Matching the aspect of ancient photographs.

I have some old photos of my locality going back about 70 years.

I want to compare these old scenes with their modern equivalents.

How does one position a camera (and lens) to match the ancient scenes
so that the old & current images are superimposable (or nearly so).

You take a wider shot and then crop. Photoshop can help you fix perspective
differences as well, but the closer you are to the same spot when you take the
pic, the better.

You can't change the perspective in post processing.

To get the same perspective it is necessary to shoot from the same
location. Choose the focal length to match the framing.

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.

With modern software, you can.

Not the same thing. What they are saying is it will
align a single object, such a vertical line that are
tilting.

The problem with duplicating the perspective in a new
image to be the same as an old image is quite different.
Perspective means that some distant objects are hidden
by other closer objects.

That can't be changed in post processing.

You can not.

Take a picture of a car parked in front of your house
from across the street with a 105mm macro lens. You'll
be able to see a great deal of your house.

Now use the same camera and lens to take a picture of
the same car, except shoot from 3 inches away from the
car door at the door's midpoint. You won't be able to
even see your house, much less any of it's details.

That is the perspective which is important in recreating
an older image. It depends entirely on the location of
the camera when the picture is taken. It cannot be
adjusted even slightly in post processing.

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.

FLD is right: You can't change perspective in post. You can make
keystone adjustments, but that is not the same thing.
