Does My Sensor Need Cleaning?
Apr 6, 2016 11:28:54 #
I have my Canon T3i several years now and have not cleaned the sensor.
So based on the advice I get from my UHH search, I took a picture of today's clear South Carolina blue sky using my EF 24-105 L lens. I zoomed in on it on my laptop, and cannot see any spots or specs.
I don't want to clean the sensor, if it doesn't need it. Would a pro mind taking a look at the photo and tell me if these 69 year old eyes and my laptop are telling me the truth, or are there defects that I don't see?
By the way, I had to focus on a distant tree in order to get the camera shutter to release on the sky.

It looks pretty clean to me but to be completely honest, I am looking at this picture on a phone with a shattered screen so I may not be the best source for a comment. :)

It looks like you shot this at F5 according to the EXIF data. Go out and shoot again around F16 or higher. Dust becomes more readily apparent when you close down the aperture. Blue skies works great.

Agree, shoot at the smallest your lens allows, usually f22. Then you will see any dust spots and you won't need any help in spotting them.

From what you posted here, absolutely not. But, see above.

Shoot it at f22 and look at it then. I shot a lot of spots with my old D600. But that's another story.

I've never cleaned the sensor on my Nikon D80 and it doesn't need it, so it's not uncommon. But my D800e sensor needs regular cleaning!

Thanks to Haydon and All Who Suggested that I shoot at F16 or higher.
This one was shot at f/22. I don't see any spots. What do you think?

For the most part, Lookin' Good! No spots. But there appears to be a small smudge or something about an inch down from the top, just left of center. Maybe it is my monitor(or my glasses, LOL!).

Nikon_DOn: No, ain't your glasses, there's something there.
A Pro once told me to take a shot at a white background or the sky. Convert to negative image and the spots become very visible

Looking like a smudge top left center and possibly a spot top right almost half way down....
Actually looking again at the download, appears there are 7 very minor spots barely showing up....A rocket blower might be all you need to clear them off. Also easy corrected in Post processing.

OK,
I see the left center smudge, the center right spot, and another spot at top left.
I'll try a blower first and retake the picture.
Thanks again to you and all for your expert advice.

Actually, reminds me to get my blower out and blow out my D7100 after a weekend's shoot ;)
