The best thing about rainy days is the soft lighting. The thing I don't like about rainy days is the color temperature.
By just winking a flash into the model's face I am able to keep the soft light and get a better color for skin tones. The other thing is I can open up the eyes a bit and put a little catch light in the eyes as well.
Here are some more examples of using the off camera flash:
The other cool thing about the overcast cloud day is you can use flash and panning so much easier, because the light isn't so bright. When it is sunny in the middle of the day it is almost impossible to get your shutter speed down below 1/250.
In the photo of the young lady walking I am dragging the shutter to 1/6 at an ISO 100 setting. The flash helps to freeze her and then the rest of the photo is blurred. I like this motion in the photo. Helps communicate she is on the move.
