Another whale tail from our Alaska cruise. This one processed in B&W since the light was so flat that the colors were more a distraction than a contributing element. Nikon D500 + Nikkor 200-500mm/5.6 @ 200mm/6.3, Auto-ISO 500, 1/4,000 second. Shot in Manual mode with Auto-ISO and Matrix metering. Single-point autofocus in Continuous, back button focus. Processed in LR5 and heavily cropped.
