Help Please

[Dr Hal]

I have checked my sensor and checked my lens and I just do not know what is causing the spots in the sky. I am sure that on this forum someone will know. What can I do about this?? I am going on a trip to Iceland with my granddaughter in two weeks and I do not want to have my pictures ruined.

no dust at all on sensor ?
Might be a stray hair in the body settling on the sensor at random ?

Does the spot reappeared on same location every shot?

Back to the old days I had a fixed lens bridge camera which had also developed similar spot on photos. It was fungi and because it was out of warranty, cleansing is not economically advisable so I was forced to upgrade.

Hard you lifted up the mirror and examine the sensor surface by a powerful torch? Or had you wide open your lens and inspect the interior glass elements toward a light source? If it is on the sensor you might try to wet clean it. If inside the lens, I suppose it must be service time.

It might be a fragment of hair or some such. That can show up at small apertures like the f/18 you used for that shot.

You say you have checked the lens and the sensor. Did you use a loupe to check the sensor? I find that sometimes I can't see things on the sensor even if I do use a loupe, let alone with naked eye (with spectacles in my case). That is normally for dust spots though, which are smaller, but even so there may be something there you can't see.

Have you tried cleaning the sensor?

G9. No mirror.

Preferably using a blower first, in case that is sufficient? That is what I do.

It looks like ET activity up in the skies...just kidding!

I would use a blower first and see if its a loose dust particle. Of course try to point the camera down while doing it and whatever you do don't use air compress cans. If that doesn't work I would use the wet method of cleaning kit. I have one called dust aid. There are youtube videos that show you this. I also have a static brush to pick up these particles but at a much lesser. success.

It it is dust on the sensor, there are two courses of action:

1. Either clean the sensor yourself, or get someone else to do it for you.

2. Decide not to worry about it, and just clone/blur it out in PP.

Personally, I'd go for option 2.

I have a couple spots like those on my sensor just not a long squiggle. They only show up at higher apertures in blank areas of the image. On the rare occasions that they're visible, I clone them out like this...



Took 30 seconds in PS Elements. If you don't want to do this, you'll have to clean the sensor.

It's an out of focus dust hair sitting on the AA filter, there's also an oil based circular mark to its right. Don't be suprised if you can't easily see them with even with a loupe as they will be a lot smaller than you might expect - also they are on the opposite lower side of the sensor.

A wet clean with Eclipse will rid you of both. Eventually these things will reappear. I wet clean on average two times a year.

One effect of shooting at f/18 on M4/3 is that any dust on the sensor becomes very visible.

However, the most important effect of shooting at f/18 is that you are going to get quite severe diffraction effects because of the tiny aperture diameter. This will significantly reduce the sharpness of your image.

On M4/3 diffraction effects start to become visible at apertures smaller than f/8, so avoid using then unless you really have to for depth of field reasons.
