Attaining the most natural look with the p510
I leave the sharpening setting in my P510 to it's default.
I find that in post processing, I still need a small amount of sharpening.
It does produce images that are a little over-saturated.
The digital zoom with this camera surprises me, but it is still noisy. I gleaned from other posts that the only time I might want it on is when I am in movie mode.
I would be tempted to use the high setting for noise removal in-camera, however I am using the normal setting.
Auto white balance is not perfect but it is a lot better than Canon's.
Some of the artifacts that I see are a result of the bokeh in the image, the arttifacts are not always there. This implies that the number of aperture blades in the lens is not adequate for all situations.
Wherever you can limit iso to 200 or less, it will be fairly clean in good light.
That said, I have had to clean up noise in iso 100 images that should not need to be cleaned up, but the noise is there. This does not seem apparent in good light.
