Orca's

We were surveying a proposed pipeline when we came on around 3o Norwegian fishing boats into a huge shoal of fish. we had to slow while we passed. As we passed the closest one that was pulling in its nets there was a pod of 5 or 6 Killer Whales trying feed off the fish spilling out of the net. It looked like they were trying to get the fish that were in the net!
As you can see from the quality the light had gone. ISO was ramped up to 3200 but the shutter speed was still well down at 1/50. with the 500 lens hand held on a moving deck I am surprised I got anything at all.
