I am looking for an apartment in eastern Europe. I was shocked to see listings with the windows covered in Microsoft Paint. I was able to find the location in some instances by finding the same property in other listings (the images were still slightly altered). This is the amateur move, what I see more often is image alteration so that the light coming through the windows makes it impossible to see what is outside. The same apartment is usually posted by 5-10 agencies, pictures and description almost identical, with different location. You get different responses depending who you call. I hope to end my suffering this year and buy something.
Oh it is definitely possible to avoid this. It's kind of an arms race. The overexposed window effect might be reversed with computational photography for example. Maybe one can just lower brightness in an image editor and discover that there is a residual of the outside left. You might use "looking around a corner" like tricks on white walls, etc etc.
