Is this CGI or a photo?

Post by Racleborg » Mon Jan 21, 2019 4:34 pm

The sofa in this image looks very real to me, but the room looks a bit CGI. Can anyone tell me whether it's a photo or CGI? (I'm trying to establish how much I need to learn!)

Thanks

If you tried really hard and work on a particular view for long enought you could pull this off probably. But usually it's not very practical and rarely people really need that ultra realism with slightest imperfections.

I believe this is a photo, the cgi-ish look comes from the fact that this is a composite of 1 or more flashes being used to help illuminate the scene properly, so the lighting isn't very natural.

@lacilaci Thank you for your knowledgeable response.

It does look more like a photo(s) to me too, so that's a relief! ;)

I've since been to the site where the're selling the sofa, and when you click on the image, there, an obvious CGI image comes up that has no materials on it. So I guess they take a real photo so show how good the sofa can look, then create a CGI for customers to consider different fabric options.

Thanks again - much appreciated. :)

I agree with lacilaci. There are slight imperfections and usually people don't bother making these for 3D product shots.

Yes I've worked in past for a furniture maker that does this too.
They do a photoshoot of a furniture set up in place and then individual pieces with different colors are done using rendering.

Most of the images in the IKEA catalogues are rendered.
Much more cost effective than building up the furniture and getting it photographed.
Software is VRAY and 3ds Max, for special effects (fire, water, smoke) Phoenix FD for Max.
