Nikon D3X Sensor Debris

Nikon D3X Sensor Debris

Had a Nikon D3X handed to me today for a Sensor Clean, and it’s probably one of the dirtiest I have had the pleasure of cleaning to date, the debris was well and truly caked on, this one was not a job for the faint-hearted I have to say! :o)
View Large to see the dirt encountered.
If your not aware of how to check your sensor for dirt/debris then follow the instructions below…

Set your Camera up with an aperture of say f/18, set the lens to manual focus, and shoot a clean white background out of focus, view and magnify all areas of the picture on the Camera LCD or view large on a Computer to see any blemishes on the Sensor.

Depending on Lens Changes and the Environment I have been shooting in, I tend to Clean my Sensor once or twice a year as I’m a bit dust fussy! 😉

Oh and btw, this Camera is for sale, if anyone is interested then let me know and I’ll pass on the owners details.
Thanks to those who look and take the time to comment, it’s very much appreciated.

Dust on Sensor – Canon 350-D – Test/Comparison

Dust on Sensor - Canon 350-D - Test/Comparison

Best Viewed as Original Size

Took a picture of a sunset last night at f/40 for some strange reason and noticed spots on the picture today. First I blamed it on my filthy computer screen but as I dragged the image around the spots stayed stuck! Cleaned my lens… they were still there. So I cleaned the sensor on my Rebel for the first time.

I took some before and after pics just to see if I was making any progress. After I managed to get rid of what I thought was most of the dust, I read that one should open the image in Photoshop and run "Auto Levels". To my dismay I discovered that my sensor was infested with a small dust colony.

Even though my sensor is far from clean it’s cool to see the trusty old blower made a little difference.

D600 : about a thousand shots later

D600 : about a thousand shots later

The sensor’s been cleaned about a month ago, by Nikon themselves (it was totally clean when they sent it back to me, but it took them 3 weeks !). This is the 2649th shot of the camera since I bought it. The sensor’s cleaned by the camera each time it’s turned on and shut off.
I shot a white screen from my computer (cleaned glass).
You can see that the spots are quite at the same place, most of them come from the top left corner, middle left area, and also the same big one at the top, in the middle.
Still no informations from Nikon about this big issue on a 2300 € product.

Then, I’ve read some skeptical people, saying that this probably doesn’t affect pictures in a normal shooting. So I’d like to share one of the pictures that made me wonder about that, because until this particular day, I didn’t care about any "dustgate". I’m not the kind of worried guy about products, I just want it to work properly. Sending it every two weeks of use to Nikon for sensor cleansing, and wait three weeks for that without having my camera, it’s not exactly what I’ve signed for.
This is a daylight picture, untouched jpeg export from the raw file. Info : f/16, ISO 400, 1/100.

All I can say is "filthy". I had been having to clone out spots from time to time under certain conditions of shooting. Today I was hitting those conditions quite often- low apertures, bright light and white backgrounds and it just got to be too much work to clone them out. So I looked for how to spot sensor dust and found this:

Take a longer lens (maybe 100mm), smallest aperture possible (f22 if possible), and open Notepad on your computer (has a white background). Handhold the shot (several seconds likely at f22 and ISO100 (important if you can lock it to that) and make sure focus is set to nearest focus. Make sure the screen is *not* in focus- hold the camera maybe an inch away. The motion from handholding will ensure you are only getting white light in.

After you take the shot, import it into Photoshop and automatically process the levels.

This was the result for me. "Wow" is all I can say. Besides "filthy" that is. I’m gonna have to get this thing cleaned. I’ve been shooting a lot of 3D stock, and this is doubly problematic in that mode, because unless you are very careful with cloning, the clone spots themselves can reveal themselves when viewed in 3D.

I do not see this level of dirt in my images most of the time, but in those certain condition I was seeing dozens of the worst offenders. But that is "dozens" and this is hundreds and hundreds. I had not clue it was *this* bad. Wow.

How dirty is YOUR sensor?

How dirty is YOUR sensor?

This is a test shot taken with my 3-and-a-half year old Canon Rebel XT (EOS 350D) to determine exactly how dirty my sensor is. Lately, I’ve had to do a lot of dust removal in Lightroom or Photoshop, especially when nice blue skies have been involved. This shot is of a sky-blue desktop background on my computer monitor at ƒ/22 to bring all those dust bunnies into focus. Bringing the shot into Photoshop, I ran Auto-Levels on a duplicate of the blue layer to maximise the contrast, circled every bit of dust I could see in red, then turned the duplicate layer off (because it looks better this way).

Terrifying, right? Each of those red circles indicates a dust speck sitting on the sensor array. The two big ones seem to be smears on the lens itself. Read what I did about this sorry state of affairs on my blog. Oh, and view it large!

Cleaning the sensor on my Nikon D70

Cleaning the sensor on my Nikon D70

After years of putting up with dust spots, which show up as ugly grey smudges on photos of nice blue skies, I cleaned the sensor on my Nikon D70. It took quite a few goes as you can see. Each of the photos here is an out-of-focus picture of a blank white computer screen which has then had its contrast increased hugely (by doing "auto contrast" on it) to make the dust spots show up better. The little round spots are dust. The other variations and the larger, slightly dark areas are tiny variations in intensity of the LCD computer monitor which have been exaggerated by the ‘auto contrast" step.

Sensor cleaning – Sony A200

Sensor cleaning - Sony A200

Recently I noticed smudges on my photos and I couldn’t use a diaphragm higher then 6 otherwise the spots would be clearly visible on all photo’s. The auto-cleaning didn’t help a bit. After some googling, I assumed I would have to have the camera cleaned professionally.

Nevertheless, I bought a rocket blower (at a local camera shop for a couple of euros) and after 1 minute of blowing, the result is excellent!!! Almost everything is gone. I’m completely satisfied! These two pictures are taken before and after the cleaning. It’s my computer monitor from up close (out of focus).

I posted these pictures to give an example of how good the result can be with only a rocket blower, because most posts on the internet about this subject are very pessimistic.

Zoom in for more detail. Good luck!

Time to clean my sensor

Time to clean my sensor

I’ve been wondering for a while how dirty the sensor in my Canon 50D might be. After all, it’s been through a lot, including a dip in flood waters and countless frantic lens changes in less than ideal conditions.

So, I took a shot at narrow aperture against a white computer screen, tweaked the levels in photoshop, and got my answer. (The dark streak at the bottom is a piece of hair in the lens, not on the sensor.)

Now, am I game to clean it?

Dusty CCD

Dusty CCD

My CCD sensor before cleaning. Dust and stains all over! It was even dirtier before this shot, these are the stains that I wasn’t able to remove with air.

To see how dirty your sensor is, focus to infinity, set aperture to smallest setting and point your camera at a light even source, eg. a white computer monitor.
