Nikon Z6 - Admirable Dynamic Range Performance


Hi everyone, this blog will focus a little more on the Z6's dynamic range performance at high to higher ISOs.

This time the main subject was Singapore's cityscape during blue hour which is between 7:30pm to about 7:45pm (of course weather dependent)

SETUP DETAILS

Nikkor Z 24-70mm F4.0/S

AUTO ISO

RAW

Hand-Held

f8.0

1/160s

Image INTENTIONALLY captured with approx. a 3 stops underexposure

ISO3600 Image with exposure recovered from 3 stops underexposure

NO noise reduction

NO sharpening

The 3 stops underexposed RAW cityscape capture

The Exposure Recovered image - NO noise reduction - NO sharpening

The following shows the series of 400% magnified screenshots of the ISO3600 Exposure Recovered image to show

- Shadow Recovery Details

- Highlights Details

- Grain after exposure recovery

- If there were any presense of Banding ?

FINDINGS

- Grain a little higher then expected but normal to me after a 3 stops underexposure recovery

- Good that the the grain is consistent with no abnormal colored pixels

- Great news - NO banding that I could see after a 3 stops underexposure recovery for this scene

- Shadow details excellent

- Highlight details superb , look at those Bank Building Signboards

- Overall a pretty AMAZING performance in my books

- Grain seen from exposure recovery can easily be fixed in post production

ISO9000 Image Performance

ISO9000 RAW Image with exposure recovered from about a 1.5 stops underexposure NOT as severe as the ISO3600 example above

NO noise reduction

NO sharpening

The following shows the series of 400% magnified screenshots of the ISO9000 Exposure Recovered image to show

- Shadow Recovery Details

- Highlights Details

- Grain after exposure recovery

- If there were any presense of Banding ?

FINDINGS

- Overall another pretty AMAZING performance in my books

- Image quality very close to the ISO3600 image with 3 stops underexposure recovery

- Great news - NO banding that I could see at all

- Highlight details just a tad weaker that the ISO3600 version but still excellent - Compare the image with "Bank of America Merrill Lynch" sign

- Shadow details excellent

- Grain again is consistent & very similar to the worst case ISO3600 version

FINAL COMMENTARY

- Complete confidence with the Z6's dynamic range performance at the extreme high ISOs

- Details resolved by the sensor & Nikkor Z 24-70mm S lens is excellent - no complaints here

- Happy that I did not see banding even with a 3 stops underexposure in the shadow areas

- It's clear that performance at the extreme ISOs will be spectacular with good exposure control when capturing the scene

Till the next blog , Happy Holidays !

Cheers,

Andrew
