It's only been since I took up Birding last year that I have had to concern myself with noise. Almost all of my pics are cropped to various degrees. The bigger the crop the worse the noise. I'm certain that my small Micro 4/3 sensor contributes to the problem but I have yet to find a good way of sharpening without adding even more noise. Does anyone have any recommendations/tips/techniques to help me in this regard?
Hi Bert Cropping your pictures to a large size will accentuate any noise. I size mine to about 1000x1000 pixels or less. I save my pictures in the original size but use the smaller size for email, flickr, etc. I find if I go larger the imperfections start to show up. I also don't do a tight crop on a picture I know has a lot of noise.

I can't help with those programs but one way to reduce noise is to separate the bird from the background and just sharpen the bird. If you sharpen the entire picture you will sharpen the noise too making it more pronounced. Then you can reduce noise by running a blur on the background. Mine are 1200 px on the long side.
There is a sharpen tool in Paint Shop pro that's good for sharpening only what you want. You just got over it like a digital paintbrush. That's how I like to make the eyes look pin sharp in my images. I also try to shoot with the highest shutter speed possible in the light I have available so I can use less ISO, which reduces noise. The higher shutter speed will provide a sharper image. Also, using a lens with an image stabilizer or a tripod helps minimize camera shake.
