I like to establish a baseline understanding of a camera in many ways, performance across the ISO range being one of those areas.
This ISO series evaluates noise from ISO 64 through ISO 25600 using a near-optimal exposure.
- At which ISO does image detail begin to be significantly lost?
- At which ISO do dark areas begin to be too overlaid with noise?
- What is the highest ISO that is acceptable?
Includes images up to 4320 wide from ISO 64 to 25600, and also several large crops at actual pixels from ISO 64 to ISO 25600. RawDigger histogram series from ISO 64 to 25600 reveals interesting quality insights across the ISO range, which dovetail nicely with my subjective findings.
