Noise issues - Dimage 7i

Well said! I believe this sums up the situation rather precisely.

There is a posting (32 min ago) by Lary Kahn on the 7i noise issue.
Can someone comment on his statment that there appears to be
sigificant less noise when shooting in RAW mode.

Dietmar

what's with this noise issue again?

i look at my pictures in film factory that gives me a full monitor size view, and never see any noise. if i expand the pic to full size, then yes, i see some noise in some of my pictures, but i don't print out 35" wide pics, so it's not an issue.
if you shoot at lower rez, you will reduce noise a lot.

using RAW seems to cut some noise, but not all of it, and again, i only see it when viewing the picture at full size.

as a matter of fact, 2 days ago, i went to my camera shop and took pics with the D7i and the Nikkon D100 that i have on prepaid order, and although it had substantually less noise, it still had noise at full size.

i print pics all the time from my D7i at 8x10 and never see the noise, even though the same pic viewed on the monitor at full size showed noise.

it seems that once a rumor starts, it just never dies..........to those of you who understand what you are looking at, i'm sure you are happy, to those who want to continue fretting over this, then i feel sorry for you........ME, i'm enjoying the hell out of my 7i.

I can't attest to reduced noise at lower resolution, but FWIW I can say that most if not all of us would be hard pressed to see the difference between fine and standard resolution (quality), on screen or print. Only with a glass on an 8 x 10 print am I able to see minute differences.

My point is that for those concerned about noise, processing time, storage space, etc. of the fine quality (2.1 mb) files, you might want to take another look at the standard quality (1.1 mb) option.

Please don't wish for that!! Many of us dislike the loss of detail
caused by the noise reduction algorithm used by cameras like the
707. As I posted previously, I would rather deal with the
occasional noise in an image than lose detail in-camera that can
never, ever be retrieved.

The have been quite a few comments that the 707 sacrifices detail to eliminate noise, yet according to reviews (Phil's, Imaging Resource), the 707 has higher measured resoultion than the D7i? How would you account for that?

I haven't a clue, I'm no kind of expert on interpreting formal test results. I simply know that when I personally look at typical images from the 707 they look (to quote another poster) "plasticy" and artificial. Areas in an image that, in the real world, would have texture have been smoothed out and, to my view, "smeared."

There's no need to "account" for that, it's two completely different things. In fact, an aggresive noise reduction algorithm may increase perceived resolution when using inappropriate measurement tools, such as a lens sharpness chart, since it will smooth out the fine lines making it appear as it has higher sharpness than it does.

The loss is noticed mostly in grainy materials, such as bricks and distant foliage. It's definitely real and easy to see, but to some people it's preferable to noise.
