Hi CCC,

That is quite an AWESOME cloud!! Looks like I wouldn't want to get too close to that.

It may be my monitor, but the image seems to have a slight blue cast to it. You may want to do a white-balance check on it (if you have software that can do it). Choose a white selection in the cloud and make sure that it is color neutral (RGB values all about the same).

Cheers,
Tim
