Hi people-drama,
I'm uncertain if there is an option with light. I would need to see a file that perhaps is reduced to the problem.
Could you please look at these options, if anything could be helpful?
This will work if the image of the background is set to Emission and placed on a large sphere.
I instead look at a file and explore it than guess. Please use via Dropbox, Wetransfer, Google, Adobe, or Apple cloud services, downloadable.(Please, no rar files.)
Perhaps think about compositing.
Cheers
