a stupid way of showing people you know how to take multiple pictures in different exposures. Results of hdr photographs tend to be obnoxious and if not done correctly and professionally they are just plain bad.
Photographer: what are you looking at? its terrible
fauxtogropher: this is my really great hdr photograph, look how bright and blinding it is, doesn't it just give you the best headache? I love using overdone styles in my photography and botching them then tricking people into thinking that I have photographic skill.
Photographer: Poor man, doesn't even know how to take a decent unedited picture. *shakes head and walks away*
