Physical Camera - Distortion.

[ruskie77]

Hi all.. any help or thoughts would be appreciated.

 

I'm trying to camera match a still image, and have my camera set up to (near enough) the right settings, except for the lens distortion.

 

I'ts quite a "bulgy" fish eye image, although not over-the top.

 

I cant get a preview of the distortion value in the viewport, (all it seems to do is "zoom" in and out"

VRAT RT (sp2) is giving me a good preview, but without the background image...

 

can anyone suggest how we might get around this?

I prefer to remove lens distortion in photoshop before camera matching in max. I never want the distortion in the final, so why render it into the image.

 

Additionally I believe renderings with camera distortion increases your render time which would be another negative. Although I'll admit that's one feature I haven't played with in a LONG time to know for sure how bad the hit is.

that's a good idea, which I'll try..

 

I'll need to re-add the distortion after in PS, just so that the photo series are all the same.

 

the only bummer is that once you start messing with it in PS, all of your exif data becomes irrelevant..

 

anyone know of an easy work flow for camera matching stills? perhaps a video tutorial anyone can recommend?

 

cheers in advance.

Have you tried out '' guess vertical shift '' in the vray camera option. Sometimes it works out great. RK
