[Pic] 2 Egrets at Cosumnes River Preserve

Thanks all!

The reason you're seeing the grain is because that's only an 800x1200 image. That's not enough pixels for even a 4x5 inch print. On my iMac with a 100 ppi resolution, the image size is about 7x11 inches, so the grain is obvious.

That is exactly why I mentioned denoise. I ran that image though the program just now.

I go to and shoot a ton of concerts for fun. I don't ever have a photo pass and love to shoot from the pit. My shots are never as clean as the ones across the rail since I am only using (most recently) a rx100II like the ones above. Noise is a major problem due to the limited light getting into the high end point and shoot lens.

I sold my sx40 since it was too bulky to bring into the moshpit for most of the shows I attend and got the rx100II since I needed full control over the camera. It really takes great photos.

The Soundgarden photo below was shot on an older canon and it has even more noise due to the limitations of the camera. Lack of control was the reason I move to the SX40.



Without denoise, the image would have been unusable. But I do understand grain. It adds a bit to the grittiness of concert photos but not so much for daylight river photos.

Damn, your concert pics are great, but I don't like the DE Noising of this pic - lots of feather detail was lost in the process.

I used a default in the program for times sake. There is a ton of control in denoise.

Thanks. Got it now. Ended up using http://postimg.org due to the photo sizes.

On second thought, what you're seeing is actually not grain, it's the pixels.

The first eye is an enlargement of the image I posted, and the second is an enlargement of the original image. This is pretty fascinating. This Portra is pretty amazing film. This image was a scan of an ISO 400 or 800 35mm negative.

In any case, like hal mentioned, aggressive noise reduction has a very serious downside. It's a tradeoff with the devil. If you reduce the noise, you lose detail.

weapon, I love those concert photos. You were right down there gettin' the finger and everything.

I understand that the pixel arrangement give the appearance of grain. I know color noise, which I object to but the "noise" in the egret photo gives it "body" in my opinion. I'm not as steeped in the technical details of imagery as you guys so I can only go by how it makes me feel when I view an image.
