I'm lousy as far as clone stamping skills are concerned, so that presents a problem. It seems like every time I switch lenses, the sensor gets sullied with a varied, sundry assortment of undesirables. Many of my photos have been practically ruined. The lady in the camera shop I visit said in no uncertain terms that I am NEVER to EVER touch the camera's sensor, no matter what kind of genteel material I employ. So, they sold me one of those squeezable air pump doohickies - one larger than the one I already had. Last Thursday I sat on my couch and squeezed and pumped until my hand was sore ( ), and then continually went outside to snap a picture of the sky for test purposes. Resultantly, I had to take a lens cloth and apply it to my sensor to get some lint off the thing. That air pump just wasn't going to do it. Now, for just a standard photo, the crap is barely noticeable. But when I try and do an HDR, the sensor dust hideosity comes to full bear, and I'm yet again confronted with the yearning to take a cloth to my sensor again. Please inform.
