Can we enter mobile phone lens and sensor sizes into Vray cameras and match them correctly? or can a tool be made to convert that data into a Vray camera.

Seems to me that I’m always being sent phone camera pictures to work with - would be nice if Vray helped me out with that

I know exactly what you mean

If it’s a decent camera, the exif data should be sufficient to get the required data from. However, yo would also require lens profiles, such as photoshop uses. Plus there is the distortion of the many dodgy mobile phone images. Believe me, I’ve had to do many composite images, using some of the crappiest photos ever. Some as so bad, that even spending an hour with perspective match, it’s far from perfect. Mostly I just spend more time editing the the original photo, than I do in Max haha.

Would be totally amazing, to have a V-Ray camera, that could recognise the countless camera/lens/sensor types etc, just by reading the exif data of a photo, but I have a feeling it would be a very tricky task.. but who knows.. thumbs up for this one though, if indeed it could be implemented.

We just right click the JPG/TIFF/whatever that has been sent through, go to properties/details, check out the camera make/model and google the sensor size for it, then set that as the film gate. It usually gives you a focal length too, which can get you into the right ball-park, even if not exact. It’s not a difficult/laborious process, really?

Unfortunately i don’t think anyone has managed it procedurally.
The best one can do (i consider DxO Labs to be about that) is to rely on a multitude of camera and lens profiles.
Meaning what’s not there puts the user out of luck (f.e. phone, or phone plus cheap clip-on lens.).

You can always use the vrLens utility and create the lens *profile* you want (provided you have access to the hardware, ofc, or they shot the calibration graph for you), to then add it to the v-ray physcam.
