally so that the distance between the edges at the top is narrower than the distance at the bottom, as they would appear in normal perspective.

Actually I did not say that the image of the building was distorted. I was hoping that the video would explain that it is NOT distortion, but natural perspective. :-)

It is soooo much easier to see something wrong with the image when you are sitting in a comfortable chair sipping a cold one and taking time to study each and every aspect of the shot.

The same thing is not quite so easy to accomplish while in the field.

I have found that the more I use my camera the more I see things that I should have done differently.

Unfortunately, not all things can be avoided while in the field but we all struggle to address as many of them as possible.

I think structures like this tend to often be a problem. Even though our eye may see the distortion in the viewfinder our brain tells us that it is normal and OK.

Do not listen to the brain behind the eyeball. lol

When you have the time take several looks at your composition. Change positions if possible and recompose.

When you see what is a potential problem with your image and do what you can to minimize those problems then take the shot and fix anything else that you can in post.

Finally take a number of shots from a variety of different angles while you have the opportunity.

Thanks for making me think! Now that I have verbalized (sorta - texturized?) these ideas maybe I will have more success applying them to my photography.

Enjoy!
