Friends, This beautiful morning on the way to the Wolf Center in Ely Minnesota, the temps were around zero F, so frost was very heavy near Lake Superior.  The bottom image is of the same region.  I have globs of something on my sensor that will not clean off with the sensor cleaning kit, also the dust delete software solution by Canon has limited range of removal capabilities.  Found a Photoshop solution that seems to work with these images, make a duplicate layer of the background, run the filter/noise/dust , set the level to 30-60, this will blur the image significantly but will also get rid of globies, now put a mask on this layer and paint with brush to get back the detailed areas, cool , it works, til Tomorrow MJ
