Look for the Detail tab. You need to scroll down the Processing settings panel to locate it. You will see two sub-sections: Sharpening and Noise Reduction. First critical step: set your view magnification to 100% (or higher; 100% is best). The NR settings will have no visible effect unless mag is 100%. For the kind of noise you get from Pentax bodies I find that the Color control is pretty much useless above its default setting (25). So slide the Luminance slider upwards to suit. Typical values: 20-30 for ISO 200-400 40-50 for ISO 800-1600 Don't overdo it! At 100% you are seriously pixel-peeping so *all* noise looks worse than it will actually appear in a small JPEG or on paper when printed. You should just reduce the noise enough to reduce the clearly visible colour speckles. You may need to experiment once by saving images at different NR settings to see how they look at normal viewing size. NR will tend to dull your image so you'd normally move up to the Sharpening panel after setting NR to recover some sharpness. If you just pull the Amount slider up around 70-100 you'll likely be OK, but I usually also set the Masking level to avoid sharpening the left-over noise in larger flat-colour areas (which makes it worse and more obvious again). Hint: hold down the Option key (Mac) or Alt (PC) while moving the Masking slider and you'll see the masked area dynamically. White areas will have sharpening applied. This will all be much more effective in LR 2.x. If you have LR 1, it works but isn't as powerful. Enjoy! -bmw =========== Wow! Thanks.
