after a few test shots of same items, it seems under-exposing 2 stops works with this lighting, lens and Sony camera. The underexposure seems to trigger the grain look at least in that one. It was also iso 1600 whether that makes a difference, it might. Will need a few more tests to replicate it in different light & try other lenses.
edit, the 60mpx of A7r5 makes the Sony worm-noise look more like dots when underexposed at iso 1600 as random shot earlier in that light. the trick I think is downsizing from that, so the wormy Sony noise is not there any more and looks more like film grain which also showed in a couple prints i did. Sony noise is better now imo when you work it. several variables at work it seems, but thanks for asking so could (maybe) figure it out.
later edit/findings after search. Sony worm noise has got better lately per others and what I saw. What I didn't catch was the 61mpx then downsized is the way to get around the noise issue and get film-grain look. Seems to be the trick, uncertain if lower mpx cameras can also do it too like Nex7
A7R5 summary via search makes sense:
- Sony native CMOS noise is now much cleaner.
- Photoshop/Camera RAW 18+ preserves random luminance noise and suppresses blotches → shadows now have a film-like dot pattern, not worms.
- It’s not magic from the sensor alone, it’s sensor + smarter RAW processing.
