Humm, people talk abou a defect in image quality of some cameras and named this "watereffect"...

Is about this defect I'm talking about...

Thanks...

You mean shots like from a phone cam with over processing viz:.

Whilst it is OK for phone cams taking 'snaps' it is a bad idea if you want to enlarge your photos. Generally, the larger the camera's sensor and the more widely spaced the photosites on it, the cleaner (freer of electronic noise and other over-processing artifacts) the image will be. Thus, cramming 12 megapixels onto an APS sensor that was really nice at 6 megapixels can be a recipe for trouble if the in-camera processing algorithms are too aggressive. For that reason only buy cameras with crammed sensors that permit RAW (un processed digital shots) to be recorded. Then it's up to you how far to push the sharpening..

I think you are probably talking about the effect of excessive noise reduction. Small sensors, especially those with high MP, are inherently noisy so some form of noise reduction is essential. But noise reduction algorithms struggle to tell the difference between noise and genuine fine detail, and consequently they remove both. Think of a single leaf in a photograph of a tree. A 10MP image ought to show some subtle detail in the leaf, but noise reduction tends to turn it into a splash of uniform green. Is that what you mean?.

Sorry, I don't have any pictures to illustrate this...

Yes. Its hard to find a compact camera that does not have this effect.I'm buying now a nikon p5100. I hope that is better..

I already tried a canon sd800, samsung l80, and some sonys. They appears that the image is smuged, without details..

My old nikon 880 still looks better...

Sorry didnt understand what your were asking thought you were wondering what a watercolor effect was like in post productionSorrySparky_caI have a photographic memory, but I always seem to have the lens cap on. Current Camera Canon 30D..

Sadly the fact that most compact cams on the market today have in excess of 7mp on tiny sensors means that noise and noise reduction is a big feature of shots at even base ISO. The manufacturers seem to think that noise is inherently bad, whereas I would prefer a grain like noise over a horrible smudging. Also, with no noise reduction you can do your own NR afterwards on a computer with much higher processing power than internally on your camera, or even keep the noise if it is fine (esp for B&W photos)..

Hello. This is an editing effect in photoshop under 'filter' >artistic > watercolor. Here is an original photo and then the watercolor effect:- Will.

Just do a search on the Sony forum for the H9, there were endless threads on it there. Anyway, here is what I found:.

Also, from this thread:.

Http://forums.dpreview.com/...&message=23293627&q=watercolor&qf=mthere is a link to the following gallery:http://picasaweb.google.com/.../merlin1974/RoadAmerica2007VintageRacesSonyH9.

Look at photo 23 (yellow car on the right), photo 24 (red car on the right), and photo 34 (wheel and fender of rear car). Make sure you zoom in on the photos...

As others have stated, the "watercolor" effect is simply heavy NR. All the current crop of small sensor cameras do this to some extent. .

They try to make decisions about WHERE to apply NR and when the little pea-powered brain in the camera screws up, things like grass and leaves start looking flat and "plasticky"..

Here is an example....

I took a RAW pic of a big oak tree. I cropped out a 900 x 600 area in the center of the tree. I applied mild sharpening, because all the pix from my R1 need a bit. Then I applied heavy NR with NoiseWare Pro. Here are the 2 pix:.

It's a subtle but obvious difference. However, NoiseWare Pro is a very sophisticated NR application and is far better than the simple NR found in cheap cameras. To simulate the effect of heavy in-camera NR, I selected a circular 332 px area in the center and applied heavy NR using the "dumb" noise filter in PSE5:.

Yep...that's the "watercolor" effect... .
