The turtles were swimming in a shady area while the croc was lying in a sunny place. To save highlights, the capture was underexposed a stop. In post, brightening up the shadows produced some noise level of 10 which were left alone as that didn’t seem to be too intrusive at this size.
This was shot through a glass screen that was rather dirty near the water level. I came away with an image that was completely hazy. In post, the dark and mid-tones were darkened to remove the haze and this had nicely darkened away the background as well. The water had also need of being separately darkened further.
