You take a wider shot and then crop. Photoshop can help you fix perspective

You can't change the perspective in post processing.

Photoshop lets you easily adjust perspective in images. This feature
is particularly useful for images having straight lines and flat
surfaces‹for example, architectural images and images of buildings.
You can also use this feature to composite objects having different
perspectives in a single image.

My experience is that this a faux change in perspective. I have tried
this on a nuber of images and found that it introduces a number of
visible distortions. DxO is noticeably better but still is not
perfect. Moral: you have to place the modern camera in the same
position as the original. Afterall it's sight lines which determine
perspective.

The best way is to determine the spot from which the original was shot,
and the focal length and aperture of the lens used at the time, and
duplicate it. Everything else is a fudge- and sometimes confection is
needed.

Focal length doesn't affect perspective. All it does is affect field
of view.

Was there a more or less standard lens and preferred focal length in the
1940's? Were they Brownie shots or large format?
