Steve does a quick comparison with the Nokia Lumia 1020, one on Amber, the other on Lumia Black. In daytime, performances are pretty much the same but in low light, there are some slight changes.
The performance improvements lie in how the software chooses exposure, which made the video much darker than it could be.
Video capture under Nokia Black seems to use a higher ISO per video frame, resulting in higher digital noise but a brighter image to the viewer. Note in the street footage that the caravan across the road isn’t even visible in the Amber video footage but can be seen clearly with Black.
Steve notes that he is using two different models of 1020s from different continents but he doesn’t think that should cause an issue. Well, as long as they’re roughly the same age batch. If you remember before, Marc from PVC had a replacement over his first batch 1020, and the newer one was significantly better.
