noticed a couple of marks on the wall that I cloned out in PS. IBad idea that! You risk the probable deposition of propellant on the sensor which will give you "dough-nut" rings - no matter how bad the dust problem you should never use any air duster directed straight at the sensor as you will then have to rub the sensor to get the marks off, risking even worse damage.
then looked at the next image and they were on that in the same relative
positions.
http://www.jcole.co.uk/uploads/DSC_0003.jpg is my own blank wall with the
same marks!
I have opened the shutter and gingerly air-dusted the sensor
to no avail. Am I looking at "dead pixels"?Almost certainly - take it to "Fixation" T> 0207 582 3294. They can plot the dead pixels within minutes and then there is a software programme which gets the camera to use adjacent pixels to clone the dead ones and hey presto!
