Thank you yes I've used the auto correct and the manual correct in Lightroom, But what I was trying to figure out is 1, is there a difference in that perspective between a full frame camera and a cop sensor, And or if a tilt shift is basically the only thing you can use to do it (IN) camera.


The angle of view would have effect but not sensor size as long as you have the same angle of view.

A full frame camera could help with the keystoning but only because you could use a wider angle lens and not tilt the camera up at an angle as much. I took this photo in Richmond, VA. I tilted the camera up at an angle. There's keystoning and also volume deformation. Volume deformation is causing the smaller wings of the building to be stretched horizontally. I used DxO ViewPoint 3 to correct it. I made a diptych in Photoshop of the before and after.

Will a medium format camera capture even more beauty?

I think not according to CHG_CANON.

Yes it definitely will. And Large format will capture even more and more beauty.

... this is keystone distortion, and it doesn't matter if you are using a cellphone camera or an 8x10 view camera. If you tilt the camera up the verticals will converge towards that vanishing point in the sky.

Keep the camera level and square to what you are shooting. In addition to the vertical perspective issue, horizontals will also converge in the same way if your camera is not square with the plane of the building.

A lens with a shift feature, shooting from a higher vantage point or post processing are the only alternatives if you don't want to buy a shift lens. The post processing alternative almost always has a corresponding loss of image and loss of image quality.

However, if you have a wide enough lens you can sometimes just keep the camera level and crop out the foreground, leaving you without the keystone distortion you get when you tilt the camera up. You will still lose lots of image, so you will need to compose your shot with that in mind.

Best summary yet! You nailed it.

When taking photos of buildings with a crop sensor the buildings Are not plumb/vertical, Is this condition less with a full frame camera. And other than post processing and/or a tilt shift lens, Is there any other way or technique to get buildings trees etc to be plumb/vertical sooc.


No, that has absolutely nothing to do with being a "crop" camera, or full frame camera, it's the person behind the camera (the lenses he uses and from what standpoints he shoots, etc.)!

This is not only not true, but it has nothing to do with this discussion.

Thank you all for your responses, I found when using Lightroom to correct the image as mentioned earlier you do lose part of the photo at the bottom, and it seems to distort the building aswell. But my initial question was is the distortion different if you take the same shot with a full frame camera compared to a crop sensor. thanks again for all of your responses.

So this puts all attempts - current and previous - at more and more beauty completely to shame -

Why not use as helicoptor, or a drone, to achieve the correct viewpoint(s)?

That's even better than my very very tall ladder suggestion.

Your hunch is correct: luck is no substitute for hard work and having a full-frame camera.

All other things being equal, lens quality, angle of image sensor plane, added distance for equivalent field of view, F-stop setting, then no. Note all of these things involve optics.

The sensor size won’t change distortion but the optics can. It is hard to divorce the sensor from the lens. You need to consider both.

Yeah, I was going to buy one of those but it won't fit in my bag.
