Dear List,



I have been using ImageJ for the past few month (not an expert!) to correct images not often processed with such program, i.e. images of painting surfaces captured in macro mode with a compact digital camera.



When I use the 'shading corrector' plugin it generates green pixels in areas presenting particularly bright particles on my corrected image. I don’t understand where this is coming from and how to avoid such artefacts.



Can anyone help?



I’m attaching 3 images (reduced in size): original image, blank-field image and corrected image.




Thanks in advance,



Charlotte
