It's the part of the process that gives HDR blends those garish shadows and halos. (Okay, flame suit on!)
Not really. Any curve is Tone Mapping (you map tones from source to target. Any Dodge&Burn is tonemapping.
That said tonemapping gets more complicated if you map a high dynamic range image to a lower dynamic range. Curves cannot handle that well enough. There needs to be a local contrast component and this can introduce halos (wanted or not).
Dan Burkholder made amazing photos using extreme tonemapping. This is an ultra grunged photo and sorry I like it .
