diode Posted July 14, 2014 Share #1 Posted July 14, 2014 Advertisement (gone after registration) Hey everyone! I've had my M for 6 months now and I've noticed that on certain shots I'll get groups of faint little hot pixels. (in random areas all over the shots mostly in transitions between shadows) It appears most between iso 640-1000. It's pretty faint, but once I push the image too far they really appear. Anyone else get this? Is this normal noise or this a sign I should send it in? Thanks! -Alan Welcome, dear visitor!

mjh Posted July 14, 2014 Share #3 Posted July 14, 2014 Noise, yes, but hot pixels? I don’t think so. Link to post Share on other sites More sharing options...
Dannybuoy Posted July 14, 2014 Share #4 Posted July 14, 2014 Simple solution - Don't push the images too far ;-) Link to post Share on other sites More sharing options...
diode Posted July 15, 2014 Author Share #5 Posted July 15, 2014 Thanks guys! I'm a pixel peeper and I was just curious if that's how the M handles noise... from your comments, yes it is. Link to post Share on other sites More sharing options...
John Black Posted July 15, 2014 Share #6 Posted July 15, 2014 Increasing the chroma (color) and luminosity noise reduction in your raw editor of choice can help reduce the grain. On high-ISO shots I usually process two variants - one with moderate noise reduction and no sharpening for the defocused and shadow areas, and a second version with less noise reduction for the in focus areas. Then blend the two layers in photoshop (erasing parts of one layer to reveal the layer beneath). Merge, edit at will and then apply NIK noise reduction on a second layer for the defocused areas. Yes, it takes time, but ISO 3200 can come across looking surprising clean with little loss in details. Once all the editing is done, sometimes I add a little grain back to smoothed areas to makes the whole edit look more cohesive. If the ultimate destination is printing, printing hides noise extremely well. On screen viewing reveals the noise much more (IMO). Link to post Share on other sites More sharing options...
