Thanks everyone for posting your rain photos - they look great! And thanks to everyone for comments
eL eSs Vee - very nice capture - I love the texture and pattern - the wetness makes the colors look saturated.
Corns5 - your flowers are beautiful yellow and I love the waterdrops on the petals.
PatS45 - great abstract - the blue is wonderful. Remindes of a shot I did in my car when it was raining - I just pointed my camera to the sun roof and took a photo.
Whitecapwendy - Fantastic - I love how you capture the ball player with the rain.
Skittledoo - Here are my settings
iso - 400
Post Processing in Photoshop - I did some tonemapping
Also I shot this towards the end of the day when the sun was setting - it really was not cloudy - one of those days when the sun shines and the rain drizzles quickly.
