A shot from lap 18 out of 20 from rF2 Asia Series Formula Renault Series.
Using the Live Weather plugin and update from weatherundergound.com and following local time, it rained all 2 hrs and 45 minutes when the sun was higher. But there was an occasional cloud openings amidst the cover and with the low sun in Jiading.
The lighting on a few of those shots above look very good. I had to check if this was the "edited" screenshot thread. Very natural and soft. Like an overcast day should.
