Image Pixelation / Noise

I've notice image pixelation and more noise in my images when shooting at ISO ranging from 100-400 with my 1Ds MKII. The body is fairly in excellent shape with a bit over 70k actuation. My image results no longer look at clear in color, noise, and pixels as it did when the camera was new. I'm not sure what's happening, but I've never seen this behavior from my camera in the past. This behavior is sporadic which cause image quality to fluctuate when viewing them on my CPU screen. Out of 100 images shot under the same lighting condition in M mode and the same setting, many of them will look pixelated with noise vs others looking closer to normal. The following now happens before using DPP and after using DPP to reduce file size, the image quality gets even worst. Please note: I only shoot in RAW format.

What's even more strange is that: I recently viewed old images stored many years that were crystal clear in color, pixels, and noise and now they look faded as describe above. How is this possible? Has anyone experience this issue with their 1Ds MKII body or any canon digital camera body?

Questions:

1. Is it possible the 1Ds MKII image sensor is worn and needs replacement?

2. Is it possible my CPU monitor is fading? CPU and monitor is less than 3 years old.

3. Is it possible my CPU video card is going bad?

4. If the 1Ds MKII sensor needs replacement, how much will it cost today for repair?

Are you using non-native resolution on an LCD monitor? That would be a problem, and would result in goofy pixels.

I am getting this same problem with my 40D- 70/200usm is 2.8L. I've no idea how many actuations I have but would bet it is way over 25K.

Here are a couple examples. Note that I have tried to clean these up in PS by smoothing them and noise reduction. I will host a couple raw unedited shots if that will help.

That tells me right there that the camera isn't the problem, and since a digital file won't degrade in quality, with the exception of possible file corruption, I am suspecting a monitor problem or possibly something happened with the colour profiles on your system.

Here's a thought, does your picture difference look kind of like this?(With now being the top and bottom being before)

Both of those look fine to me.

Can you post a sample photo or two? I would guess it's something with your monitor or color profile settings if you're seeing the same issue with older images that were fine before.

I would look at your display and the software. Images do not change over time.

Did your screen resolution change? Does your viewing software use the highest quality resampling? "Nearest Neighbor" or "Pixel Resize" or any number of various names for the same thing work by simply dropping entire rows and columns of pixels, and leaves you the remainder. the results are jagged, and noisy. Your use of the word "faded" seems contradictory, though.

ImRaptor,

You photo example is done quite well. My images use to look like the image at the bottom of the screen, but now, they look a little better than the image you posted atop. Either way, I'm sure something is not right with my image results when I view them on my CPU monitor. When viewing them from my LCD screen, everything looks fine and perfect to my standard. If it's a monitor issue, I don't know what could have caused this because I have not changed my monitor or settings for many years. Also, I did not change from the most recent version of DPP, so I'm SOL when it comes to fixing this issue. Any suggestion how to adjust the monitor. It's a Dell 24" LCD monitor and the resolutions are set to the highest 1900 x 1200 and the Hz is set the highest as well. I've given up on fixing this issue. I need some help. I will try to post pictures soon if I can figure out how to post them. Thanks to everyone!

What the cause of my differing pictures was colour profile. One program could handle it and one couldn't.
The same picture in different programs looked worlds different, the difference being that one could manage to read the file properly and one couldn't.
Try opening the pictures using a different program than you normally would.
Check out this thread https://photography-on-the.net/forum/showthre​ad.php?t=296149
for a better description on colour profiles and what programs are colour managed.

"Both of those look fine to me".

And to me.

Ah, hang on, I do see some artifacting either side of your logo in one of the images?
