I've been guilty of buying a filter and then blazing through a bunch of my imagery using the filter I've just paid good money for. At some point, I go back and look through them again and ask myself "why did I make it look that way? Anybody can tell it's a filter"….now I look at the photographs that even seasoned photographers are presenting and it is blatantly obvious that the filter has been used. You know, that "ghost" or "lighter outline" when the filter has done its thing. The people have this glow about them that did not appear when the image was taken. It looks like you poorly masked the person and the edges were of no concern.
Now one could argue the left image has more "pop" but really what is obvious is that something was used to make it pop. I have seen some very fine landscapes by very good photographers where the HDR effect in Black and White was used, and same thing; that obvious glowy edge again when it really wasn't needed.
HDR will give you a "look"; but does everything you do have to have that look??
