K20D Noise

I must be doing something wrong. I've seen very good images at ISO 3200, but I can't seem to get as good results. Here are some illustrations with and without NR in Lightroom. Am I expecting too much?

K20D, DA* 50-135 f/2.8, 55mm, 1/250 @ f/6.7, ISO 3200.

Full Frame.

Actually, for being dark, I would say that's about normal.

It seems to be more or less normal. It is rather easy to remove it in post processing. I guess at least in part the good results you are referring to could be attributed to good image editing. Secondly, I have noticed rather large differences in shadow noise among various raw converters I have tested.

WOW! Gas is $1.69/gal!

Photos look pretty good to me for ISO 3200 too.

Actually, I'm pretty impressed (makes me feel better since I've got a K20D on the way - to be delivered 12/25 - AM). This looks better than what I've been able to get out of a K10D at ISO 1600.

Around here, 1.69 is looking pretty high - for "regular". I saw 1.41/9 today for 87 octane here in SE Texas; unfortunately, both of my cars require premium, but that's dropping too. My wife, who's car happily burns 87, is gloating.

Looks like my E-330 at ISO 400. Great if you ask me.

That seems to be about right for 3200.


Gas (Petrol) in Aus is about $1.10 per litre as I write... and I thought that was cheap

Steve, have you ever compared the output of your K10D and K20D at ISO 1600?

Try real NR software

Hello!

Like the others said, the K20D has great potential regarding noise, but good post-processing-skills are necessary to really make use of it. The donation-ware RawTherapee for examples delivers little bit lower noise and foremost a finer grain. But even if you use Lightroom, the integrated noise reduction is just horrible. A genuine NR program can do much better. I've added a version of your image run through NeatImage.

Original:


Lightroom NR:


Neat Image NR:


I think it shows less noise and noise pattern than the original, but cleary more detail and a finer texture than Lightroom's noise reduction. You should try it. Mastering a good NR program gives you about two stops of usable ISO range.

I wish my K10D shot that well at ISO 1600, although I'm embracing luminance noise as if it were film grain.
