I was photographing a wedding. whilst the bride, groom and guests sat for the meal, i went outside of the venue into the garden area, i took 2 photos, one straight after the other of the garden area, it was a cloudy overcast evening. when i uploaded the photos i noticed lights etc in one of the photos and not the other which had been taken a fraction of a second straight after. this may be lens flair however when i zoomed into one of the lights, similar to a triangle, it appears to be a solid object. i of course don’t know this for sure and like i have said, it may well be lens flair but i am sending you both photos for your attention.
