What A Little Moonlight Can Do. The almost full Worm Moon over La Mesa, California on March 27, 2021. This was photographed with a circular polarizer and then I put my hand in front of the top third of the lens so that the moon wasn't overexposed. No editing in Photoshop or Lightroom required. #WormMoon #WormMoon2021 #moonlight #LaMesa #SanDiego #FullMoon
