The Photorealism Mindset: What About The Physical Camera?

Рет қаралды 168,367

Күн бұрын

When talking about photorealism, it’s easy to get fixated on textures and surface imperfections of the objects in our scene.
This talk aims to look beyond this mindset, by shifting the focus to the many limitations of the physical camera. What questions can we ask ourselves as 3D artists, to understand the fourth-wall-breaking consequences of committing to a truly photorealistic scene?

Something that always breaks immersion for me in big budget movies is when there's some impossible camera movement. If there's just no way the camera could physically do what it's doing, then my brain knows it's not real. I feel like his advice here helps to fix that.

That's one of the rules Pixar established in their early days to improve audience suspension of disbelief; always treat the virtual camera as though it were a physical camera in the scene being filmed.

This is why the live-action Ghost in The Shell scenes (like the roof jump from the intro) felt so much more fake than the anime film. The anime purposefully used a tripod shot when we see Major step off the ledge, in order to make the sudden fall feel more dramatic, while the live-action version used a virtual, weightless, floating camera that tracked Major perfectly as she fell, completely robbing any sense of drama from the shot.

As a film industry professional for 20+ years, I can say that he naild it in the video. This is what really makes the difference. If you want photorealism, you need to understand the process behind generating a real image, so then you can apply it to a virtual scene. Great video!

About 15 years ago i worked for a major VFX company and we were making a video for car maker, full animated an rendered but photorealistic. We weren’t satisfied with the camera motion so we build a model of the car in the office (we used chairs boxes, table and some other stuff just to have the position of the wheels the seats an all the other important parts) and took a cheap camera. Whit the camera we filmed the model, tested all the camera moves we needed than we camera-tracked the footage. That made it perfect,because all the little imperfections in the movement made it look real.

It was missing some vibration and shaking. And everyone who has seen dronefootage before knows, that it was fake. The scene itself was missing photorealism too. But this was just a simple demonstration of a really important concept that's often overlooked. A real project would be a little more refinend. Awesome presentation though.

But definately we are overlooking some fundamental concepts of photorealism. Hope one day somebody will find that and really nail photorealism😊

@Windkind0 7 ай бұрын

As a film maker and VFX-person thanks for expressing my absolute pet peeve when it comes to visual effects in Hollywood and elsewhere. They never think about the physicality of the actual camera and the impact it has on the shot. E.g. imagine a film with an absolute flood of zombies - which image feels more jarring: Flying around in rollercoaster-fashion through the zombie horde? Or staying there with the protagonists (whom we're supposed to care about) and watch the horde approaching while the camera slowly dollys in? Now most film directors and DOPs that are currently working on such films grew up with never being able to do expensive crane or helicopter shots, because they were too expensive. But in CG you can do that for free, so they are really tempted to use that just to show off or "add production value". The truth is, that CG works best in nearly all situations if you try to ground everything in the scene (including the camera) in physical reality, as this typically makes it easier for viewers to put themselves into that place. If you want your camera to fly, let it fly, but give me a reason to understand why it is doing that.

Great talk. Pehaps there should be concerns about both things, story telling (Or why the shot?) and also other things, because in this example camera is fine, all realistic movement, but the 3D Itself doesn't look real in my opinion, and this is lacking of photo reference to achieve what a real photo would look like.

Agreed. The talk had nothing to do with photorealism. Was more about gimmicks to improve "believability"/"immersion" rather than photorealism.

@southpaw9041 6 ай бұрын

I wouldn't say it's gimmicks. He demonstrated a fundamental underlying concept that allows you to build your world, logically, from the ground up. Behind all of the high res textures, sharpening, lighting and nice models, the thing that contributes the most to photorealism is a sense of meaning, because in real life people tend to do things for a reason. All of the super nice graphics and colour grading falls apart if your scene lacks authenticity and is not grounded in reality @@MuffFlux

@MuffFlux 6 ай бұрын

@@southpaw9041 "The thing that contributes most to a sense of photorealism is a sense of meaning". That is objectively false. Pixar movies and video games have incredible amounts of "meaning" ascribed to them. It doesn't mean they are photo real. Tell that to the whole industry of commercial/product cgi studios. The iPhone ads with photoreal iPhone renders floating in space, breaking all the laws of physics and lacking camera shake and the other gimmicks. But the iPhone still is photo real photoreal. Same for all kinds of product campaigns. Also gimmicks are quite literally "alter or augment with an extra device or feature". I didn't mean the definition that attributes negative connotations.

14:40 Replicating a low-quality camera feels more realistic than replicating a high-quality camera. It's just like the Uncanny Valley, but for photorealism. Removing or distorting the 3D details for a more realistic view is quite counter-intuitive. But our brain is great for filling up the missing details, so we interpreted the 3D as photorealistic. I think we have our own intuition about photorealism. One person thinks that the detailed 3D scene is photorealistic, but it feels unrealistic for another person. So, finding the common denominator in a 3D scene, such as replicating the low-quality camera (since most people have low-quality cameras on their smartphones), and letting most people fill in the missing details, makes the 3D scene more photorealistic.
