The previous post ended with a question from Patti asking about noise when using high ISO and shadow recovery.
I can honestly say that the noise is not that bad.
Here’s a before and after photo. (On Left) ISO 500 and very unexposed. (On Right) Basic processing with shadow slider moved to +88 and exposure slider moved to +1.25.
Below the photo is enlarged to 100% and cropped. I moved the exposure slider a bit more and then hit it with a bit of noise reduction in Adobe Camera Raw.
The noise doesn’t look too bad despite high ISO and pulling the exposure.
The Canon R5 files are pretty amazing.

I just posted on your first article. Check it out, hoping the link works–it’s to a low rez Facebook version.
But, as I shoot astro, I’m not finding the noise much less than my 5D IV… but, if and when the $ allows, I’ll get an R6 or Ra, as one is astro specific, and the other is a tad better, according to some, which makes sense, as its pixel pitch is better.

I’ve liked the R5 and R6 for astro. Both are as good as the 5D IV in my opinion. Thanks for posting and my apologies for the delay in replying. I didn’t put all the buttons on my reply.

Also, your image above is impressive, as it is processed from an underexposed image, which I also seem to do a lot. I’ve been gunshy about “Exposing to the right”, as I’m often shooting high dyn range images, and hate to have washed out highlights. Like in the old days when I shot slide film 98% of the time, underexposing was safer.
Upon reading/viewing some good material, I’m trying ISO’s of 6400-12800 for astro…and it is better. Plus, I’m about to learn how to star stack. I have been shooting the differently exposed images (diff settings as well) so I will have plenty of material to work with.
