I often spend time photographing the changes in the clouds near sunset or sunrise. The low sun picks them out nicely and on a windy day they can change amazingly fast, creating interesting patterns and shapes. Since I live on a hill, the back of my house offers quite a nice view over the roof tops and sunsets can offer a real "silver lining" to most days (see what I did there?).
In these dynamics I try to plot the changes in shape of the clouds against one another using various digital blending techniques. At some points the clouds appear like liquid.. while at others the changes in the clouds shape are very clear.. This is just one example of many dynamics I created from this session, the vertical lines mark out the edges of some of the images.
