Gerald Undone has published a video on his Youtube channel in which he shows how he was able to measure almost 14 f-stops of dynamic range with the new iPhone 15 Pro in an IMATEST setup.
The whole thing worked "only" with the new Blackmagic app, while in other apps an automatic dynamic range optimization from Apple accesses, which can not be easily turned off.
The native ISO (the range at which the sensor showed the greatest dynamic range in the measurements) was 1480 ISO. However, Gerald and his team also achieved the corresponding dynamic range only with the appropriate denoising in post-production:
On the one hand, this is not necessarily unusual, since almost every camera nowadays uses internal noise reduction to increase its dynamic range. After all, the lower limit of dynamic range is always noise, and that's why the dynamic range inevitably increases, as long as the noise reduction is actually set effectively.
The fact that the signal is downsampled from 8K to 4K can also contribute to a dynamic range gain, since noise is also averaged out of the signal.
Dennoch liegt die Pixelgröße der zusammengelegten Sensel noch deutlich unter dem Wert, mit dem übliche Cine-Kameras 14 Blendenstufen Dynamik erreichen. Hat Apple also hier die Physik überlistet oder sind hier "Computational Tricks" am Werk?
Noch wissen wir es nicht, aber wir werden hierzu in Kürze ebenfalls Hinweise liefern können.
Danke an Axel für den Hinweis
