Bug report: Exposure effect > Gamma Correction control is broken
The Exposure effect in the latest version gives a different result with the same exposure values as before. For example, in my project I have the Exposure effect with the Exposure value set to 3. If I open the project in the latest AE version it looks so much brighter. To get the same look in CC 2014, I have to set the Exposure value to 15 instead of 3.
I found that the Gamma Correction slider in the Exposure effect behave inconsistently with the previous versions of AE. If the Exposure value is set to 0 and you drag the Gamma Correction slider down it looks like everything is working as it should. But once you increase the Exposure value, Gamma Correction is broken. I try to lower the Gamma Correction value, but the color values increase dramatically for some reason. In my case Gamma Correction was set to 0.2 and that ruins everything. That makes no sense, it looks like a bug!
- I see this inconsistent behavior in the 32-bit project.
- I use the latest vesrion of AE (16.1.0, build 204).
- The NVidia driver is updated to the latest version.
- I tried both, CPU and GPU rendering with the same result.
Thank you for filing this bug report. Please see the comment from Jason Bartell below: this bug was fixed in the October 2018 release of After Effects (version 16.0; note that the current release is 16.1.1). You can install this release via the Creative Cloud desktop application.

Thank you for reporting this. There was a bug with 32-bpc projects and the Exposure effect with the offset set to zero. This was fixed in AE 16.0. If you set the offset to something small, like 0.0001, I think you will find the Exposure rendering matches across versions. Also, note that your screen shots show Gamma Correction set to 0.20 which effectively makes the Exposure setting much more sensitive so that is contributing to the strong over-brights there.
