Am I the only one that hates the HDR and DOF? I'm not trolling since I'll probably get it for 360 if I get it but it hurts my eyes following everything on screen.
You certainly can have your opinion, but for the sake of argument, they (and loads of other developers) have been trying to imitate typical optical effects or all those effects that basically mimick our limits as human beings due to the way our eyes are made. They also try to mimick some the "limits" (to me they're not limits...) of our photography technology at the same time.
HDR simulates how we react to different lighting conditions and contrast, and if done right, it looks VERY realistc especially compared to non-HDR computer graphics which looks "flat" by comparison.
Depth of Field effects also target another "limitation" our eyes have, which is basically our inability to focus on more than a certain depth in space at any one time, and to be honest it has become somewhat of a last-year-status-symbol in games, and therefore overused in the same way "lens flare" and "water effects" and lots of other effects have enjoyed throughout the years when they first were introduced to realtime (and also non-realtime) graphics.
The problem with DOF is that in real life, WE decide what's on focus and what isn't, and that's a decision that is made on what we are looking at and focusing on at any one time, whereas in games (and movies or pictures too!) that decision is not ours, it's the director's decision. In these cases it's the director's choice on what you should look at, taking away the naturality of it. That is why it can look a bit out of place, and coupled with the fact that it's vastly overused most times, then i can understand why some people don't like it.
In this case, if in real life you were reloading your gun, you'd have to look at it even for that one second, and in real life, when you look at your hands, everything else further than your hands looks blurred (heck, it actually looks blurred and doubled, so you're lucky that they stopped at the "blurry" part ). It's natural and the COD devs probably wanted to replicate that detail. I think it looks cool.
At the end of the day, if they're done right, not overused and not made "the cool thing" about a game, these effects (and lots more) can look amazing.
Remember, the culprit is not the effect, here who's guilty is the developer who abuses this effect to create a novelty WOW effect, without thinking that maybe that could affect gameplay, when he could just turn it down a notch or two and make things look easier on the gamer.
That's my take on this anyway...
