Since you are new to photography I would take this and your pictures showing the problem to your local camera store. They will fix it for you and be able to sell you something in case it happens again in the future.

There is something on the sensor if blowing doesn't work the sensor probably needs cleaning no big deal I clean my own go to Copper Hill Images website they sell all kinds of cleaning kits just follow the directions that come with the kit its really easy to do. CopperHillImages.com

You could give up the camera and use a canvas and brush!

If its dust on the sensor keep in mind that just like your eye, it would be reversed on the sensor ie if it's at the top of an image it's on the bottom of the sensor and vice verse

My 2 cents... since the blem is in the same spot on a Hor or Vert shot, take the lens off and blow air on the inside (back) of the lens just to mak sure there isn't anything there before messing with the sensor...I'm just saying...

Since the blob is so defined, it's on the sensor.

Love your location title, CamObs

All this blowing onto the sensor talk and no one has addressed the dangers of doing this. Mainly that you may well be blowing a load more junk into your camera and onto your sensor.

Furthermore, no one has told this beginner that they should make sure the camera is switched off when attempting any of this, otherwise the sensor remains charged and becomes one huge dust magnet.

One final point is that not all blowers are made equal. Some of those cheap ones may well have residual dust (sort of talcum powder) inside the rubber bulb used originally to keep the rubber from drying out. Using one of these El Cheapos will only result in filling your camera with fine powder.

Cleaning a sensor is not difficult but it is a little touchy and screwing it up is very expensive compared to having it cleaned at a proper sensor cleaning location such as a reputable camera shop where they know what they are doing. Another problem is that a person may use too much fluid when using the swab, and even though it evaporates, there is a chance of leaving somewhat of a residue when used in excess.

And lastly, no one has told this person to be sure to keep the camera upside down to avoid gravity and dust falling back onto the sensor. Most of us don't live in a clean room (if any of us) and I am sure most houses will be filled with tiny particles floating around during the procedure to do this cleaning.

I bet most have the camera on a table, either standing there or laying on it's back when doing the cleaning steps, which should not be done that way, if you wish to keep the least amount of dust from falling back into the camera. Just some things to think about when doing this sort of thing. How many thought of any of this, come on be truthful? And if you are saying "I did, I thought of it", then why did you not mention any of it in any of the previous posts, hmmmmm???

You just did. Thanks for providing this info. It is very important. The info you mentioned is in the link I provided earlier. (Glad you stopped short of using all caps)

I had the same problem (dust on edge of sensor) a couple weeks or so ago and posted a question on UHH. I was told to put my camera in the upper shelf of the dishwasher. LOL

After several attempts to blow it off with a rocket-type blower and wipe it off with a sensor swab, it finally came off. Not sure which one actually did the trick.

It is gook on the sensor. Take your camera to a professional camera store and ask to have it cleaned. I just had mine done for $40, and had my camera back in 2 days.
