Can you help me how to find this light source?

i have asked a question before what kind of lightning are they using for their interior rendering.
can you please tell me the settings that i need to adjust for this kind of lighting. And what kind of settings do i need to follow as a post rendering for better results

Try to find similar tutorials on youtube on “how to make an interior in Blender” or something like that. I think it’ll be a better way to figure out about light settings that you asked for, rather than searhing for nodes to it

There’s not just one source here, FYI, but it looks like the main one is an HDRI
