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).

Sandman:
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.

Floyd L. Davidson:
You can't change the perspective in
post processing.

Sandman:
With modern software, you can.

Floyd L. Davidson:
You can not.

Sandman:
Incorrect.

Floyd L. Davidson:
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.

Sandman:
Learn to read, Floyd.

Floyd L. Davidson:
Yeah, right!

Sandman bites the dust... one more time. (And poor nospam goes
too.)

Sandman:
Will you let us know if you get the chance to learn to read
anytime soon?

I'm not holding my breath.

We all wish you would!

Is this another case of you are going to tell us how to define words
in English? Should be good for a hoot.

Please provide a dictionary definition of perspective that matches
what you think Adobe was trying to say (using the wrong words, BTW).

You know, what I wrote is still above in the quoted text, and your inane response
is as well. Re-read what I wrote a couple of times and then see if you can have
an adult explain how what I said and your example has nothing in common.

This is a classic case of Floyd trolling - he joins a thread where one of his
"nemesis" have posted, tries to find some detail he can quote of context and
claim it is incorrect, while failing to understand what was actually written and
also failing to understand what can be done with modern software.
