- Cropped the sky area using the Magic Wand Tool.
- Copied the sky from any of stock photos.
- Duplicated the layer to create cloud refelections in the water.
- Erase some part of it - Opacity 20% in the water and 100% in some other areas, i.e. boats and structures.
Just a little different version of a great image.
Levels adjusted to make the sunny parts of the mount more bright, filters to add a little drama, radial blur and reframing.
Hope you find it useful:)
