I truly don’t understand the author’s opinions about contrast here. The RE7 image is the only one here that looks ‘realistic’, and at a glance could be mistaken for a photograph, and he says it’s got way too much contrast.

No other image here comes anywhere even close, definitely not Zelda nor GTA5.

Personally I think the whole problem with the first 5 images is that they don’t have enough contrast, and they have too much detail. The color handling isn’t the only reason they don’t look realistic, but making sure every single pixel’s nicely exposed and that nothing gets too dark or too bright is allowing to let all the CG fakeness show through. One of the reasons the RE7 image looks better is you can’t clearly see every single thing in the image.

If you take photographs outside and the sun is in the shot, you will absolutely get some blown out white and some foreground blacks, and that’s realism. The CG here is trying too hard to squeeze all the color into the visible range. To my eyes, it’s too flat and too low contrast, not too high contrast.

> definitely not Zelda nor GTA5.

The zelda screenshot he uses as an example of how good things look without HDR, looks terrible to me. It is all washed out with brightness and bloom, and all the shadows in the landscape that in reality would almolst be black, are very light grey.

For me games being too dark and not being able to see anything is a pet peeve. I can see the point in a horror game, but I will set the gamma or turn up the brightness if it makes the game hard to play.

It looks like a cheap film camera or a home video screenshot. So it gives off a feeling of nostalgia to a sufficiently old person, but this is also the kind of photo you'd reject as a pro, because it's totally overexposed.

One problem with photorealism is a lot of players are on bad displays, or in bad viewing environments. Games often take this into account in their visual direction so that they will be more legible in these different environments. It used to be even worse when designing a game for say the Gameboy Advance or original Nintendo DS where you knew the screen wasn't backlit or wasn't particularly bright so your images needed to be bright and colorful. Even now, a Nintendo Switch game might be played on the bus.

For big budget games the solution for this is typically to have brightness calibration when the game first boots up, but the game itself still needs to be designed adaptively so that it's not Too Dark or Too Bright at critical points, otherwise the playability of the title is jeopardized. This runs counter to a goal of photorealism.

It's not about being realistic but good looking.

You're arguing that game engines should imitate photographic cameras, but they should imitate our eyes, which will never blow out whites outside in the sun.
