I don't know of any RE photographers who do that. But maybe they do?
Seems that "stretching" photos to present a false impression is fraud.
Look at practically any professionally done photos of house interiors on zillow and look at the door width to height ratios.
At first glance you don't realize why rooms look so big but once you see it you'll get it.
Here's an example from a house mentioned above:
From this picture my impression is that that's a 42-48" wide door. Really though who puts in single doors that wide? Probably 30-36".
Check out that 2-gang switch plate. It's wayyyyyy to wide.
Also look at the window "panes"; they're way too wide as well.
If it was only the wide-angle lens, the height/width ratios should stay reasonable.
Here, I shrank the horizontal by about 20%. IMO the wall plate looks like it's in better proportion; the door now looks like it's 36" to me. Window panes look better too
But honestly it's probably still stretched too much. Here's an exterior shot of those windows:
I probably haven't un-stretched the horizontal
enough from that view, the interior shot is still way too "oversquare" - looks much wider than it is tall while the actual window is taller than it is wide!
Here's a similar pic:
That inset space on the right is for a washer & dryer (though they seem to have forgotten the dryer vent?). Looks super wide to me. Also note that the stretching affects how long that toilet looks - it's likely a standard bowl but it looks like a very long bowl.
Using the same settings as the previous pair, I un-stretched:
Proportions are better.
The most obvious stretch comes from the kitchen:
If I stretch the outside shot to have the closer to the ratios as kitchen window in the above inside shot here's what the house looks like (this took a 50% stretch):
Unstretched outside shot of kitchen window looks normal:
