My camera, overall, did pretty well with noise reduction. Very few details were lost, especially at ISO 3200, but it did make the image slightly soft which isn't something that we want. There's almost no difference for the three modes at ISO 100, because there isn't really any noise to remove in the first place. Some detail is lost on high when shooting at ISO 800, but it is minimal. Standard noise reduction overall gave the best results, because it removed a sufficient amount of noise without loss of detail. Although in-camera noise reduction works, I won't use it, just to avoid any possible loss of sharpness. I can always remove noise in post-processing afterwards.
