Why is it still day in Mumbai at 6:47 PM? I captured this news channel picture on Sept 11 2018 from India.



We can clear see It is live telecast from Mumbai, but it is still day time.
This image from https://www.timeanddate.com/sun/india/mumbai shows that daylight ended at 6:44, so 6:47 was three minutes into civil twilight and pretty much close to daylight.

Notice the orange light in the back - I'm assuming that this is a street lamp, which are only turned on at twilight.

Most likely the image appears relatively bright because of camera settings, not because it is full daylight outside.
