Beautiful cloud photos

Awe-inspiring photos of the late-afternoon sky from Emma Davis, who adds some great photography notes: There were lots of really cool looking clouds today, must be from the storms blowing through. The two dark sunset photos were taken at sunset as the sun was disappearing behind the next wave of storm clouds. To deal with the overwhelming brightness of the sun and preserve cloud detail, I used a really short exposure and a variable density filter. The clouds had this wonderful rainbow fringe effect around them – red-yellow-green-blue. I think it must be because they are heavily laden with moisture and the water droplets were refracting the light. This effect was much more visible (more greens and blues) in person, but the short exposure and the filters heavily emphasized the red end of the spectrum.
