Cleaning the image sensor

Having recently purchased a second hand 300-D I have noticed 3 faint spots on all my images and decided I needed to clean the image sensor. The manual directs me to Menu 2 where there should be a 'sensor clean' tab however on my camera it is non existant....any suggestions?

Re: Cleaning the image sensor

Check with your local Camera store first or the makers website before you get handy. A very soft and fine make up brush may come in handy But check it our first

Recently I found one balck spot on my picture, I dont know whay the black spot is coming. I am having a Nikkon D90 18-105 lens.

The black spot can be from one or two sources. The first, is a called a stuck or hot pixel. Your camera's sensor has 12.9 million pixels (12.3 million are used for the image). Many times, a hot or stuck pixel is a bright color - red, yellow, green, etc. It can be any color however. Dark or black pixels can also be called dead pixels as they look like they're "off." Regardless of which your camera suffers, it will not respond to light projected on the sensor by the lens. You'll have to have manually edit the pixel in each image, or return to Nikon for sensor replacement. Nikon used to perform a mapping out of the pixel, but it seems that they don't do this any longer. A sensor replacement can cost in the hundreds of dollars.

The second source, is dust on the sensor. A pixel(s) blocked by dust will show up in each picture, but will appear to be more in focus in some images than others - depending on the aperture value of the camera when the exposure was made. A stuck pixel usually has a very definite edge on all images regardless of aperture setting. A simple, careful wet cleaning of the sensor with a product designed specifically for the job can solve this problem pretty quickly.

Here's a video for wet sensor cleaning from Youtube There are others here too. I hope this was helpful & good luck!

Usually such screen flickering occurs when you had applied some pressure on the LCD ( can be due to high shocks on the camera such as dropping it from a height, hitting on the LCD ...etc ) and will eventually damage the screen.But it wont affect the pictures you are taking since the image capture is by the inbuilt image sensor.You can claim for the warranty if it's a manufacturing defect and they will service it free of cost.Your valuable feedback would be appreciated.

I am not sure whether this feedback will work for me or not but still I must say that I am totally dissatisfy with canon DSLR camera and it?s service that is available in Kolkata. 16 months ago I bought...

Believe it or not, most cameras come with "factory dust" just waiting to float onto your sensor. Cleaning it is quite easy with the right tools. Google the words..."cleaning a DSLR sensor" and you will find numerous sites that will explain the procedure with pictures and they will list places to obtain the equipment (which is not expensive and once you have it, you can clean your sensor anytime you need to).

I have a Canon SD780IS camera and now notice dark spots on the pictures. I tried cleaning the front of the lens with a Q-tip but they did not go away or move around. I have 2 such cameras . One with 6-8...

to thansen 3:
Yes, eventually everyone who owns this camera will see these dust orbs in every photo they take once the problem appears, and the problem continues to worsen until you will see no image at all. I've had my SD780IS for about 2 years. I was very proud of what this camera could do until the dust appeared and discovered there seems to be no do-it-yourself solution. Canon will "fix" this under warranty.
When Canon returns your camera, it will no longer take sharp photos, but the dust orbs will be gone..... for a little while. Soon, we will all tire of sending these crappy, expensive little cameras back and forth to Canon. All of us will eventually toss this expensive junk and find another expensive Canon to use for about one year before we toss that one too.
The spots appear due to the complex external lens assembly which by its very function (moving in and out) invites particulate invasion. Canon deliberately allows us no recourse for practical maintenance outside of never using the camera. Why didn't I consider this before I purchased? Well, I trusted a corporation whose mission I thought was to provide durable high quality product. The plastic disposable film cameras of yore were an honest version of what we have purchased here.
You may notice a tiny hole on the ring surrounding the lens. My guess is the Canon techs insert a $.25 tool here which with some certain push and twist of the fingers will pop the lens assembly, exposing the CCD and rear lens element for cleaning. Effective reassembly may be another matter altogether as proven by the less sharp images I experienced upon return of the SD780IS from Canon. I have yet to locate any good solution addressing this difficulty. However, my wife still likes this camera despite her 20/950 vision. Some people are very easy to please. When she notices the spots, I'll look into getting her another camera.

Black spot on pictures - cleaned lenses and inside

The spots can be in the inside of the lens settings to the CCD/imager.
If the cleaning of the lens is done well it can be a speck of dust logged in to the screen and having it on the image.
A careful cleaning in a dust proof set up is required.

White spots on images

Does the camer have a removable lens. Is it an SLR camera. If so, there probably is microscopic dust on your sensor, or you have some dead pixels on your sensor. If you can get to the sensor, you can easily clean it with a cleaning kit. The most effective way of cleaning is to blow it off with clean air. Be gentle. On an SLR it is necessary to lock the mirror up. Your instruction book will explain how to do that. For more suggestions, Google cleaning my camera sensor and you will get a lot of suggestions. :-)

Do not touch the mirror! Do a google search for digital camera sensor cleaning and you will find products and complete instructions for this delicate but relatively easy procedure.

It might be caused by some dirt on your lens (either front or rear element) but is more likely to be dust on the cameras sensor.

There are a couple of sample images of what this looks like here and here.

Dust spots typically have a softish edge to them and affect more than 1 pixel. (if it is just the 1 pixel affected, which a very sharp edge, this could be a defective sensor).

Following the instructions in the manual for cleaning the sensor. Avoid touching the sensor (unless it is with a specialist sensor cleaning brush) and avoid cans of compressed air; use a hand-blower brush instead.
