Rose is in the Water, Jack is dead but still with her, and 5th Officer Lowe is searching for survivors in the water. After the lifeboat has passed Rose and continues on its way but before she gets the whistle, watch for a stern shot of the lifeboat. Watch as the flashlights are searching ahead of the boat. In the upper right hand corner you can see the edge of the tank (or pool). The light hits the water and the edge of the pool, and although the same color, you can see a line where they meet, and the light from the flashlight "bends".
