I have been spending a lot of time experimenting and learning more about photo editing in Gimp and Picasa photo editing programmes. Below is a sunset cloud shot I took in February .
Above unedited original photo.
The same photo blended with a slightly underexposed photo of the same clouds, quite a dramatic change in the mood of the photo.
Above I opened the blended photo in the Picasa editing programme and edited it on the programmes online "Creative editing kit". Once again a different mood.
