That is what most of us do now. Chopper rental has gotten soooooo much cheaper since covid19 came around. And since the administration has retracted most federal regulations you can now fly choppers in places you never could before.

Since I don’t like all that noise from the choppers I just use shift lenses ... but then again, I’m most usually swimming upstream anywho !

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.

I use DXO for perspective correction too - however with large building I reduce the correction a little - this leaves verticals a little way from true vertical but leaves a more realistic result. In fact a "perfect" correction can look a little non-vertical to the naked eye.

Plumb and vertical is dependent on how plumb and vertical you are not the camera design.
Hold it straight and all will be straight. Now if you tilt any camera up you will get converging lines. (Yes I know about view cameras and TS lenses).
So regardless if the FF or crop camera or an 8X10 camera tilted up as is will have converging lines and if you hold the camera off level the building will look off level.
It is you not the format.

Convergence toward a vanishing point is what your eyes actually see so there is no “distortion” involved and nothing to “correct.” What others are suggesting is distorting your photos so that they appear to be taken from a different perspective.

It all has to do with the angle of the camera. I'm not exactly sure what you mean here, but even the human eye sees the building as not plumb. The top is farther away, so it looks smaller, and the sides are tilted inward. That can be corrected in processing.

I don’t know about step ladders that tall (and I would hate to climb all those steps 😎), but seriously, this is an area where camera-equipped drones have been making a real impact.

My cousin married a realtor who got a drone for photographing homes he was listing. It started as a toy and became a useful sales tool. He is or the athletic type and enjoys flying the drone around a property, rather than hiking. And, he doesn’t have to deal with fences or dogs. He is not the only one who has adopted this technology.

I guess you could think of drones as tools—just like you think of tripods.

Some camera's have help inside them. Nikon, in the retouch menu, you have straighten, distortion, and perspective control, all help a little.
Line converge toward the top of buildings. You can control this simply by moving away from the building so your not so close. Wide angle lenses tend to distort more than normal and telephoto lenses.
You can also go up into one building about 1/2 way and shoot your building out of a window. About 1/2 way works well.
OR, you can do it in post production, many have this feature to straighten out a building.
A FF and cropped will converge similarly.

The eye sees the building as unplumb when the eye is unplumb.

The word is "plumb". The fruit "plum" is incorrect.

The sensor size is not an issue.

Just have the camera (DX or FX) level front to rear so it is not pointed "up".
ie. perpendicular to the building.

If the building is tall and will not fit in the frame, rotate the camera to vertical/portrait
format and/or move further from the building, and/or use a wider lens.

You only need a 268' ladder.

The best answer (as some of us already mentioned) is to get a "TILT AND SHIFT" lenses.
A majority of the large format cameras have this kind of perspective control built in for the movement of the lens.
Some 35 size cameras (Canon and Nikon, maybe some others) offer this kind of a special, manually operated lenses. Because or their much wider coverage, these lenses are expensive.

Keystoning, deformation. Thank you for explaining these 2 words.
Are there other popular (ACR, LR, ON1, Luminar, Topaz?) plug-ins that can do these tweaking aside from DXO ?
