Image Processing:
- the Maximum Entropy Method deconvolution after composite of the original taking images (the leftmost images)
- Enhanced the leftmost images with the unsharp masking method (center)
- Enhancing the Blue channel layer images with contrast adjustment. of the leftmost images for easy detection of atmospheric phenomena (3rd left) and,hue of the 3images is inverted (the rightmost images ) The Blue haze is shown as yellow
