I use Retrolux Showroom https://www.overtake.gg/downloads/retrolux-studio-showroom.25772/
I also disable blur effects so that it's easier to get everything in focus all the time. Finally, I like to use a lot of zoom-in (ctrl +scroll) and to have the camera placed far away to help mimic the types of photos I take of cars on the racetrack. I hoe that helps!
