I try not to shoot with ISO > 1600 on my 7D, but with 1600 I usually use these settings for denoising: hot pixels: threshold 0.005, strength 1.0 demosaic: color smoothing 3 times denoise (profiled): mode wavelets, strength 1.0, blend mode color (opacity 100%, uniformly) for more noisy pictures I suggest adding second profiled denoise instance with lightness blend mode and playing with strength slider of both. > > On other camera systemes with a different sensor like Pentax, Sony og > Nikon this is a non existing problem. > Canon sensor don't handle noise very well and the raw files is a pain to > process i Dt. > > )-|algeir > > Den 16. des. 2013 10:42, skrev Benjamin Lefaudeux: > > 'Hot pixels' is exactly an 'impulse noise reduction' filter, you can > > lower the threshold if it doesn't fit your needs.
