Hot, Dead, Stuck Pixel Mapping Firmware funciton request to NIKON.

With a bit of luck some kind person will leak Nikons latest pixel mapping software onto the net.

A few years ago the Nikon D100 set up and re mapping software called Q50 Image Adjust got leaked and it enabled me and many others to remap the hot pixels on our D100's.

It takes only a few minutes and is easy to do, I live in hope as I have about four bright Red pixels on my new D300 from Iso 400 up and I will have to send it to Nikon London and loose it for a couple of weeks minimum.

Regards.

Brian.

You are right. I remember that now for the D100. I remember I wanted it to work on my D70 at the time but it wouldn't. I would love if someone would send me the new version of Q50 Image Adjust that works on D700. Nikon could just post it on their support site. Does anyone in Nikon read these forums?

Is this just not a big deal for most of Nikon shooters? I mean, I see what seems a decent amount of folks complaining about this but it seems that there's just not enough overall interest in this feature to start bugging Nikon to add it. If only a few of us complain then they will just blow the complaints off.

Mystifying comments sometimes in these forums ...

Primarily because of lack of interest in this thread. If there was an interest in this thread then I would hope that we could use the interest and maybe get those like Thom Hogan, Moose Peterson to join a petition to ask Nikon for this feature or better yet, maybe a Nikon executive or high-level engineer would finally realize that this is beneficial to both their customers and themselves.

Had Olympus cameras over the past years, the mapping feature works flawlessly.

Do it once a month and you're safe.

All new Oly DSLR cameras I got had some hot pixels - map the sensor once and the problem is gone.

There must be a "deeper" reason why Nikon is ignoring this seemingly simple feature?

Nikon used software on a PC to map the sensors back in the day of the D100. If this software is developed by a 3rd party for Nikon they ought to just sell it for $20 so the ones that want a clean sensor could remap them if they want without having to return cameras to Nikon either to replace or remap sensors and thus save shipping costs for customer and Nikon.

When you shoot JPG in your camera the hot pixels are automatically mapped out. Take a look at your tiff. They are gone.

When you shoot raw in your camera, the Nikon raw converter maps out hot pixels. Again, the new tiff has them mapped out. Adobe Camera Raw does the same thing - as do most raw converters that I am aware of.

I'm interested. And I think Nikon should be too, it would save them a HUGE amount of money.

I returned my first D200 back to the retailer, for too many hot pixels.

I sent my second D200 in for hot pixel mapping at Nikon, this worked a charm, I sent the pixel co-ordinates of the 10 worst pixels and they got rid of all of them.

It's ridiculous that they don't just enable pixel re-mapping in firmware, it would be ideal if the firmware options enabled you to choose how aggressive you want to be in re-mapping, i.e. how stuck the pixel has to be before you want to remap it, because it's not just a binary stuck/not stuck but rather the full 12 or 14bit range of how "stuck" it might be. Some hot pixels are bright white, others are a bit grey, others near black but not quite.

It would also be a great process to do this at the full range of ISO speeds, so the firmware could map differently based on the ISO setting.

The ultimate answer would be to also include temperature into the equation, however, that would require additional hardware, and would be a major pain to actually run the remapping tool as you'd somehow need to heat and then cool the camera through the range of mapping temperatures, so this is of course rather impractical.

TEST:
My D700 has three hot pixels - almost all digital cameras have some.

Using PS CS3 I do NOT see these three hot pixels in my JPG shot (black backdrop shot in studio). Perhaps they were mapped out in camera, or mapped when viewing the JPG (highly unlikely)

Using PS CS3 and a raw version of the shot.

A- I see the three hot pixels in the JPG THUMBNAIL generated in Bridge. That's the enlarged thumbnail which is a JPG generated for viewing purposes as a sidecar version.

B- When I click on the image to see a preview, and before the conversion to tiff, I no longer see the three hot pixels. They have been mapped out - even before conversion to a tiff.

C- The converted raw file - now a tiff - shows no hot pixels.

Others pros have found the same thing. I am not sure what the Nikon software does as I no longer use it. For me, this whole thing is a non-issue. I would need to know more about your choice of software before offering a solution.

Dear Steve ,this time, you are wrong. My experience using D3X suggests the matter of hot-pixels (not dead or stuck ones) is quite complex. Reread my comment on this thread.

Perhaps. However, I was responding to the original OP statement which appeared to address Nikon DSLRs in general and Nikon's need to provide remapping software, built into the camera. And yes, apparently NX-2 does not remap it as ACR and Bridge do. Strange that Adobe does it and Nikon doesn't. Have you tried ACR with 14 bit on your D3x? As all my D700 files are 14 bit I know it works with my D700.

I have NO actual knowledge of the D3x as I don't have it. This is what I know to ne true.

I would whole heartedly welcome some way to go about remapping pixels for both my D3 bodies I just recently purchased. It's quite annoying to have to send them off to Nikon to get them remapped. Sure, I could live with the hot pixels like so many seem to, but little things like hot pixels cause me so much annoyance even if there is software such as ACR that supposedly maps them out automatically.

Yes, one of my D3X has got one dead pixel! strange this, I can see it in raw but when converting it, using NX 2 as a Tiff, the pixel is gone.

This is weird because NX is not supposed to do this but somehow it does or is it just a fluke?

Does anyone here still have that q50?

I would like to try and check if it migh work with my D1H, which I believe is a little older than the D100.

I found a page / blog here which contains a little info about it, and also asked about if he could email me a few days ago.
Still no email from him. Maybe later, he still updates his blog sometimes.

I shoot RAW, then Capture 4.4.2 to 16bit TIFF, then use CS2 to edit, output JPEG for print or web.

Before having it remapped I had hot pixels badly visible at 400ISO and above, even in downsized JPEG images. Ridiculous situtation really. Of course I could clone it out, one picture at a time, but that's a waste of time, especially when the firmware could easily map it out.

Then for long exposure (i.e. 5 minutes) for Astrophotography the hot pixels are a all over the place (probably around 500,000 of them), but there is software that maps it out using dark frame subtraction.

Pentax K20D does it also so, why such a Highly regarded maker deprive their loyal followers such a simple but necessary feature. All sensors will develop stuck/dead/hot pixels over time.You guys should protest to the max,demanding it in a firmware.
