NX30 Noisy Photos?

...whereby folks may have began with perfectly fine images, yet may have destroyed them by aggressive post processing.  The biggest factor here often involves "sharpening."  Some folks are just not aware of what too much sharpening can do and as a result, they feel that an image must look a certain way.  One of the variables I keep in mind when viewing an image is does it lure you into the scene - that is, do you see beyond the "snapshot" and feel what it is you're looking at.  Good images have that quality - that palpable, "you are there" factor.

The problem is that sharpening (over-sharpening, that is) results in the appearance of noise.  And keeping in mind that just about any image (at whatever ISO it was shot at) will have some inherent noise - some noticeable, while others may be imperceptible - can be made to look overly noisy (raggedy for lack of a better description) after too much sharpening is applied.  That's what your image looks like to me.

And sharpening is one area that takes time to fully appreciate.  Oftentimes it's better to "leave an image be," rather than blindly assume that it may need more sharpening.

Then there's the case for in-camera settings.  If you shoot in RAW, then the smartest thing to do is to accomplish your sharpening within the RAW converter (in my case either Lightroom or ACR).  I tend to leave my default sharpening set at 25, but where I assign more clarity is by adjusting the "detail" slider.  For Samsung images, I typically assign a detail setting of 60 - 65.  The key is not to introduce more noise here.  Of course, if you are shooting JPG's then you have to judge what the camera does in this regard.  Some may have to back off a notch with "sharpening" in camera, or increase the NR.

I've always found the NX30 to be a superb instrument, capable of capturing some very detailed images - but like any camera, it's what you do to the images after-the-fact that can result in success (that "wow" factor), or overdoing it (that raggedy or noisy factor).

Just a thought or two here since we're offering suggestions.
