Do not fill this in!==How it works== The script allows the camera to enable/disable the built-in ND filter according to the current light level. It then sets the shutter speed to <u>Target Tv96</u>, and adjusts the Sv96 (ISO) to achieve a correct exposure taking into account any exposure compensation. This works much like a shutter-priority mode. If a correct exposure cannot be obtained due to over-exposure even at <u>Minimum Sv96</u>, the shutter speed is increased until a correct exposure can be achieved. This will result in a shutter speed faster than <u>Target Tv96</u> if it is particularly bright. If a correct exposure cannot be obtained due to under-exposure even at <u>Maximum Sv96</u>, the shutter speed is decreased until a correct exposure can be achieved. This will result in a shutter speed slower than <u>Target Tv96</u> if light levels are low, but has the advantage of creating some nice light trails when driving through tunnels etc. The exposure is recalculated prior to each shot to allow for changing lighting conditions.
