WDR level 40% --> 41%
- Thread starter Spirch
- Start date
up to 40 is single flash WDR...
41 and higher are double (on some models even triple) flash WDR...
single flash means that sensor is doing one exposure per frame...
double/tripe means that sensor is doing two/tree exposures per frame, but second one is much shorter that the main one (to catch very bright elements)..
Image processor then combine both frames using WDR algorithm.
this allow to catch very bright elements (like car lights directed into camera) without overexpose the image..
simple (single flash) WDR is always more natural...
full (double flash) WDR is always more digital looking / over sharpen ..

good to know, i was not aware of this
next time it's sunny here i will show what i wish i could do but can't because of that drastic step, not today
yes, WDR algorithms is done in hardware...
So they are developed by SOC manufacturers like HiSilicon (similar to compression engine or image signal processor)...
Dahua/HIK have some abilities to modify "internal parameters" (which we don't see), but as You told the are very different from camera series to camera series...
