How to correctly set photomatch camera with real exif ?

andybot · 5 Nov 2014, 23:36

When I finally corectly matched my model with inserted photo in SU, I can´t set my camera with the same parameters as picture was shooted.
When I use on photomatch scene a tool "Creates a physycal camere with real world camera parameters", I'll see that focal lenght should be 26mm but when I use it in VRay camera setting, my render looks different than in viewport...

any distortions in photomatch won't be matched by vray. One thing you can try is to click on the zoom tool. Then look at the focal length value in the VCB (box at the bottom right of your SU window) click in that box and type in the exact same number. You may see the camera "jump" slightly, with the photomatch distortion being removed. Then save your new view and try rendering again.

That's odd, do you have a model to share?

That's been a problem forever. Have you not encountered it?

Not sure if this matters or not, but the Advanced Camera tool output on the first image is set to Screen, have you tried setting it to Photography > Full Frame (or APS-C depending on what type of camera took the image).

This is maybe misunderstanding becouse of my english.. .)
There are some distortions which I saw by modeling the room from photomatch - I do not care about (its not so big problem).
My problem is that: I can see correctly matched model as I want in scene but I can´t render it in the same view as I see in viewport..

Please see following link to my SU model:

Hi, I have tried it but it didn´t help - as attached
Photo was tooked by Digital Canon 7D which isn´t fullframe

I also tried to uncheck override settings and to have only advanced camera - the result is quite simmilar as in viewport but still it doesn´t match with enviroment/matched photo..

I do not know if I understood correctly - I typed the same number from VCB box as the new override FOV and notting jumped..
When I tried to render it still isn´t correct.
