Originally posted by stacylynn Sometimes I'll take shoots in ISO 3200. Then I will go and take photos of something else and forget the camera is set at 3200. I think the grain looks awful, I was the one in my college photography class that complained we used 400 speed film rather than 100. Is there a way in on the computer, in Photoshop, the Pentax software, or another software to reduce this noise?
Most of the Raw workflow programs have some sort of noise reduction feature. I believe that Bibble Pro uses Noise Ninja, which you can also get a separate license for. Adobe Lightroom has its own noise reduction sliders that work pretty well.
But you should be aware that noise reduction after the fact is like almost every other form of post-processing: you're better off if you don't have to do it. If the noise is really bad, no software can really fix it. And it's possible to tell when a picture has been run through noise reduction the same way you can tell when someone's had a face lift: everything looks unnaturally smooth. In my opinion, it's sometimes better to leave the noise alone and see if you can get people to accept it as artistic. I try to fix the noise only when it's not very bad to start with.
