Ive messed around with my camera and i just dont see a need for anything over 200 my camera is a P&S so maybe thats why? It looks so poor i dont see why its needed.
Can some one post a link or post some examples of images with high ISO? and list the other settings, like shutter speed and Fstop
Oh man, I feel your pain. My A95 is useless at anything over 100. That was one of my beefs with it, & one of the many reasons I let bearmusic goad me into getting a dSLR.
With current technology one of the large differences between P&S digicams and dSLR's is the level of noise at any ISO.. ISO200 is not 'High ISO' as you suggest. The Nikon D70 (And other Nikon dSLR's I assume) have their lowest setting at ISO200..
Doing the winter sports last year I regularly used ISO1600 at F/2.8 to get fast enough shutter speeds to stop the motion, and occasionally went up to ISO3200.
On the 20D ISO1600 is very usable for print media and web work, and ISO3200 looks OK at a push.
Obviously there is some noise, but it's nothing like the noise I used to see with ASA1600 film pushed one stop in the good 'ol days. :-)
that's a nice pic Bazz and impressive lack of noise. i have an *ist DL and the same lens you used for that shot, so you've inspired me to go play with high iso a little more.
Is it the CCD or the hardware that controls the higher ISO? I mean does it take a better quality CCD or somthing to use a higher ISO and still have good quality with litle noise?
I cant believe there is 1600 and 3200 ISO that seems crazy. I mean if i used 400 ISO on my camera it looks like a tv station that has bad reception its so grainy and worthless.
What is the highest ISO available now? i mean is there like a technology race to get to the highest ISO or is there limits? I guess i dont fully understand it all yet.

P & S I think the highest is either 400 or 800. On DSLRs the highest is 3200.
The sensor on a P & S is smaller than a DSLR and the more megapixels that get squeezed onto a small sensor the more noise at higher ISO. Generally speaking that is.

This pic is not totally void of noise it is there in the shadow areas. Look under her chin. You most likely will not see noise in bright highlights or near blacks.

It's all about the money.
Sony and Nikon have worked on the latest group of high pixel packed sensors and their noise levels for the amount of pixels per micron of space is mindboggling. Nose levels as low as what CMOS snesors with twice the size just a year or two ago.
Canon has the D20 and it has an impressive amount of pixels per micron of sensor space and very low noise as well.
There is only a finite amount of real estate under those 35mm lenses and their corresponding imaging areas. All DSLR's will gravitate to the same amount of pixels per micron in a few years and Noise levels will be comparable.
Also, the electronics/compression software have a major effect on noise at high iso. Look at the Canon 5D and the Nikon D200. Without special attention to the electronics both cameras have had instance of banding at High Iso. Even the Canon 1D had the old double sided banding a few years ago.
But look at the Canon 1Ds Mark II and the Nikon D2x! That tech is going to be in all cameras soon and its pretty freaking sweet.

I printed the color version for my wife as an 8x10 and it looks even cleaner.

I agree and I think it will still be a number of years before we see noise free ISO3200 but it is still useable as of now.
I could've cleaned it up a bit with NI but it was an outake for the "Noise" challenge. I actually wanted a lot more noise and my score for the challenge says the voters did too :) Now it just serves to represent an ISO3200 shot without noise reduction.
I too never really saw the need to shoot with high ISO. That is until I started working at the school newspaper. Now I find myself using it all the time. I'm usually stuck indoors in some horrible lighting condition and flash often looks horrible, so high ISO is there to save the day. In sports especially I often wish I had 3200. With point and shoots its not really an issue because of quality but with some experiene with a d-slr, I'm sure you'd be using it sometime. Here's a couple of shots at 1600.
