I upped the contrast & tone mapped , played with the color & did a graguated tint to brighten the top & did B&W focal to bring the focus up ,croped a little of the B&W area , sharpened the fish eyes and some of the closer fish to create more depth & smoothed the speckels 75 % to clear up the photo . It is a neat photo I enjoyed playing with this one , not the best at photo editing & I used more steps than needed i am sure ,hope you like it .
