Just remapped 5700's CCD.....

After much reading, thought and nail-biting, I just completed what I think was a successful remap of my 5700. I'd like to share the details while they're fresh in my head. Last night I downloaded cpixmap.exe v0.14 from the Russian fellow's sight and tried to run it (after un-zipping of course.) It would not connect to the camera with the way I had hooked it up. I figured that the camera should be on in order to be recognized by the USB. That was the wrong order of things. Connect the (turned off) camera to a USB port (using the little cable supplied by Nikon, THEN turn the camera on. At this point, Windows pops up a "new hardware found" box and asks for drivers. The next part of the struggle was locating the right ".inf" that it wanted. I pointed it to the "trial version" CD of Nikon View and it didn't seem to see what it wanted. After clicking "back" about two dozen times and trying to navigate through every subdirectory on the CD, my computer froze up causing me to re-boot. LOL! This time, I put my "trial version" of Nikon Capture in a CD drive and had another go at it. Camera was already hooked up and switched off. I turned it on and Poof!, the "new hardware found" was back. This time it seemed to find what it was looking for. (Actually loaded two .inf files I believe.) Now, I ran cpixmap.exe and it connected to the camera on the first try! Important side note: Before running the program, the camera must have the proper USB protocol to match your computer's OS. Check page 143 of the 5700's manual for your needs. (Mine was "mass storage".) Anyway, the little program was running and had communicated with my camera! I clicked "read pixels" and watched a bad pixel counter go up while a percent progress counter slowly marched toward 100%. This part took about 5 minutes. It reported exactly 512 bad pixels, the maximum number that the remap table can contain. I read that somewhere, an old thread here, I believe. I held my breath and clicked "REMAP" knowing that I might end up needing to send my baby to Nikon if I muffed it up. There was no turning back. No second chance. The program was remapping my CCD right before my eyes. It was then that my eyes noticed that the battery indicator was now reading half-full. Experience was taught me that by the time the camera thinks the battery is half full, IT'S NEARLY EMPTY. Wouldn't that be a great time for the battery to quit? Half way through a remap? My anxiety didn't last long though. A few seconds later, the program told me that it had finished doing the remap. Nothing left to do now except click the close "X". Time to take some lens-cap-on test shots. My 8 sec shot still contained a few blue and green ones. Nowhere near as bad as the big pink blossom that had been appearing in recent shots even in daylight (ISO 100, 1/500 sec.) My next test shot, two seconds, lens cap on, was COMPLETELY CLEAN! I realize that the longer the camera is on, the warmer the CCD becomes, and the more likely a hot pixel will show up. But for now, I feel like I've done a good thing. Deep breath exhaled.

Does anybody else want to share their remap stories?

WOW very brave of you to do this! Is this only done for " Hot Pixels"? or does it correct anything else? Not so much for my CP5700 but anyone else that might read this? Mine is working great Love this camera! Thanks Dave...............Lamont :> )

Re: Just remapped 5700's CCD.....

congratulations on taking the plunge. I've been too chicken so far. I've got one hot green pixel that's in every shot, at every speed, and so far I've just cloned it out, but its getting annoying. I'm waiting for another hot one to show up before I take the plunge....I can deal with one, but two would be the limit. Actually, I've not read of any cases of someone doing a remap that really screwed up their camera, so each success story is encouraging.

Re: Just remapped 5700's CCD.....

Hello,

I have performed successful CCD remappings on both my dad's and my own 5700. It is no big deal really, the camera has this function built-in already, there is just no way to access it from the menus. I have noticed that Olympus Camedia digicams has remapping as a menu option, too bad that Nikon didn't enable it for us to use.

Regards
Thomas

Hi Dave,

I just did the same thing this afternoon with my 5700. The warnings of the program scared me a little, but I decided to do it anyway. It reported about 450 pixels. After remapping, a lens-cap shot looks very clean. I'm glad I took the risk!

You have no hot pixels? Come on, really?

If you do, try it. Don't be "askeerd"! Have you read of anyone failing (unless they couldn't figure out how to connect their camera to their computer)?

It works like a champ. If I could I'd offer a "money back guarantee" and it's not even my program! After you're done you'll wonder why you didn't do it before! I've done it a couple of times just to play, once while under warranty and then again since the warranty ran out. Zero hot pixels after the remap and only takes about 5 minutes. It's like rebooting your computer, freshens it up. I now look at that program as part of my "Nikon Arsenal"...

Like that crappy tennis shoe company says, "Just do It!"

Would I lie to you? Just remember, at one time I was on the "Most Helpful List"! and the other list, whatever that was...

What do I do? Take an 8 sec photo with the cap on to

see if I have any? So far I havent noticed any in day to day photos. This sort of makes me queasy like when they talk about cleaning the sensors on a dlsr.

At the bottom of this web page is the only tutorial I found to go by. In his example, there were separate remaps of "hot" vs "dead(black)" pixels. In the version I downloaded and ran, there was only "read defective" and "remap." I don't know if I had any dead pixels, it was the big blooming pink one in the middle of every shot that finally made me try the remap.

Harris,

If I wasn't getting that huge pink monster in the middle of almost every shot - even bright sunlit ones at 1/500 sec, I might not have dared to try it. Point of interest: I still have some hot ones in an 8 sec lens cap shot. I accept this as normal. My 2 sec lens cap shot is clean. Can't remember actually ever taking an 8 sec shot, and if I do, I can clean it up in PS. It's the every day shots that were getting intolerable. If your normal shots are clean, then knock on wood and keep shooting. I always went by the old saying, if it ain't broke, don't fix it.

Dave and all,

Yes it may be a little gut wrenching at first, but when you understand what really happens, it's not so bad...

I helped develop the code for the serial support of this program (i.e. SC-EW3 cable with the 990/880): I ran the tool dozens of time on my 990 and a few on my 5700 (still under guarantee by the way!), without any trouble. I would not advocate trying to remap dead (black) pixels and that feature is no longer available in version 0.12 and above.

Here is an explanation of the hot pixels mapping table.
http://forums.dpreview.com/forums/read.asp?forum=1007&message=6108075
http://forums.dpreview.com/forums/read.asp?forum=1007&message=6173449

The horror stories that you read about (camera can only take B&W pictures after failed attempt, etc...) relate to much older versions and with the use of the dead (black) pixels remapping... and since it isn't possible to do that with a recent version, as long as you have a charged battery installed, you should be fine.

HTH,
Philippe

PS: I wish the owner of the page listing instructions (and an explanation in French), at http://www.astrosurf.com/astroscope/tips/pixels_morts.htm would update the instructions to not refer to version 0.04 and would also not indicate to try remapping black (dead) pixels...

I also remapped a few days ago with succes and version 0.12. I did it because a set of green hot pixels on an 1/30 exposure.

I've done a remap on my 5700 yesterday without problems.
I use to have a bright green hot pixel that will show up in pictures
with dark background. Taking a shot with the cap on has also shown
about 5-6 other hot pixels of various colors.

I've first read the defect list from the camera and was a little surprised
to find it was already containing 512 extries in it. Did I bought a 5700
with a "bad" CCD ? I was wondering how many pixels other users
have found on their own camera ?

Anyway, I've remapped the thing and now have clean lens-cap shots.

I have readen something about the table is 512 pixels depth. Each time you make a remap, the program updates the table with let say "the top 512 pixels most hot" detected actually.

I hope this has sense.
