Action in low light

So often, you can have great lighting but there is nothing great to photograph. Other times, a fantastic subject is within range but the lighting is not ideal. In this shot of an aggressive display between hippos in Kenya, I liked the diffused light but it was very late in the day and the sun had already set. That meant the light level was very low. In order to use a fast shutter speed so every nuance of the action was rendered with tack sharp clarity, I had to use a fast shutter speed. I wouldn't compromise on that because there's nothing worse in photography than a great capture that is 'almost' sharp. I used a 100-400mm lens for this shot, and my settings were 1/500, f/5.6, and 10,000 ISO. To mitigate the noise, I applied Neat Image software. As you can see, it did a great job.
