spots on picture

richgreenwood — Fri, 15 Sep 2017 02:05:40 GMT

Hey guys, please look at this image, and blow it up. There are spots in the background that I can't get rid of. It must be in the lens as I have cleaned the lens front and back, and the filers. Any idea how to fix this?

maybe a dirty sensor?

I am using a Canon T6. I have a second one so I am going to switch lenses and reshoot today to see if the marks are still there, then I will know if it is a lens problem or camera.

Usually dust inside of or even on the outside of a lens won't show up. They (dust particles) are OOF (out-of-focus).

You can clean a sensor but I would not suggest it to someone with limited knowledge. This is a good rule to follow, don't put anything smaller than a football inside your ear or camera. If you suspect a dirty or contaminated sensor find a shop or send it to Canon for a C&C. At the very least find some one that has done it successfully before first.

99.9% likely it is sensor dust.

As ebiggs1 said, have a qualified individual clean it. Its easy for someone who jknows how.

To really complicate this, I went back and took some shots. With every lens I can see the spots, so I have eliminated the lens as the problem. It is funny that when I went back, I can see the spots through the viewfinder also. Possible the mirror and the sensor have been contaminated. Obviously this is a serious problem that I need to resolve, so I think I will look for a qualified shop to clean it.

Probably not the same spots. Looks like sensor and viewing screen have been contaminated.

You are right. I cleaned the screen above the mirror and spots are all gone in the viewfinder, so it appears dust is the problem. I don't want to mess with the sensor, so I am calling local photo shops to see who can clean the sensor..

I was just wondering how dust got in there as I rarely change lenses, and I am looking back to when I got this camera and it appears it was there all along. My second T6 does not have this problem.

A very few we bodies wind up wind up with some lubricant splatter.

That sounds very possible as I wouldn't expect dust on the surface above the mirror. I have made an appointment with my local camera shop, and he says he is very familiar with cleaning these surfaces. Thanks for all the help!!

I've had my sensor cleaned by canon before. Obviously, they do a fantastic job! Mine was dirty from a shoot I did In Brazil a few years back where i had to change the lens a few times at the beach. Not my most brilliant idea. Contact CPS (Canon Professional Services). They are really top notch!

" Possible the mirror and the sensor have been contaminated."

Spots or dust on the mirror will not show up in your photos either.

Changing your lens outdoors is a good way to introduce dust into a camera body. I have caused my image sensor to get dirty and dusty by sitting in a car on a hot day, with the air conditioning on high. Wind and breezes are your enemy. Pollen is your enemy. Static electricity is your enemy. Humidity and wide temperature swings There are a ton of ways to get your sensor dirty.

I do not know how you cleaned it, but I hope that you did not touch. Or even worse, get it wet with a cleaning agent or solvent.
