Hi,

Does anyone know what may be causing this spider-web effect? Only it keeps showing up on the bottom of my images. I just cropped this to the bottom left of an image, hope you can see it:

Any idea's what is causing it?

Thanks.
 
Thanks a lot - was rather worried! Will this item do the same job?

What do I do? Just hold it a bit away from the sensor and keep squeezing it to 'blow' the dust away? Obviously put it in sensor clean mode first.

Also sorry yes - noticed the image was quite small, just wanted to crop it so you could see it more clearly but it just made it a lot smaller too for some reason :(.

Thanks!
 
I would have to agree - looks like a dirty sensor- and a Rocket Blower should help remove the dust- if its a more stuborn dirt then perhaps a sensor clean from a reputable company like jessops

avoid touching the sensor with your fingers at all costs :nono:

Im guessing it does the same job :thumbs: hold the camera so the dust will fall out when you blow the blower- if that makes sense?

Yep thanks - so basically just hold the camera with the sensor facing down and keep blowing?

Thanks.

Dust on the sensor will show up, but dust on a lens will never show up on an image. I am on my phone so can't post a link to an article to show this

i actually thought the same but i was at a racing track getting shots of some drifters and at the start of the day my shots were clear but at the end the later shots were ruined by dust on the lens so i blew the photos up on my computer and figured out where the dust was and i looked at my lens and i actually found the same bits of dust on my lens as on my photos, it wasn't dust as such more like fluff off a wooly jumper or something but it was very large pieces anyway.

yes, hold it upside down and you are sorted :thumbs:
 
Don't rocket blowers have a filter though to stop any particles passing through, where as the Halfords one probably doesn't ?

Lol posted at the same time :D

Yep thats about it- look on YouTube for some detailed video's

A rocket blower is the tool for the job and cheap enough too around £10 or less

you can get them in jessops and yes, they do have a filter so stuff can't get through
 
Thanks guys - will pop in to Jessops later today.

Just wondering, why is it that if it's dust it looks like a spider web? Surely dust would just look like simple dots? It takes up about 1/4 of the whole image (all bottom left of the pictures I take).

Thanks.
 
no, i had dust like that but yes it could be the above ^
 
Still no luck guys, went to Jessops bought that then used it on my sensor but I still have the same problem.

Here is a picture I took for you:

Sorry didn't have many things to take a photo of!

If you see on the bottom left corner of the image you can see spider-web like things. Most of it shows up on the bottom half of the picture.

What shall I do? :(

Thanks.
 
Yes used LensPen for that, lens is crystal clear although my main concern is I purchased it used and didn't have a back cap, so might check that bit although pretty sure it's not the lens but will try.

Thanks.
 
Nope just cleaned the lens (back and front) :( still the same problem :(.
 
Have you looked at the sensor?

If you haven't... look. Get a magnifying glass and look. Remember that top and bottom are reversed so if the strange mark is at the bottom of the image you need to look at the top of the sensor. If there is anything on the sensor such as fibres or a stain you should be able to see it with a magnifying glass although you may have to wiggle the camera about a bit under a light to see any stain that may be present. Even if you can't see anything a wet clean may be worthwhile before going any further.
 
Thanks,

Didn't know a sensor worked like this. I held it under a light and could see these marks on the top of the sensor. Not sure what they are or how they got there.

Do you think I could sort this out with the wet clean?

Thanks.
 
It's possible that it's an oily deposit or the residue from something that's got in and evaporated so, yes, I think a wet clean is worth doing.

You can buy special cleaning swabs but what I use is a Pec Pad wrapped around a slice cut from an old credit card. To this I add a drop of Eclipse fluid.

It sounds like you've never done this before? If not maybe the ready made cleaning swabs are the way to go. You should maybe set aside a few minutes and Google your way to a vid showing how to do it. You can then search Amazon or ebay or wherever you shop for sensor cleaning swabs.

Remember that you're not cleaning the sensor itself but a filter above it so if you use good sense you really stand little chance of damaging it. I've cleaned my sensors so many times I've lost count, and all without damage.

PS. Once you've cleaned it do a test shot to see if it's gone. Don't be too upset if you need to clean it more than once. A good test is to select the smallest aperture (largest f number) and shoot an out of focus shot of a white door with the white filling the frame. It doesn't matter if the shutter speed drops to a second or longer as the shot will be out of focus anyway. In fact it'll be better if the shutter speed is slow and you could even wave the camera about a bit so that no door detail such as scratches and marks are visible in the shot. Once you've taken the shot, view it and see if the marks are gone. Easy Peasy. :)

Thanks will perform one. Do you not think these look like permanent scratches? That is my main concern :(.

Thanks.
 
I really can't say for sure. I don't know how it could be scratched unless someone has been very silly. I think it looks like some sort of contamination rather than damage so for the cost of some swabs it's worth trying to clean it. IMVHO.

You could have it professionally cleaned. It'll cost more but to be honest if you're going to use this camera it'll need cleaning again at some point so maybe it is worth doing so you know how to do it next time.

PS. Make sure there's plenty of life in the battery before attempting a clean. You don't want the shutter to close while you have swabs in there.
