Alright, let me ask you one thing. With your own eyes, do you see a beautiful picture, standing in a shadow of a highriser watching up to the sun lit tower? The one that you'd like to share with others?
My answer is - no, that just strains my eyes.
At the same rate - why do we use flashes when we want to photograph subjects against bright backgrounds? So silly of us. Let's just demand high DR and pull HDR out of our ... single shots.
Or more importantly why in a world people use flashes in such scenarios when they shoot film? Those have sufficient DR.
And the answer is simple - because no matter how much you try to correct the problem, it'll always be better to avoid problem/not make a mistake in the first place.
No one here is arguing about the composition or subject matter of the picture. The picture was chosen to demonstrate a scene with a large dynamic range. Using flash on backlit subjects is typically done, to the best of my knowledge, in order to reduce dynamic range. If you want a picture with reduced dynamic range, go ahead and use fill-flash.
As I understand it, this thread is about preserving dynamic range until the file is output.
