Spectrum Vision True WDR" substitutes a snappy term for actual info about the specs

For decades, higher end cameras have included WDR, but they normally tell you what WDR quality level you're buying.

What is WDR?

For decades, higher end cameras have included WDR. WDR takes a low light optimized and a high light optimized image setting and stitches the two photos into one image to prevent shadows from being too dark. The industry standard way of describing WDR is to state whether it is digital or True/optical (with true/optical WDR being better since optical WDR also still has digital WDR). The industry standard way is to describe the WDR spec is to state the dB that the true/optical WDR uses, with higher dB ratings being better.

Wide Dynamic Range

What's a dB?

The dB unit is the ratio of the brightest and the dimmest object that can be captured by the camera. This tells you the range where the WDR works. The higher the ratio, the greater the difference between the low light and high light spectrum that the camera can capture and the better your picture will be. This is why high dB ratios are better - they can capture a larger spectrum of lighting conditions.

What is Spectrum Vision WDR?

They don't list the dB ratings, so no one can know. Do different models that claim to have Spectrum Vision all have the same results? Is one model better than another? How do they compare to other WDR products?

You can't know what Spectrum Vision WDR even is, since they aren't telling you anything about the actual specs.
