Dark and not so much light in green channel due to the light source. This is without a tone curve applied.

Thanks for looking into it! Is there a reason that his face looks so grainy at ISO 1600 though? Should I have went up to 3000 or higher since it was so dark? I usually underexpose and then fix everything in post but this RAW is so noisy to start with.

R6 is "ISOless" from ISO 1600. Using the same exposure at ISO 1600 + 1 EV in post or same exposure at ISO 3200 should give you the same noise. Feel free to try at home. You can try ISO 1600 + 2 EV in post vs ISO 6400 also.

I would say that the cuprit is the light source (LED?)

Oh interesting! Did you see photo 1? That one is a lot more close up and shot at 2500 ISO, but her face is super noisy along with the background behind her. You think the issue is just the venue's lighting and not anything mechanical with the camera or the settings on my end? My 5D Mark IV seems to have handled low light better which shouldn't be the case, right?

I saw all three from R6. Have you compared R6 vs 5D IV with same exposure and same motive?

No tone curve applied in the print screen above.

Yes, it is noisy, but that is due to exposure (not enough light) and the quality of the light.

With the profile FineDetails that I tried to copy from DPP4 to darktable.

I can't see anything wrong with your camera. It looks like my R6. If you want less noise I recommend DxO PureRAW. If you don't have it I can send you those three sample files.

Hi Peter! Thanks for all your advice! I'd love to see the samples with DxO PureRAW. I'm looking into the program now and I'm very intrigued.

One thing to consider for the future is a wider aperture lens. While it would not have the flexibility of a zoom, an 85mm f/1.2L lens would do quite well. Even at f/1.4, that would be letting in four times more light than your f/2.8 lens. So you could reduce ISO by 2 stops (e.g. 6400 down to 1600).

The distance to your subject should be far enough away so that the shallow depth of field shouldn't be an issue.

Sent you a PM with the files.

Sorry I'm late to the thread but I downloaded your shots and then had to run to an appointment.

Anyway, I opened them all in DPP 4 and they look pretty clean using it, even with the lighting conditions and zooming to 400%.

Here are a couple of jpg's zoomed to 100%, which are pretty small in width. All I did was adjust white balance. Other than that, it was in and out using DPP's "Convert and save" command. I did have to d/l your lens profile, but I let DPP adjust that (I used it's defaults) and the same with NR.

100% zoom.100% zoom.

I ran this one through Topaz Sharpen because it has a tendency to reveal noise (using a very light setting). The only thing I saw were some hot pixels, which I've found to be common with my R cameras.

100% zoom - Topaz Sharpen AI.

As you can see, these are pretty clean and typical of my R5, R6 cameras. Now, my R6 mark II takes it another notch 🙂
