Recently i have found a spot in a very very limited number of my pictures... i did some testing and i have narrowed it down to dust on the CCD

here is a 100% crop of the dust mark (you need good eyes! its a circular discolouration



what must i do to remove it or should i just live with it as it only shows up in 1% or less of my pictures... it is easy enough to edit out and it rarely shows up. i have gone to many of my pictures done some crazy editing to make the dust mark show up and it is impossible to find in 99% or mor of my pictures (i have not tested all but i have seen all the pictures i have taken).

what to do?

wow that's pretty intensed. i'm no expert so what type of testings did u carry out? How did u arrive to the conclusion that it's dust particles? Anyway, get it serviced? since still under guarantee? or u might be able to get a replacement?

But if u can't find dust particle in 99% of pictures, perhaps it's not dust? I suppose someone can come up with a theory n reason? Good luck tho

How the heck did the dust get there? I can see what you are talking about, which is a miracle because I usually can't. I'm looking forward to seeing the replies on this one

the M603, 602 and 7000 can suffer terrible from it, in fact J-Kirk has a stripdown for the 602 on his website, it's down to poor sealing of the camera body (Fujis are VERY poorly built even if they DO take good photos), I had an M603 here which looked worse than my 1DS does for it! - never heard of it with a Pan before .

Mike,

I had the same problem on my first digicam (Pentax Optio 330). In that case it was actually dust between lens elements. Pentax replaced the lens under warrantee and all was well.

I can see how dust can make its way onto the sensor. I've always kept a Pemaraal adapter and UV filter attached to the camera because I'm a little paranoid that dust can work it's way in through the gaps between the lens and the camera body.

Some say the fact that the sensor on a dSLR is exposed during a lens swap is a bad thing. I've always thought the opposite because at least you can clean it without dismantling the whole camera.

I'd first take it back to place of purchase and ask for replacement. If that doesn't work, I'm sure you can send it in for service.

Good luck.

Mike

P.S. I suspect the spot is on all images, you just can't always see it. On my old cameras, it was most obvious in clear blue sky shots just like your example.

This is not dust on the CCD, this is dust on the lens.

I have takn pictures at multiple zooms, multiple apetures, multiple ISOs and whent he spot appears its allways in the same location... lower right corner...

if it were smething on the lens the location would change

then i ask... in pictures across several weeks, why would it appear on random pictures in the same location each time... perhaps you are talking about it not being on the front lens but on an internal lens

I agree with Rob. Dust on the CCD would be a sharp silhouette of the dust particle or a black speck since dust tends to be tiny. Dust on the front element will spread it effect more or less evenly over the whole image thus images are only really effected by fairly dirty lens unless in a lens flair situation. My guess is its dust on last element before the CCD. Close enough that its effect is only spread over a small area.

I agree. This is exactly how my old camera's pictures looked and the dust was on an element close to the sensor.

With it only appearing on 1% or less of my photos should i even bother to have it cleaned?

Is it only showing up in contrastless (is that a word?) photos? I'm thinking it is always there, but it is only visible when that part of the frame is fairly light in color and has no contrast.

When I had the issue it was center frame L to R and about 1/3 from the top of the frame. It showed up in a lot of outdoor clear sky pics because the sky was usually in that area.

I guess it's up to you, but I'm pretty anal about that kind of stuff and would probably send it in. But that's just me.

I should think that a piece of dust that large on a lens element could be easily seen with the aid of a lighted magnifier. Small specks simply drop out of focus.
 
i keep my main (front) lense clean... and i don't consider this a big spot when compared with the rest of the picture... it only appears in low contrast BUT it doesn't always appear in low contrast... if all i can expect is to see it in low contrast then it is edit outable so for now i think i will sit on it... that is untill it gets worse

then my opinion is that you aren't seeing it... its not 1 pixel... its a darker circular patche in the center of the example crop... I really don't want it mapped out cause that would really ruin my pictures

Mike,

You're going to just have to force yourself to do something creative with your free time.
Free time is precious.

I guess I've never thought of taking a pic of a solid color and looking that closely to see what I can find.

And I can guarantee you that even if I ever had my pics published or even on display in an art gallery blown up is anybody ever going to look that close.

But every 100th picture you post I'm gonna have to say nice job Mike but when are you going to do something about that dust?

origionally that was part of a set of pictures of sky... testing noise levels at different ISOs... i didn't look hard... i did a manipulation that expands all details (subtle details become strong and strong details become over bearing) this is how i noticed it... not deliberately but by accident
