We made several changes to this picture . Original picture had lack of contrast . First I copy background layer then I change mode of layer called copy background to overlay . It add slightly green to image . In fact I also merged layer then apply color doge mode to layer as I apply oberlay in first step . .It turn blue part of my image into completely white . I took some nice image with huge clouds and cut the cloud’s region in the picture and past into below image . I make use of color balance to add some cyan in the picture .
