Thunderhead



There is not much pure white observable in clouds. If you study them closely you will see they are made up of shades of gray, with a relatively few brilliant highlights of warm, yellowish white. These highlights of reflected sunlight create the illusion that the entire cloud is "whiter" than it actually is.

Another nice cloud study, Tom. I'd be reluctant to try that on such a small scale.
