Re: Different exposure when rendering different parts of the image

A month!? That's a very long time. Is this usual for some scene types? That is very long indeed. Keep in mind that most of the sunlight has to go through both the fog and the water where it's refracted and dispersed and bounce around inside the pipe. I mean, interiors can be heavy but I think I've ...

Re: Different exposure when rendering different parts of the image

Have you tried what alpistinho suggested? Reverse gamma correction is just gamma correcting with gamma = 1/2.2. I believe that after reversing the gamma for both sides they will be a multiplication away from each other. So you would need to reverse the gamma for both sides, multiply one of them to ...

Re: Different exposure when rendering different parts of the image

This is right. I would render a preview, adjusting brightness manually in linear tonemapper during rendering and then stop and restart wirh final resolution. Okay, I think you've sort of misunderstood my strategy. I don't want to rerender the full scene since I don't feel like waiting another month...

Re: Different exposure when rendering different parts of the image

Thanks for all the feedback :) I think I've found a solution. There's a little bit of overlap between the halves so I'm thinking that if I render a few pixels within that overlap without gamma correction I should be able to set up a system of equations. I tried without this extra render but then I g...

I'd really like to see it when it's finished.

How would it help to adjust both rather than just one?

Re: Different exposure when rendering different parts of the image

Are you using Auto-Linear tone mapping ? In this case, it auto scales the image luminance and it explains your result. You should have used Linear tone mapping with the same user defined scale for both renderings. Yep, linear with auto brightness :| To merge your already rendered images, it should ...

Different exposure when rendering different parts of the image

My render seems to always crash after about a week of rendering so I decided to split it in two parts. This obviosly solved the problem since I've been able to let it run for more than two weeks without any trouble. However, when I brought the two parts into After Effects for compositing, I realized...
