### HDRI Clean Up

Now we have a high-quality HDRI that perfectly matches the location where our car will be placed in the footage. However, as you can see, there are still some imperfections, such as lens flares, distortion, and the tripod being visible. Since these artifacts can introduce unpredictable effects on our reflections, we’ll need to clean them up.


In the cleaned-up version. We primarily removed the lens flare, the tripod and its shadow, as well as the white car. Since the car was positioned very close to the camera during the shoot, lens distortion made it appear much larger than it should have in the 3D scene. Instead, we’ll use a plane for reflections to ensure a more accurate and controlled result. 

Don’t be afraid to use Photoshop to rough things out, as the most important thing is to ensure smooth reflections.
