Sorry, can't think of a technical term for this. I use a Fuji XT3 and on several occasions I have noticed what can only be described as a vague, worm like shape appear in my photographs. Not all of them it has to be said, and mainly if there is sky present. I would possibly have attributed this to some effect of the light, or the effect of a zoom, but it has happened on another, fixed lens in much more subdued conditions. I can't see any obvious trace of dirt on the lens, or the sensor, so I'm hoping that you guru's might have some suggestions.
 
Could it be sensor contamination only showing up at smaller apertures with a plain background? If so it could be a small fibre on the sensor rather than a speck of something which would produce more of a spot. If it is a fibre a blast with a rocket blower might shift it.
 
This will be an interesting thread.

How are you viewing them, and what software are you using?
 
There was a thing a while back when using certain photo editors with Fuji files that caused exactly that.
Can’t remember which editor it was mind.

I did initially think this could be the dreaded Fuji worm thing but as the OP said "a vague, worm like shape" as in a singular worm I thought it might not be that and might be a fibre on the sensor rather than the multiple worms like effect possibly caused by processing.

Ah, I know where you're going with this. :D I use Capture 1 Express at the moment.

I agree, that was among my first thoughts. But I've studied the sensor under good light with a magnifying glass and can't see any evidence of debris on it at all.
 
Sounds to me like a small hair on the sensor, you're noticing it more in strong highlight areas because you're stopped down more maybe?

Aye, god forbid anyone raise that ole Fuji worm issue :ROFLMAO:

A non existent issue for me during my years using Fuji btw


Too late, can of worms open :facepalm:
 
The worm is likely from outer space, and could be in your camera &/or computer, and the only answer is to destroy them both by incineration at extremely high temperature as soon as possible. Are you insured?
 
You might be able to detect the venomous little beastie here. I've checked another photo and it would appear to be in the same position. So maybe there is some detritus I can't detect.

It had crossed my mind. :D
 
That's a smudge, you just need to clean the sensor

I think you are right. Having looked again, and under a certain light, there was a teensy mark that I hadn't detected. A good puff seems to have shifted it, so hopefully that might be the end of it. Thank you for all your help gentlemen.

I would do a wet clean also, you can get kits for less than £20, and you get a bunch of cleans from it.
 
I'm pretty sure that was a fibre.
