Originally posted by cyy47 The JPG is the with Fine setting 2, lanscape color setting with NR medium. In Raw CS4, NR setting really depends on iso. At iso 1600, luminance was 30, color was 25. As the iso goes up, both settings also needs to be increased (at iso 6400, both were at highest
).
In my opinion, the Fine Sharpness 2 setting tends to sharpen noise as well as details.
Here's an example with a 100% crop taken with my K7. The following shot was taken at ISO 3200, shutter speed 1/10, F5, 18mm with my 18-55mm kit lens. Noise reduction turned off completely. No post-processing enabled, this is the jpeg straight from the camera. Custom Image was set to "Portrait" with the Sharpness slider set to its default of 0, just like all the other sliders. This is actually the same shot taken at RAW, but one was turned into a jpeg (by the camera) with Fine Sharpness disabled, and the other with Fine Sharpness 2 enabled.
The image on the left has Fine Sharpness disabled, the one on the right has Fine Sharpness 2 turned on:
Notice how Fine Sharpness 2 has really brought out the noise.
