>>3544961First off, you are confusing what dynamic range is and there is so much wrong with this post I can't even begin to address all the flaws. You have really triggered my autism.
its called dynamic RANGE. its a measure of the RANGE a camera can record between brightest and darkest parts of the image. The amount of light is not a problem. You can do a 1 hour exposure during the day and get millions of times the amount of light and you will not get better dynamic range.
