I set my upper to 25,600 on my Z8. It’s quite noisy but without having fast glass it’s a good compromise for me. I will use Photo AI in some of those situations. Sometimes I don’t bother and use other techniques in Capture One. It all depends on the image. Sometimes I’ll have an image where I can mask the background and do some noise reduction and lower the luminance curve. That can sometimes fix a lot. I’m also not super picky. I’m do this entirely fit my amusement and I’m willing to make various compromises when needed.
