Can high rez mode be used for stationary nude models?

Will it work here?

Tripod Hi Rez is super finnicky about movement, there is no subject alignment so any movement pretty much ruins the image. Hand Held Hi Rez is much more forgiving and will compensate for some minor subject (or camera) movement. I'd opt for the HHHR ..... if I got the chance.

Probably not unless they are wax :-) However, there has been some improvement since the E-M5 II when Olympus originally implemented Hi Res. I took Hi Res then at the same local park of the same waterfalls and the images produced had disgusting cross-hatch patterns. Years later, yesterday, I happened to try tripod HR with my recently purchased E-M1 III and saw none of the cross-hatch abomination.

Here's a link to it in case you are interested. It is on my OneDrive but DPRevived doesn't seem to accept the URL. Plenty of motion but no nude models.

Not wholly applicable to people photography but it does show me that some improvements have been made with moving subjects since Hi Res was first introduced.

Yeah, I've done some like that but it is very difficult. Pretty much have to be on a tripod, use continuous light, the model has to be in a very stable position and hold their breath while shooting. Really not worth it, in my experience.

IIRC, DPReview's reviews of the Panasonic 35mm-format cameras indicated they were better than most at compensating for subject movement. That said, I have no experience with this.

I think that mostly applies to movements you might encounter in city scapes or landscapes where the movements are taking up a small part of the frame. A tree swaying, are pedestrian walking, etc. Not sure if the same applies for subjects that are taking up the bulk of the frame. 🤔

CHCl3

FWIW: CHCl3 = chemical formula of Trichloromethane (aka Chloroform).
