The camera and headphones are composited in, pretty sure the skyline is shopped in as well (the shadows on the desk should be much harsher given the bright sky), same with what's on screen. The displays being mirrored for no reason doesn't exactly help sell the reality of it either.

The bookshelf is looking sus too.

I’m not sure if it’s AI so much as a composition of dozens of images stacked on top of each other. The shadows of different objects seem to be going in different directions.

I thought it was 3D.

A further bit of a tangent, but anyway: what really strikes me is the choice of such an image to represent whatever they're trying to convey. It feels bland, and there's a kind of underlying sadness to it... the books, the small sculpture, the shelf, the desk... it all drags me down.

I'm pretty sure the "fakeness" is intentional. The image seems designed to appeal to a specific target audience (when I look at their 'AI erase/replace tool' example I get a clear idea).

For years now all their images have this look, everything sharp at all distances. I enjoy it because it goes against the shallow depth of field trend that has been dominant, it’s refreshing. I think they achieve it by focus stacking, compositing multiple images focused at different distances.

That lens (Sigma Cine 18-35/F2) is a big lens, but it looks almost too big there, like it was composited in, or the perspective is somehow strange.

Ridiculously engineered studio lighting and HDR, I would suppose. Stuff can start looking very artificial when you start bringing in good equipment.

Looks like a rendered scene yes

Softbox lighting and it looks off because obviously no one lights their work desk like they would for a professional photo shoot.
