My pleasure, and if you leads you to start finding ways of getting results you like even more than what you have already been achieving, then great!

BTW, one aspect pf this discussion *is* actually relevant to the subject of shooting high ISO, and that has to do with the perception of noise as a function ofhow prominent the noisy area is. In concert photography, it is pretty common for the musician and instrument to be illuminated, and most of the rest of the scene to be in shadow. Noise in the area we don't care about is problematic in that it can form a distration from the areas we do care about, but luckily, this is often solved easily by pushing the shadows (where much of the noise is) darker, thus compressing their dynamic range and thereby lessening the noise within those areas. A curve that darkens everything from midtones down can be a great NR tool, and then you can be more judicious about the NR you apply to the parts of pictures you don't want affected so much by NR artifacts.

A little high ISO....

Sometimes our dwarf cat Shiela really gets annoyed with the camera. This was one of those moments

Those kitten photos are great.so much detail.

I agree about the BW trumpet player photo, plus you lose the warm reds.

Amazing! At first I thought you had typed in an extra zero in the ISO!

Glade you like them.

You know, when I looked at the numbers at first.. I though they were 1600 and 2000 too. And I usually prefer to work in whole increments when it comes to ISO, but in this case, I let the camera choose(priority shutter), and these were the numbers that came out of it(kinds funny).

That cat is a real treat!
She's very small, but chalked full of attitude.
Were very happy to have her. And take pictures of her when she allows it.

FTR. the images were shot in RAW, processed in ACR w/Topaz Denoise for NR. - I usually give my high ISO images a quick pass in focal blade to raise detail, but neither of these required any special processing or attention.

All these cats... I feel the need to even things out a little

I'm not sure why I shot this at such a high ISO - I suspect it was because I had been previously trying to capture the dog leaping about on the boulders.

Jack, ISO 2500 - K7

K2000 + Kit Lens DA-L

Just got this camera back after someone "borrowed" it for 6 months, lesson learned is not to loan out cameras and such to newbies or wannabes. This is one of the 1st shots after I got it working properly.

ISO3200 which is tops for a K2000...

ihasa and theunartist -

Great to see the K7 and the K2000 perform well in this group. Seems like they have fallen off the radar which is a shame. Great shot and wonderful cameras.

ISO 5000 shot is remarkably clean. Great shot of the moth, nice capture
