How to get rid of the "dark borders" (vignettin')?

[Repgahroll]

Hello there

I'm using Blendigo and I'm tryin' to tweak the "vignetting" (dark degradé on borders from centre), but i'm almost giving up... 'cause i tried a lot of camera params and the black border still there...

What is exactly the way to adjust the vignetting?

Thanks.
Sorry m english.

You can't really adjust it, it's an artifact of the rendering process. I believe changing the camera focal length (make it longer) may make a difference, but I'm not sure.

it's not a bug, it's a feature

I know that it isn't a bug, but if the camera aperture is big, the dark borders became unreal... i mean, different types of lens has different types of adjustment or a fixed very light vignetting, but the indigo vignetting is too strong, it should be possible to adjust it.

It's possible to achive perfect vignetting effect using post-render production, but not vice-versa...

I suppose you could have the camera shoot though a transparent material with a radial transparency gradient -- something that's more opaque in the centre than at the edges. This could compensate for the vignetting. You'll have to increase the exposure a bit to compensate for the reduced amount of light reaching the camera.

This isn't an ideal solution, of course. Although the vignetting is physically accurate, it would be nice to be able to turn this off. Hmm... Does using a different camera response function help?

Ono has said in the past that he had already considered making vignetting controllable, I assume he just never had the time.

OK!
Thanks guys!
