Just 20 minutes waking distance from the city limits, the Santa Monica mountains feel like a jungle. A tiny creek waters lush green grass and ferns, and you can hear birds everywhere. I'm honestly not sure this place still exist, given all the wildfires that have roamed the area since this was shot.
This is a great generic forest HDRI, with plenty of backdrop greenery. Note that the sun light is very spotty, so this should be enhanced with a gobo in front of the key light...
