OTOY Forums

With all the great car renders that have been posted, I thought I'd give it a try. This is not my own model - I think it's from Dosch Design. Getting the materials right is tricky so I definitely need to work on that in the future, but none the less, this is definitely the best car render I've ever produced, IMHO.
It was rendered at twice the resolution and scaled down in Photoshop. Fireflies were removed with that clever little Defly app No post other than that.

Thanks for looking

it's a good first attempt
the only thing is that it looks like a little model instead of a car.

Radiance

Thanks

You're right - it does look small. I wonder why that is - maybe the DOF is too strong. I also used a lot of vignetting because I like that effect
Are there any useful ground rules to follow with car visualizations? Or do you just keep tweaking till it looks right?

One thing you should try remember while training is that a strong dof is not a real term at all. Most people think that the words "strong dof" is a shallow dof with only a small part in focus. This is false.

Dof is the area in focus. So alot of dof means alot is in focus and a small dof is macro shots.

You need to add real life scale to the scene, that is what truly lacks. So what is real life scale? Well that is something that tells tou that the car aint microscopic or giant. Right now there is only a car and nothing else. Your ground has no texture thus its not possible to determin scale. Same goes for the background. Make textures and props that puts the car in relief.

"Strong DOF effect" is perfectly normal term, even among photographers. It refers to wide open aperture (small F-Stop number, shortening shutter speed)

Actually "Small dof is macro shots" is your made up terminology and it doesn't make sense at all !

When people say too strong DOF for short (I am one of those who do too) it's usually to point out it's complete unnecessary-ness is such pictures. People just basically over-use it since it's so easy to play with it here, but it ends up out of place for most of the time.

Dof is whats in focus. Lots of dof, lots of stuff in focus.

"Are there any useful ground rules ?"

Yes there are First, no simple flat plane, unless you want to model highway or parking place, have backplate matching your HDRi, use simple studio setup, ie. basic half-U-shape, like in photo studios, erasing your horizon line.

Interesting HRDi will make for nice reflections too.

No, I answered this.

"In optics, particularly as it relates to film and photography, the depth of field (DOF) is the portion of a scene that appears acceptably sharp in the image"
This is what you refer to, and also the "shallow/deep" part terminology.

I mentioned none of that. I simply explained how it changes meaning when people have in mind the whole "DOF effect (stress on latter word)" simply shortcutting it into "Dof". "Strong DOF (effect) " doesn't correspond to neither shallow nor deep.

Ok, let's lay it off. This is pointless off-topic argument. I know that you know what DOF is, but at same time, I know you can see it's wrong in most of the pictures. Post(send) them this link.

Oh c'mon, I am not such illiterate I've read it, no worry...
