I am getting this black spot at the same place every time I am taking a photo.
I am looking for an explanation of the issue and a solution to remove the patch. I am a beginner and if needed I can provide more photos of same issue.

To investigate sensor dust, perform the following test:
- Close your aperture as much as possible (high F-number). This makes the sensor dust more visible.
- Increase the focal length as much as possible (zoom in).
- Focus on infinity (not sure if the focus part is actually necessary) on a bright, uniform background. I've found that the blue sky works well for this purpose.
When I had horrible sensor dust, my test photo looked like this (images darkened to enhance visibility of sensor dust):
After professional sensor cleaning through a photography shop in my area, it was almost completely gone:
In the former case, there was dust visible on most of my photos, in particular in the sky. In the latter case, I have not noticed any dust.
Both photos taken at F/40 with 200 mm focal length (Sony α6000).

Do you happen to have such photos of the sky for horrible sensor dust (already shown), clearly seen sensor dust (sompething like OPs issue), "I think there's something wrong with the camera" dust, "invisible" dust and "After the professional cleaning" dust?

You can also take this picture in front of a white wall. You can then use the picture as a mask in order to remove the dust in post-processing. You should also clean the sensor but you might be able to save already taken pictures this way.

@EricDuminil I did try the mask automated post-processing, but I've found that any automated processing for my many hundreds of vacation photos was producing undesirable results, probably because in-camera processing and/or image stabilisation was causing the dust in the final photo to vary by some pixels. See this question.

@Crowley I've added the "after cleaning" photo. I have since learned to prevent sensor dust from becoming too bad (always point the camera downward when changing lenses), so I (fortunately!) don't have intermediate examples (yet).

There's probably something on the sensor - maybe a dust particle.
You can check if the Canon camera has a sensor cleaning option and use it or take the camera to a local repair shop and have the sensor cleaned there.
Or you can clean the sensor yourself, but I wouldn't recommend it, as you are a beginner.

Dust on the sensor, as other answers have suggested, is a strong possibility. Another possibility is dust on the rear element of the lens. If you change to a different lens and the spots go away, that's the culprit. If they're still there, it's the sensor. If it's the lens, a cleaning cloth and a gentle touch will fix it.

Could be dust on the front of the lens, too! That's the easiest cleaning.

@WBT, dust on the front of the lens is usually so horribly out-of-focus that it shows up as a loss of contrast rather than as a distinct object.

Also, try to avoid using very small apertures (f/11 or f/16 or even higher) until you have an opportunity to clean the sensor or get it cleaned - small apertures make dust particles on the sensor far more pronounced.

If you see the same spots on all photo this is definitely dust spot on sensor. To be precise this dust do not touch sensor itself but the filters in front of the sensor.
To clean this you can try few ways.
- Use the "Clean sensor" function if your camera as this function. This will vibrate the sensor and try to get rid of dust
- Use blower to try to remove the dust. This should be done on
switched on camera and directed down the lens mount (to be sure
dust will go outside the body). Also you can activate mirror lockup
to have better access to the sensor. And also its good camera to be in liveview mode. - Send your camera to repair shop for cleaning.
- And last, try to clean the sensor by yourself.

Using a blower without the mirror locked up will do next to nothing. In fact, it's worse, as it risks blowing dirt into the viewfinder where it's very difficult to get out. Also, you want to blow up into the sensor, so you don't have more dust raining down into the camera while you're trying to clean it.

@DavidRicherby, did you read my answer? Did you saw I mention the camera position? Did you read I mention liveview (which involve mirror lockup)?
– Romeo Ninov

Yes, I read your answer. You say "blow down the lens mount", which suggests that the sensor is facing upwards; it should face down, as I said. You say "also you can activate mirror lock up", which suggests that locking up the mirror (by whatever method) is purely optional. It's not optional at all: it's a 100% necessary part of cleaning. Further, my understanding is that you don't want the sensor to be active while you're cleaning it, so live view is a bad idea. (I may be wrong on that; something about static charges on the working sensor attracting dust.)
– David Richerby
2 days ago
@DavidRicherby, sorry for not be native speaker, And think a bit about the sensor. Even if you have mirror lockup this do not mean shutter will be open. And you will blow the shutter, not the sensor. Right, there will be static charge. But otherwise you will have no access to the sensor at all.

@RomeoNinov There is only one correct way to manually clean a DSLR sensor, and that is to activate the manual sensor cleaning option, hold the body facing downwards, and use a blower to gently blow upwards into the camera. Mirror lockup will not open the shutter. Liveview may have unforseen consequences. Never use any other method than the official one for your camera. If the camera does not have a manual sensor cleaning option, take the camera to a technician. Cleaning the sensor by some other method will void the warranty if the camera is damaged in the process.

It's more than likely a pics of dirt or dust on your sensor. You can get special cleaning tools on eBay that doesn't cost that much. And there's plenty of videos showing you how to clean it be very careful though!

Could be dust on the front of the lens, too! That's the easiest cleaning.

@WBT, dust on the front of the lens is usually so horribly out-of-focus that it shows up as a loss of contrast rather than as a distinct object.

OP's looks pretty out of focus compared to yours.

Also, try to avoid using very small apertures (f/11 or f/16 or even higher) until you have an opportunity to clean the sensor or get it cleaned - small apertures make dust particles on the sensor far more pronounced.

If you see the same spots on all photo this is definitely dust spot on sensor. To be precise this dust do not touch sensor itself but the filters in front of the sensor.
To clean this you can try few ways.
- Use the "Clean sensor" function if your camera as this function. This will vibrate the sensor and try to get rid of dust
- Use blower to try to remove the dust. This should be done on
switched on camera and directed down the lens mount (to be sure
dust will go outside the body). Also you can activate mirror lockup
to have better access to the sensor. And also its good camera to be in liveview mode. - Send your camera to repair shop for cleaning.
- And last, try to clean the sensor by yourself.

Using a blower without the mirror locked up will do next to nothing. In fact, it's worse, as it risks blowing dirt into the viewfinder where it's very difficult to get out. Also, you want to blow up into the sensor, so you don't have more dust raining down into the camera while you're trying to clean it.

Yes, I read your answer. You say "blow down the lens mount", which suggests that the sensor is facing upwards; it should face down, as I said. You say "also you can activate mirror lock up", which suggests that locking up the mirror (by whatever method) is purely optional. It's not optional at all: it's a 100% necessary part of cleaning. Further, my understanding is that you don't want the sensor to be active while you're cleaning it, so live view is a bad idea. (I may be wrong on that; something about static charges on the working sensor attracting dust.)

@DavidRicherby, sorry for not be native speaker, And think a bit about the sensor. Even if you have mirror lockup this do not mean shutter will be open. And you will blow the shutter, not the sensor. Right, there will be static charge. But otherwise you will have no access to the sensor at all.

@RomeoNinov There is only one correct way to manually clean a DSLR sensor, and that is to activate the manual sensor cleaning option, hold the body facing downwards, and use a blower to gently blow upwards into the camera. Mirror lockup will not open the shutter. Liveview may have unforseen consequences. Never use any other method than the official one for your camera. If the camera does not have a manual sensor cleaning option, take the camera to a technician. Cleaning the sensor by some other method will void the warranty if the camera is damaged in the process.

It's more than likely a pics of dirt or dust on your sensor. You can get special cleaning tools on eBay that doesn't cost that much. And there's plenty of videos showing you how to clean it be very careful though!
