This is a retouched picture, which means that it has been digitally altered from its original version. Modifications: Extensive post-processing based on a JPEG source (no Raw available): adjusted brightness, contrast, and tonal values; applied noise reduction and sharpening; selectively enhanced weak blue tones in the water surface using blending modes to emphasize sky reflection; some retouching to reduce image artifacts and surface imperfections. Modifications made by Radomianin.
