I normally do not do noise reduction as it will cause loss in details, contrally I will sharpen and crop a bit which may cause noise to be more obvious
Here is one at iso 1600 which hardly any noise at all
Probably will try some at iso 10000 over the coming weekend :think:
now that just makes me feel a little sad abt my k-x. haha i guess this is just one of the many reasons the k5 cost more than 2x more!
