What is this artifact?

[randello88]

fuji x100f, in every picture. It is in rue middle of the picture and it is visible almost only when there is the blue sky behind it. Is it a big deal? What is it?

 

[Bobthearch]

You used a phone to shoot the rear camera screen to ask a question about an artifact in a photograph? Holy heck...

Is there some reason you can't just post the actual photo???

 

[AlbertTheLazy]

I'm not sure what you are seeing, however...

Does it show in your recorded images?

If so, why not post one of those, rather than what you did?

If not, what are you worried about?

It looks like a dust spot but you need t o post a full size version of the file from the camera if you want us to see the real problem.

It's almost certainly dust on the sensor filter. The best way to confirm it is to aim the camera into blue sky and ramp up f-number to at least f/16. If it's very visible and well defined in those conditions, it's dust. (You'll probably see more of the little buggers too.)

Yes, I’m in namibia, not at home

 

[randello88]

Isn’t it strange that it is exactly in the centre? Is it normal/common to have some dust that pops out against blue sky or is it a big problem? Since my camera is a fixed objective one, is this problem existent since i bought the camera? No possibility to check my older picture for many days to come. Thanks

 

[randello88]

It shows in my camera images and also putting the sd in another camera. I can’t make a better post since i am on holiday and I won’t be able to access my pc for days..sorry

No.

If your camera has dust on the sensor (most cameras do) it's going to be most visible when shooting against a solid color and a small aperture.

Since my camera is a fixed objective one, is this problem existent since i bought the camera?

How would anyone know that without seeing similar photos taken when you first bought the camera?

No possibility to check my older picture for many days to come. Thanks

So come back and ask then.

So after you get home, post a sample for us to see.

Whether it's dust, a defect, or your imagination, what could you do about it in Namibia anyway?

I was asking if it is possible that dust gets in a fixed objective camera. I am not an expert of cameras from a technical point of view.. anyway i had never noticed it with my two other cameras, have i just been lucky not getting dust on the sensor of those cameras?

If you have dust on the sensor, then the obvious answer is "yes."

 

[randello88]

1) if it is (probably of course, nothing 100% sure) normal i’d just ignore the thing for the rest of the holiday.

2) if it is not normal but easily fixable i could take the camera to one of the many photography shops in the city i currently stay

3) since i am very passionate with photography and my pictures are important to me, knowing if there is a problem or not in my pictures is a big deal for me

 

[randello88]

It doesn’t seem too obvious to me. Maybe the dust was there from the assembly at the factory. Thank you for the answer, anyway.

There's just no way anyone can know that from the phone snapshots you've posted.

You might be able to figure it out when you get home and inspect your earlier photos.

But regardless of how long the dust has been there or whether it's in the exact center, the solution is the same: Taking it to a shop for a sensor cleaning.

It's certainly nothing to worry about while mid-tour in Africa.

 

[randello88]

So do you think having dust on the sensor is a minor issue? You should just keep using the camera without worries, maybe revolving the problem in post-production? Ì know those are newbie questions, hope you can help.

Yes.

But it could be more-minor or less-minor depending on the severity of the spot, number of spots, location of the spots, and the conditions necessary for the spots to appear.

Practically every digital camera gets dust and needs to be cleaned occasionally.

Whether it's just a minor distraction that nobody else notices or major one that's frequently visible in your shots will vary depending on the size or quantity of dust spots and the nature of your images. As you've discovered it's easier to notice in blue sky because it shows "texture" that you know shouldn't be there. If it appears where there's usually textural detail, then it's likely to be completely unnoticeable. Also, as noted, shooting at higher f-numbers will make it more noticeable, so if your photography involves a lot of deep DOF imaging that requires very high f-numbers, you'll see it more often.

It could have gotten into the camera during manufacturing. It could have intruded later on. Most cameras (even fixed lens ones) aren't completely sealed from dust getting in. The fact that you're now in Namibia might be something to note. If it's been windy and dusty there, it could've just happened and you may want to be more careful about leaving the camera unprotected when not in use (if that's been the case). Hard to tell with any certainty what's the source of the dust, though.

Good to ear that.. anyway, the shape of the artifact is like four "8", aligned and touching each other, exactly in the middle of the picture. Aren't those features a bit strange for a dust spec? Anyway, i managed to transfer some sample pics to my Phone right now. Ì know they are a bit underexposed, don't worr y about it. F16, 1/500.

 

[Bobthearch]

Could still be dust, or moisture spots, or a microscopic bit of oil. Doesn't really matter, the fix is the same.

Shooting at a tiny aperture, like f/16, is a good way to highlight even the smallest bits of dust and grime. I'm guessing if you had taken those pictures at f/8 or f/7, those spots wouldn't show up at all.

Honest, I don't think it's bad enough to even bother with cleaning.
