that does fix the issue. However there are several problems with this change.
1. It hides a commonly used checkbox behind an unintuitive series of clicks.
2. The save setting is not available in the camera tag.
3. It is possible to add two stacks of the 'photographic exposure' checkbox that apparently conflict with each other.
4. the right click help function common throughout C4D is not respected. Right click help does not provide documentation on the functionality or changes to this feature.
