- Panorama X2, MiVue388
I've been trying to look at the useful exposure of the X2 for capturing details and wonder if these findings will help improve the overall settings.
In bright sun, there is burn out and the information is not recorded.
In overcast conditions or low light, exposure is fine, but the shutter speed is too slow, causing motion blur.
In bright conditions, the exposure is too dark, but the shutter speed is fast enough to freeze the image, so at least you can lighten things up to get the information you need via photo edit software.
The conclusion is under exposure is preferable to overexposure and once you drop below too slow a shutter speed, its pointless being correctly exposed if you are looking to pull data (such as a number plate) from the footage.
However this may or may not be overridden by the desire to just record what happens as accurately as possible, rather than "who" did it.
