Duh, what was I thinking? I meant to say Shutter.
So with the P3S the exposure is adjusted two ways; shutter and ISO. The ISO (International Standardization Organization) indicates the light sensitivity of the camera.The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The component within your camera that can change sensitivity is called “image sensor.”
100 is as low as you can go and is pretty much the default for outdoors. From there everything doubles; 100, 200, 400, 800, 1600, 3200, 6400. For nighttime video, you will need to go higher. 3200 is about the top of the range though some cameras can go to 6400.
Here are some screen shots that may help. You can open the menu under the red record button and then adjust everything from there. I would play with the shutter speed first then ISO. The faster the shutter speed, the less light will get in. 25 is as slow as you can get I think. You can refer to the EV (Evaluation) Meter at the bottom for more guidance.
If all else fails, try AUTO!
