Hi
I made some testing during the night and yes, the WDR takes three frames and join in one, during the day no problem as the shutter speed is very high and the result is very good, during the night it is a problem as the shutter speed is around 1/60 to be able to give 30 fps, with 1/90 and movement the imagen is blurry but static is no problem.
This is two images blurry one over the other, without WDR it is also blurry, but you dont have two exposures and then you don't have a double image. (blurry but not triple?).
I have to make more tests because I am not sure if the camera will go below 1/90 to 1/30 to get more light, but then we will have also a blurry image but not 3 of them on top of each other. Not clear if you can read better the plate numbers.
What is clear is that during the day with WDR it is better, you don't have to post-process and there is less noise, artefacts and blocks in the shadows.
In any case, if you don't use WDR you will need to set anyways EV -1.0 front and EV -0.3 rear, if not you will lose the highlights that can not be recovered.
Please post your experience.
edit: I have tested several EV and yes, you can get almost the same result in the front camera (not but near) but in the rear camera WDR is far away better than NO WDR, it is impossible to be close. Let see tonight, then depends a lot how much you drive during the night. During the day the clear winner is WDR.
