Creative procrastination is wonderful. Being of the indolent persuasion, I can spend hours figuring out how to avoid 10 minutes of actual work. And frankly, such an exercise can lead to a whole host of creative ideas, most having nothing at all to do with the original problem. But I digress.
I've had my DSLR for a few years, and never felt strongly inclined to actually clean the CCD. The notion that I might screw up the CCD and have to spend major bucks getting it replaced held absolutely no appeal.
But over the past year, it became apparent that something was going to have to be done. I had used a rubber bulb syringe to blow dust off the CCD a number of times, but images continued to show a small spot of discoloration that looked like a dust spot. It persisted even after repeated "blows." It wasn't a major deal, but having to retouch it out of every image was getting old.
So I bought the kit. Three "clean room" swabs and an ounce of some magic liquid. $29.95 plus 6% tax. Used car salemen should take lessons from those guys...
So anyway, I did the setup on the camera, removed the lens, and fired the shutter to move the mirror out of the way. I then placed exactly two drops of the fluid (alright, it was actually three...) on a swab carefully removed from its sealed envelope by the very tip of the handle end.
Then I gently swiped it across the CCD first in one direction and then back using the other side of the swab. Allowing a few seconds for the magic liquid to evaporate, I put the lens back on, and turned the camera off to reset it.
A quick test shot of a white card showed the dust spot gone, but there was a rather omnous dark line running across one corner of the image. Damn! That third drop must have seeped into the CCD and I'm screwed.
Fortunately, it was only a tiny hair, and a blast from the rubber bulb syringe sent it to unknown parts (probably lurking inside the camera ready to jump on the CCD when I'm creating my once-in-a-lifetime masterpiece image.).
So it wasn't as traumatic as I expected. Am I ready to do it again? Well, let's put it this way; if it ain't broke...
I use a 24-200 mm lens almost all of the time; I don't really have much reason to change lenses often, so maybe my cleaning job will last another four or five years.
$29.95 for three little plastic swabs and an ounce of something! And they say medical costs are out of control...
