Camera problem

[GfK]

On a lot of photos I've taken - particularly the ones with vivid blues, I'm noticing a 'shadow' in one corner of the picture.

Its evident in the top-left corner of the pictures I posted in these two threads:

Both shots were taken in portrait, but in standard landscape orientation, that dark splodge would actually be at the bottom-left corner.

It may be that a bit of cleaning is required, or could it be a sensor fault or something?

Any ideas on where I start looking for how to correct this?

Camera is a Fuji S5100 and its less than a year old (I think).

are you using a tube to attach a polariser filter or something? If you are using a tube, have you put the camera on the setting for using a tube? Also, you might need to zoom in a bit to get rid of the vignetting if you are using a tube.

hmm,

first of all, do you have anything screwed to the front of the lens, say a filter or even a lens hood for flare ?
if so , it could be Vignetting ( spelling ) at one end of the zoom ??

does it happen on every pic....if not i doubt its the sensor

does it only happen if its sunny ...it might be flare from light bouncing around inside the lens, and you need a lens hood,

if these ont answer the question , it might be the camera has to go back to Fuji for a service/repair, but that will cost money to find out , possible

bum....beat me to it , lol,
like marianne i had a fuji s7000, i had the tubes for the filters etc, it did give me a similar result on some pics

[GfK]

Yep, tube + UV filter on both shots, however, that was the first solution I thought of and I get the same results when these are removed.

The lighthouse shot used zoom, the other didn't.

It doesn't do it on every shot. The only comparable shots (I know they suck, so don't tell me!) I could find are these - the first taken 24 hours before the lighthouse one, the other taken 1 hour after the lighthouse. No shadowing evident in either:

did you zoom in a bit or use the widest angle?

[GfK]

Always zoom in a tiny bit to avoid 'warping' at the edges of the pic.

just looked up the problem on google and it would seem that vignetting is a problem with the 5100

You got a link to that? I never found anything conclusive.

[Marianne]

type ' Fuji S5100 vignetting ' in google

[GfK]

That might explain why I couldn't find anything before - didn't quite know what name to give it.

This is quite disappointing. I mean its hardly the end of the world, just one of those things that annoys you quite a bit.

Think I need to start saving for my Eos1D.

*rummages through pockets* :( :(

[Marianne]

aww...don't be sad...its a fab camera and takes stunning macro shots! stick it on a tripod and take some now! I wouldn't have noticed the vignetting if you hadn't said anyway lol

[CT]

Blimey, is that it? I've seen far worse vignetting than that, it's hardly noticeable and someone with your cloning skills wouldn't have any problem sorting it with a couple of clicks. ;)

Think I need to start saving up to buy Arkady's D1x

It's waiting here for you mate...:D

this might be a silly question but how do you say vingetting? :)

[chuckles]

vin-iet-ing ;) LoL (At the same time sounding like Charles Aznavour)

[Marianne]

vinn yetting

[chuckles]

Oh dear!

[Marianne]

:banana: lady in red......nah sounds nuffin like it but talk to me in that french accent ...mmmmmmmm......:doh:

[CT]

Vin yetting it is - derived from a way of presenting pics fading or darkening towards the edges which was very popular in Victorian times. This pic would be described as a vignette...
