Geez, I was impressed with my Instamatic until now
At least the way you folks talk about this allows me to learn a few things along the way Thanks, and please carry on

I have always said, get it right in the camera. You can spend a bit more time getting it right at the time, which generally is enjoyable, or spend a lot more time trying to fix something later which is not always possible or at best it is pretty second rate. Personally I would rather not be sitting behind a computer.Nowadays, you can control perspective on a computer with ease but controlling perspective in-camera to begin with seems to provide more pleasing results.

These days cameras have plenty of resolution. If one wants vertical lines on buildings. Use a wider angle lens, set the camera vertical and square to the scene, then simply crop off the bottom of the image. You will have an image without buildings falling over & it take 30 second to crop.
I am contemplating getting a nice beefy tripod with a solid ball joint,,,,, but to shoot my gun from not any of my cameras.
But these are rather not cheap, so that idea will have to linger on the back burner while i shoot off my bipod or bags.
Something like this.
You can, and people have been projecting maps of a spherical earth onto flat paper for centuries, but we still have most maps showing Greenland as being huge for its actual size! The images always come out distorted in some way or other. For normal photography it is not an issue because you are photoing a very small part of the sphere, so there is a very small amount of distortion, but when you get to the field of view of a dashcam it is significant, and projecting straight lines to appear straight when projected onto a flat screen is not necessarily the correct thing to do. Even worse if you go to a full 360 degree view, although most people view them a section at a time, as might be sensible in a dashcam viewer.If you have 3D software you can project an image onto any shape and then render an image of that shape from any angle. Even through a shift lens. Before people had heaps of computing power it was the only way to divide up an image and render it on multiple computers to speed a job up.
Using a dashcam, you would need to use a telescope to project the image, then video the projected image, not too difficult to match that quality...Just to shift the topic a bit back to actual cameras! Here is a photo of the transit of Venus. Extremely lucky to get this shot as we had cloud virtually all of the time and further more I definitely won't be around for the next transit. 300mm + 1.4x + 2x extenders + 4 layers of solar film.
