This is from a wedding in the Blue Mountains, near Sydney Australia. The couple requested a backlit rain photo like this so I felt pressure to produce it!! It was only slightly sprinkling, so not the full effect but I'm still happy with this shot - I felt it looked better in black and white in terms of full highlighting the rim of light around them and capturing some of the fine rain drops.
Shot with a Canon 5D MkIV and Canon 16-35 f2.8 with a single Yongnuo YN568EXII behind the couple. 1/160 f2.8 ISO 2000
