dslr dust on sensor

[alacant]

Hi. I've a canon 700d, modified for red. There's a dust mark. Flat frames do a good job of (almost) eliminating it from final images but I'd like to have a go at removing it. I can't see anything by holding the shutter open on B and I've tried one of these but still it remains. Short of sending it to Juan @ cheapastro who modified it, I wonder if anyone has developed a safe method for removing such? TIA and clear skies.

Hi,

dont think you will remove as the dust will be between the sensor and the second filter that is left in the camera after the mod..

maybe return to where the mod was done

Don't be afraid.  There are quite a few videos on YouTube showing how to do it.

A good start is to lock up the mirror then take the lens off, and hold the camera upside down.  Then use a filtered  air blower (don't be tempted to blow in from your mouth) .

Then refit the lens and take a picture of something bright like a clear sky or a white sheet that fills the frame with the aperture set at f/16 higher.  Then take a look at the image.

If that doesn't work then move on to wet cleaning

I used a cleaner from www.visibledust.com, there are others out there, make sure you get one that is the correct size for your sensor.  It worked a treat after one wipe.

I removed a hair that has been bugging me with that exact method this morning.  I wouldn't normally worry,  but I captured a few sunsets that showed it early on.

Thanks everyone. I think I'm gonna be brave and have a go myself although those kits are expensive. I doubt that the dust is trapped as earlier flats are clean.

Would not worry about it, just clean the sensor once in a while. I use a CLS Clip filter and it never leaves the camera just for this reason, it acts as a nice seal against dust. A little dithering between frames is the very best way of taking care of dust.
