This thread is dedicated to all those that place caps on their 'usable ISO range'. I thought I would create a thread for photographers to place their before and after high ISO images in a bit to inspire those that don't use their camera to it's potential.

I'll start off and welcome everyone else's input.

ISO12800 (D7000)

Before & after.

What was most remarkable about this to me was that it was shot after dark and the illumination was street lighting. How the camera managed to make all those colours out of yeuchy yellow street lighting I have no idea. And thanks to the guys at Canon who engineered the modern marvel of IS exposure was hand held 1/8sec at f4.5 35mm on my Canon 15-85 EF-s

Only PP was to remove the luminance noise in LR4 (but did start with +1ev exposure)

I'm sure there is a much better image in there somewhere but I was on my way home form work with not time to linger :-(

There is no value in these examples for noise reduction.. for changing the colours maybe.. but at these sizes it seems useless unless these are 100% crops which I doubt but you dont say ?

At 100% it will still be noisy as a subject - can't do much about that. It's about trying to salvage the image, which is where the skill comes in and of course as an image, no serious viewer looks at 100%.

Viewing at 100% is for sharpness & focus testing.

you have started a thread with the title noise reduction.. then you show us an original so reduced in size that there is no noise.. then show us an edited one equaly no noise but different colours... how can we see how you have altered the noise if you dont show us any noise..

you posted the thread to tell us it was about noise reduction then posted before and after pics so small we couldnt see any noise :)
 
Hold the headlines, groundbreaking news "noise reduction software works" :notworthy:

What ISO/body was that shot at Dave? Looks pretty good as an original have to say...
