- Pick up a high quality IR filter
- Use raw and never exceed ISO 640 [1,2]
- Enjoy 🙂
[1] The M8 ISO electronic amplification changes above ISO 640.
[2] When the light level requires ISO 640, it will be important to maximize exposure. This means you intentionally overexpose unimportant highlights. This improves the IQ in shadow regions. The slower the shutter time and, or the wider the aperture (at IS0 640), the better the shadow regions will look. Should the rendered image looks too dark just increase the global brightness (exposure slider). In low light, when exposure is not maximized (at ISO 640) the symptom is banding in shadow regions. When exposure is maximized, people report you can push IS0 640 raw files by one stop. When all the highlight regions are important, it still pays to maximize exposure. But pushing the brightness during rendering could result in visible banding in shadow regions.
