Spots on pictures after downloading

Most of the time you see "spots" on your pictures, they are induced by dust on the sensor. Nothing to panic about, it happens in all camera's where you can switch lenses, like in your 60D.
To make sure what I tell, you can make a dust retention picture.
Pot your camera in manual, or Aperture priority. Put the lens (any lens you own) to highest aperture number (22 or higher). Switch to manual focus and turn it to infinity. Then make a picture, from a with sheet of parer, with lots of light.
The picture that you made, can be viewed on your computer. To start zoom in, to the place you last saw "spots" I think you can see blurry spots around there.

To get these spots away, you could go to a service centre, but you also could try to remove them yourself. In your manual, you will find how you can put the mirror up and how to opener the camera shutter for cleaning. With a special brush and a bellow, toy can remove most of the dust on your sensor. Sometimes debris will not come lose when you try, then you could try a "wet" cleaning.

Don't use brushes you have at home. Use special tools made for camera's. That also goes for the wet cleaning. Everything in the camera is very delicate, so handle it with care.
If you don't trust yourself, goto a service centre. But be aware dirt on the sensor will happen more then once. If you are young, learn it yourself.

Do the spots only occur when taking flash pictures and do the spots look like "soap bubbles" and appear in different places in each picture? If so, these are dust particles reflecting the flash back into the lens. It's a problem with all point and shoot cameras because the flash is so close to the lens.

Do these spots look like soap bubbles and do they appear at different places on each picture? Also, do they only appear when you take flash pictures? If so, these are dust particles reflecting the light back into the lens because the flash is so close to the lens. We all have this problem.

If these spots look like bubbles appearing in different places on each picture and only in flash pictures, then what you are seeing are dust particles in the air reflecting the flash back to the lens. There's nothing you can do to prevent this.

If the spots appear in the same place in each picture, then you have dust on your sensor. Google the words "how to clean a DSLR sensor". You will find sites explaining the procedure with pictures and where you can get the supplies. You can do this yourself...it's easy.

If the spots appear on flash pics only and are in different places on each photo, then the spots are not on your lens. Those are dust particles reflecting the light from your flash. It's a common problem with point-and-shoot cameras.

If these are like "bubble" spots and they appear in different places on each photo, I'm guessing you're shooting flash pictures indoors. The spots are dust particles in the air reflecting the flash. This happens on small point-and -shoots because the flash is almost in the same plane as the lens.

I think your lens are dirty. Buy lens cleaner from your nearest electronic store. Or do what I do, breath a mist on the lens and rub with a clean cloth. It always does a trick. Don't use glass cleaners.

you should be able to clean the exterior of the lens with a clean microfiber cloth or lens cleaning papers (available at even wal-mart). If the spots are in the inside of the lens body, you have to send this in to be cleaned as the camera will have to be disassembled to do it right.

As is common in many compact digital cameras where the built-in flash is very close to the lens strange reflections can appear in images under certain conditions. Particulate matter in the air in front of the lens (between the camera and subject) such as water vapor (as in a cloudy day), smoke, dust or other items can reflect light directly into the lens causing neutral colored white/grey semi-transparent spots to appear in the image. In extreme examples there may be many of these spots in an image or there may be only one per image. Also, since these spots are completely random they will move or disappear from image to image. For example, if two images are shot consecutively with the same camera settings one image may have spots while the other is clean. To avoid these spots: When possible, avoid photographing in smoky, dust, or cloudy areas Do not use the camera's flash in locations such as above Use an external Speedlight flash if a flash is needed Review images on the camera and re-shoot if spots are visible Cleaning the lens will not have an effect on these spots, as the particles that cause this are not on the lens itself.
