I'm pretty sure he said they were coding their own lighting from the ground up instead of relying on HDR.

Im an amateur photographer myself and even though I enjoy hdr in some pictures it is almost always overdone.It wouldnt add much to the realism of the game so Im with Oleg there

We've seen HDR shots in the past so I expect it will be used as part of the lighting engine, but yes Oleg mentioned he prefers a more subtle approach and wants to avoid the usually exaggerated way it's done in most games. Let's hope it works out like that.

(not trying to knock Rise of Flight here btw, they've done some beautiful stuff with their engine, but the HDR part seems to produce too many surreal images for my taste)

If you want to see some horrible HDR, go play the original Brothers in Arms. It seemed that everyone's skin produced light instead of absorbing and reflecting it. Sort of like how people portray angels in movies. Glowing skin with light blooms all around them. Now days they've toned it down quite a bit, but I think that Oleg probably has a better system that that "cut and paste" effect.

Yes I remember how after the Lost Coast tech demo for Half Life 2 (which was actually quite well done) many developers went crazy with HDR & bloom. Results were often unbearable, but they could at least claim to use the latest and greatest technology. And for many people that seems to count more than the actual result.

Heliocon you are absolutely right, it's a travesty beyond proportion.

I would suggest you make a real stand and not buy the game on principal.

You can use the time you save to g00gle up an education on the graphics features you are getting yourself so worked up over.

But whatever you do please dont stop posting your little nuggets of wisdom, sport!

For the record: an image with a lot of contrast and dark areas is not a HDR picture. The opposite is true, an HDR image shows details in all areas, with reduced contrast.

In photo: Several exposures can be combined into one, each exposed perfectly for certain parts of the photo, and themn merged so you see detail in sky (not overexposed) and shadow (usually dark).

Please stop saying the bottom photo of the two submitted earlier has a HDR.

Never said that.
HDR mimics the way the eye perceives lighting and details. You obviously didnt put much time into thinking about it. For example if you are in a dark room and walk out the door into bright daylight, it temporarily blinds you (for atleast a few seconds). Your eyes adjust and you are then able to see details etc. This is the same mechanic as a camera's exposure, which is the length of time light is let into the lens/film etc. Same mechanic with the eye, except its not based on an "exposure time" but based on the quantity of light that enters through your pupil. I am not a photographer but I certainly have enough experience with film, so if you want to throw crap my way make sure you think it through.
@Roy: He didnt nail much, HDR in games is completely different than HDR in photography. Seriously, dont say he nailed it because it makes you look stupid, when was the last time you say a print or a picture emiting light? Not often, but a monitor does. In basic theory its the same "physical mechanic" which is based on light and the eyes perception of said light, in practice photography and graphics engines are very different in nature.

Also HDR is an effect that can be toned down if they want to, but eliminating it is silly.

Did I mention hdr IN A GAME??I look stupid??You need to calm down my friend.You got a right to defend your ideas but that is not the way.You do the same on every thread,who do you think looks stupid??I said he nailed the description of HDR I didnt say inside a game.I got a tip for you, whenever your angry start counting from 1-10 very slowly then reply. This forum is so full of whine.
