>>3445600It's not horrible. You could try adding a radial filter around the cat and lowering the exposure of the environment by maybe 0.2 stops, adding a bit of noise reduction, then loading it into PS, creating a monochrome highpass filter layer with a radius of 1.5 to 2.5 ish (just where you can start seeing some detail but no halos), then taking a big soft brush with 50% gray at 100% opacity, gently painting around the blue area, then taking it down to maybe 60% opacity then painting the green area and just leaving the red area alone, and finally setting the layer to overlay mode. You can spend a bit more time on smoothing out the transition, but basically the noise reduction will smooth out some of the noise around the cat, while the fur and the eyes will gain a bit of sharpness. So even though overall your image is blurrier and therefore less noisy, the viewer still perceives it as sharp.
My battery charger died but if this thread is still up when I get a new one I'll take an ISO 6400 shot for you and try to make it look as good as possible in post to give you a better idea because I'm lonely and I have nobody to talk to about my hobby.
