Hi, I textured a sphere with an EXR image for background purposes. In that sphere I placed a physical camera. Now when I move my camera closer to the sphere my render gets darker and if I move the camera backwards my image gets brighter. Of course this is not the result I want. I played with some s…

When you are moving the camera around, I assume you are not moving the center of interest? If so, then turn on the “specify focus” option in the camera and it should be fine. Best regards, Vlado

So did the “specify focus” option help or not? Best regards, Vlado

Yes it did Vlado. Thank you for the help :slight_smile:

We again stumbled accross this problem. Specify focus will not help with this. Specify focus and center of interest result in the same behavior. The closer those get towards the camera the darker the image will be. And you will need the focus point to set the depth of field correctly. This will re…

I can’t imagine why this is expected. When shooting with my still camera the image does not get darker with different focus distance.

Hi Brainspoon, I suppose that you get the effect described in the following topic: - Chaos Forums If the case is different with your setup, it will better to check your scene out, because there could be a bug somewhere in the code.

Right now I would say it is the same affect. But does it really make sense to make it based on the center of interest? Better would be to just have it influenced by focus distance of the camera or the physical camera. In Maya during navigation the center of interest changes all the time and having …

You can always disable either the physical exposure or you can switch the focus calculation to not use the center of interest, but use a fixed value (see the “specify focus distance” attribute).

No I use a standard camera without an “aim”. I just the camera as a whole.
