Is there any life for CCD will CCD affect the quality of picture after sometime of work? may be several years?????
CCD Life?

Welcome to the forum, LD. I think the main thing is more pixels go 'hot' as time goes by (meaning you get extra exposure recorded at some CCD photosites as they age). Raw processors these days are smart enough to throw those out and guess what the value should have been, but if you shoot jpg and your camera doesn't do that it could be an issue.

Related question - has anyone hear experienced excessive pixel failure or had a sensor failure? How many photos on the sensor when it "failed" and how old was the camera? (I'd speculate that age is probably a bigger factor than usage on the sensor for sensor failure. But don't really know that much about that.)

I've had a sensor failure before on a canon and a Sony. The canon (forget model number) just died after about a year. It gave me very strange colors before it completely died. The Sony was a 717. It had a "manufacturer defect" and Sony recalled it to fix the problem. I had the 717 for about 5 years before she showed any symptoms. I got very strange psychedelic colors and strange abstract like images. I was lucky that Sony was still fixing the problem free of charge!
Long after my warranty expired Sony still fixed my beloved 717 including free express shipping both ways. The whole process took about 5 days! And she's still taking pictures for me! I'll try to dig up a photo of what a sensor looks like when it starts to fail. It's actually pretty neat looking :^)
However I haven't had any problems with any other sensor since. My D70 and I know of a few D100s that are still going quite strong!

I have a CCD camera here at work that is on a machine that has been running every day at work since 1988! Granted it isn't nearly as complex as today's sensors, but it takes about 40k exposures a day of parts over the last 21 years shows a CCD has pretty decent life...

Welcome to the forum ldimaging! :^)
The only time I experienced a failing CCD was in one of the school's HP cameras! It was ridiculous! The colors looked infrared, and I was cracking up until I realized that was the last working camera :^(

Unless your sensor is defective I think other parts of the camera will fail first like the battery or shutter. The sensor should normally last many years

CCDs last just as long as CMOSs from what I've seen. If you are considering buying a CCD it would be best to go for a larger system (medium format) as the heating/noise issues are compensated for more effectively. So long as you take care of it and do regular maintenance like any good photographer does it shouldn't have any issues.

Welcome to the forum Izam :^)
I don't think it really matters whether it's a CCD or CMOS sensor. They should both last for many years.

ND - same with my Sony 717. They fixed it years after I got it. Cool psychodelic images for a while there ... then I realized it was the camera that was busted !!

The CCDs on the Cassini spacecraft have shown some longevity. It launched in 1997 and is still taking great photos. I'll bet they wish they had a newer sensor on that spacecraft, though. It has two 1 MP (1024x1024) CCD cameras with 12micron x 12micron photosites. One is wide angle and one is narrow field. State of the art in the '90s. (Kind of sounds like the Ricoh GXR to me.)

Still, that doesn't beat the CCD from '88, PaleRider. Amazing!

Jonny that's D100s as in more than one D100 not D100S as in an upgraded D100. Dang it Nikon please stop using that freakin "S" upgrade designation! It leads to so much confusion!!!!
My wife still has her first digital camera. 4mp HP point and shoot that still works. She was so proud of it when she bought it for something like $400!? I'll see if I can find it. It's in a box somewhere, but I think the drivers to download pictures no longer work or something like that :^(

It only has an internal memory! You have to hook it up to a docking station or something crazy like that in order to download the pictures :^(
Come to think of it maybe she lost the docking station and that's why she doesn't use it anymore.I've been telling her to get a new camera (she's currently using an 8 year old fuji) but she's says, "Why? I can just use one of yours" :^(
Actually she offered to buy me a D800 but I said no???!!!Posted 3 years ago # -
Blast it all! Open it up to see what kind of internal memory it uses—maybe it's readable! ;^)
One time I opened up my Coolpix—my brother and sister where "playing" (aka fighting) with it, and then they dropped it and it popped open at the top. To close it again I unscrewed it all the way and then put it back together. It was pretty interesting getting to look at the inside. I hope I didn't mess anything up though :^(

can somebody help me .recently i notice that pictures from my d 100 are different like more contrast ,poor quality it needs much work in Raw to get something out of it like they are underexposed and fuzzy ,so i dont know if thats just my imagination or ccd has gone to hell. If somebody had similar problems let me know

It could be dead, I mean, the D100 has been out for a while, and if you use it heavily, it may be dead by now.
Best thing to do is to post up a photo.

Sorry, double posted.

Welcome to the forum, cocteau. It could also be your metering system bugging out. What metering mode are you in (M, A, S, P)? You might want to try adding some exposure compensation no matter the mode and see if that fixes the problem. Can you post any example photos?
edit: Should I mention that I always thought my D100 images needed a lot of post-processing? ;-)
Maybe it's time for a D90...Posted 3 years ago # -
Can you post a photo sample of the problem cocteau. A dead or dying sensor will not behave in the manner you described. Like I said before even on an older D100, other parts such as the shutter will die before the sensor.
Post a photo so we can help give you an idea of what might be wrong.

ok i will send some photos but like jonnyapple said it always need post processing ,maybe the problem is in exposure i usually work in manual mode and only in raw files so you can always compensate expo. untill some time i didnt notice that problem i dont know maybe i just not satisfied with d 100 any more :-)
