I was reading about this yesterday, very interesting, thanks for posting this tip.
Does it apply to all, D3, D3X and D3S?
I was reading about the D3S and how it compares with the D3, when I spotted an article on 'thermal issues' (white dots) with the D810, curiosity got the better of me so I read the article below:
https://nikonrumors.com/2014/08/22/how-to-tell-if-a-nikon-d810-camera-has-the-thermal-issue-fix.aspx/
It seems there is a firmware update for the D810 which isn't directly available for public download, which fixes the D810 issue. I wonder if there is a similar fix for the D3 and it's derivatives?
I also wonder did the firmware number change when you did the procedure?
Have you updated the firmware?
My understanding is that all sensors have dead and 'hot' pixels. (A bit like all hard drives have some 'bad sectors'.) During manufacture the dead and hot pixels are mapped out so they don't appear in the image. Perhaps the procedure you describe 're-maps' those dead and hot pixels which have developed since manufacture?
I have to say I haven't noticed any hot pixels in my D3 images, the amount of night photography I do I would have expected to notice some if they were present.
Robert,
I read that article about the D810 , do not know what that is all about , tho`I have heard that there are ..hot / stuck / dead pixels and now Thermal issues too..What`s next , Chemical emulsions with grain instead of pixels...
Indeed , this way the camera " maps out " those dead pixels just like the factory does, the firmware I have for D3s is A 1.02...B 1.02 and D3X is A 1.01 and B 1.02 ... which is the Latest I believe ..
Tho` I Doubt it has anything to do with the Firmware , as I just did the same " trick " with my Kodak DCS Pro SlrN , did that twice ( anything has to be done twice with the SlrN ).
Two pink dots remained , Only noticeable under X-treme Magnification.
I develop D1 / D1X /D3S / D3X in Capture NX-D ( I love that freebee )..
SlrN developed in Kodak Photodesk ( another freebee ) ,but that is all for RAW output, and those Programs will take care of Any pixels , as You and J K have noticed with PS , LR etc.
So all this " mapping " was meant to Improve on J-pegs , and there it works like a charm.
I did not mean to cause any confusion , so just to be clear , all is Well in RAW.
