Sensor dust. Easy to clean. Blowing on it won't work. Need to get it cleaned. But unfortunately Copper Hill is no longer in business.

Yes, the professional you gave to did a lousy job.

Here is the B&H's Sensor Cleaning Kit (external link)

It's really easy to do. No more than 2 minutes.

Why don't you use Lightroom 'spot removal' function - you will see all sensor spots far more clearly.
Click on circle icon with arrow and then on the bottom of the LR turn on the 'Visualize spots' and move the slider.
From the shape of spots you can also determin if this is dust or oil spots.

I got back my camera today after returning it on Saturday. This time it's clean. He apologized but man, how did you not notice those spots the first time? Grrrr. Of course I didn't have to pay a second time, and I wouldn't have anyway.

I guess next time I'll try doing it myself.

I didn't know about that feature and actually never noticed the "visualize spot" below my image. :oops: Thanks for that tip!

Well... seems like I'm gonna have to pay this guy a visit tomorrow morning and see what he has to say. :-|

Or just wet clean it yourself. . Takes about 60 seconds and there is no risk of damaging anything and really no way to do it wrong for anyone with half a brain.

"Your" and "you're" are different words with completely different meanings - please use the correct one.
"They're", "their", and "there" are different words with completely different meanings - please use the correct one.
"Fare" and "fair" are different words with completely different meanings - please use the correct one. The proper expression is "moot point", NOT "mute point".

Here's the thing, if you wait until the sensor is covered with spots, it could be quite time consuming to get every single one.

Plus if they have been there a while, it can take more pressure and/or solution to clean them. If I was the guy cleaning your sensor, I probably would have erred on the light side seeing as you only noticed the issue when it was horrible.

If you clean it yourself, you can give it a quick and light clean more often and you have less chance of getting something really stuck on there.

One of my other favourite tricks for finding spots is to up the Dehaze to 100. That really bumps the contrast up in a way that makes those spots really stand out.

The one slightly annoying thing is that you cannot save the spot healing to a preset in Lr. Sometimes for what I shoot it would be really good if there were a simple way to throw on all the healing, then just delete or edit the ones that interfere with image content. I shoot aviation subjects against the sky a lot, but it would also be great for a lot of BiF shooters too I would think.

You can at least copy and past the Spot brush, so that is an option to speed things up, but it can mean you might need to swap back and forth to the sample image quite a bit, if you need to apply other copies across images.

That's what i'm doing. I copy the Spot brush from one image to the next and delete spots on the content or add some that were not necessary in the previous image.
Only now, I use the "Visualize spot" feature (thanks!!) to visualize them more easily. Before that I was browsing through the sky when zoomed at 1:1 to make sure there were not more spots than on the image I copied the Spot brush from. It took an enormous amount of time. That "new" feature help me go through this much faster.

I didn't have spots before that trip. It came because of the sand and wind. I don't have much of that where I live.
Coming back, I gave it right away for cleaning.

What I don't understand is that the second time I went to get my camera back, I asked him he he had tested this time. "I don't need to. I've got the equipment to see how clean the sensor is." I guess he meant a magnifying glass. But there was a photo on the camera (white screen) so he actually tested it. Why say he didn't? And why didn't he see those spots on the sensor the first time if he had the equipment necessary to see every detail? Especially knowing that he actually saw them with his bare eyes when I brought it back the second time. :rolleyes:

For whatever reason, he thought that he could get away with doing a slapdash job ... that you were going to be easy to please. But he misread you badly. Now he's embarrassed and defensive and uncomfortable about being found out. He's trying to save face ... but even doing that rather badly (forgetting to delete his test image).

I take it from your user name that you are female (my apologies if I've got that wrong). I'm sorry to say that this might have something to do with it. Car mechanics in the UK, where I come from, are notorious for patronising female customers and for taking liberties with pricing and specification of work required. They have a built-in assumption that women cannot grasp technical matters and that they can take advantage of that. A male who actually knows nothing about how cars work will likely get more serious treatment. Your camera technician may have been an example of the same sort of thing. It means, if you are a woman, you have to be a little more vigilant, unfortunately.

No! No! No! No! No! No! No! No!

Alas, you are right. Our daughter has become expert in deflecting mansplaining done by idiots several long rungs below her on the technical and business totem pole.

Guys, remember this: There are many great, wonderful and sometimes perplexing differences between males and females but neither overall intelligence nor technical inclination or ability happen to be on the list. Our initial blind estimate of female ability and subsequent treatment of them is a key question on our own intelligence test.

I would also try turning Dehaze up to 100 as well as using the Visualise Spots tool. The Dehaze trick will often bring out spots that Visualise misses, especially when using the fit to screen zoom setting. That way you don't have to worry quite so much about missing a bit of the image as you scroll about. I do have a 5K display though, so for my camera full screen is 80% plus magnification, so fit to screen isn't too bad. A simple click at the right hand end of the slider will set the Dehaze value, and I just click in the value box, and type the value to reset to the original value. Most of my own presets that I use have a bit of Dehaze set in them.
