Anyone identify the problem

[Moby]

Hi Guys,

I've had a mark come up at the top left of a lot of my images when there's a steady coloured background. It's like a dark patch. It's not the lens as it doesn't seem to matter which one I'm using.

See attached examples.

Can anyone help?

It's a D40x BTW.

Cheers

Dust on your sensor, basically.

Yup. Dirty sensor. Pretty much unavoidable tbh.

Having looked again I think it might be a bird actually. The f*****s following you around! lol

lol - next question ...

how do I sort it? Air duster can?

 

[Lagerlout]

There are cleaning kits available for you to DIY..... or you can take it/send it to somewhere to do it for you.

I'm still PP'ing the dirt out of my pictures so haven't got round to getting it done. Others on here who've done it will no doubt advise.

Show's you the methods... not for the faint hearted I might add!!

All I've ever attempted is blowing it with a bulb blower. Which did work to be fair.

Actually came free with a magazine subscription that cost less than the price of the brush! Great piece of kit, it won't get rid of stubborn stuff but if you use it as soon as you notice something it does get rid of it. I've been using mine on my current camera since March and it's still dust free.

That's a homing cloud.

Got the same on my D40.. Sucks because I've never taken the lens off since first got it. >.<
