Danke und was wird da bestätigt?
Downsampled Z 9 images (to 5568 pixels on long axis) vs. full-resolution D6 images:
• Up to ISO 5000: No difference in visible noise. Yes, that's "up to ISO 5000".
• ISO 6400: Slightly less than a 1/3 stop advantage to the D6. This means an ISO 6400 image shot with the D6 has slightly more visible noise than a downsampled ISO 5000 image shot with the Z 9.
• ISO 12800: Approximately 1/3 stop advantage to the D6. This means an ISO 12800 image shot with the D6 has about the same amount of visible noise as a downsampled ISO 10000 image shot with the Z 9.
My comments: OK...at least to me this is VERY interesting. To be clear, this means that while a D6 still wins in delivering less visible noise at high ISO's compared to downsampled Z 9 images, it doesn't "win" by much at all (only 1/3 stop at ISO 12800). This makes ME wonder if there is really any value (beyond nostalgia!) in keeping even my D6 for those "very high ISO moments". I honestly did not expect the downsampled Z 9 files to be this competitive with D6 files.
1/3 Blende wird man in der Praxis am fertig entwickelten Foto nicht mehr erkennen können. Also genau das, was ich hier die ganze Zeit versuche zu erklären. Es gibt bei gleicher Ausgabegröße quasi keinen Unterschied.
