R5's ISO-Invariance - a happy discovery for shooting Owls at dawn and dusk

Thanks everyone for your input.

Unfortunately, I'm going to have to leave off from this discussion at this point mainly because I'm way out of my technical knowledge comfort zone here.

All I know is that I've been struggling with processing crappy high-ISO raw images of Owls at dawn and dusk from my R5 for the last year and yesterday after either the camera or I screwed up somehow I ended up with an image that was underexposed by almost 5 stops. And when I boosted the Exposure 4.5 stops and the Blacks 50% in Adobe Camera Raw the image turned quite nice.

I think I need to leave it there for now.

Thanks

Thanks for the info, nice to hear about your experience, and others as well.
Technical or not, this is a forum to talk and learn about photography.
Would love to see the pixs, especially before and after.


Thanks Bill.

OK, here are the before and after images.

I did not include the ISO 25,600 image for comparison because after reading all the comments I realize that I did not do a proper control when shooting so the comparison would not be entirely valid. However, it was a pretty poor image and I couldn't make it look good no matter what I tried in post. When I have some time I will try doing a properly controlled comparison between a high ISO shot and the same shot but heavily underexposed and report back to the forum.

Regarding the AFTER image below, there was no processing done to it besides what has been noted. When the image was further processed with Topaz Denoise AI and in Photoshop 2023 it turned out quite nice with good highlights, good colours and a decent dynamic range. Not bad IMO considering it was shot after sunset in a fairly dense forest.

Cheers,
Rudy

Regard the AFTER image there was no processing done besides what is noted, but the image was processed further in Topaz Denoise and Photoshop and turned out quite acceptable with good highlights, good colours and a decent dynamic range.
