That's not always as easy as it sounds... DSLRs are easily prone to getting specks of dust on the CCD, and this is not always an easy thing to remedy. I have a couple spots on my D100 that I've been dealing with for a few months, and it appears that the only solution is a fairly costly cleaning... |
I was thinking of dust on the surfaces being photographed, not specs on lenses, as per the cat before/after photo. Specs on lenses, yes, I agree, can be a pain the the butt to clean, though in theory ought to produce only tiny imperfections in the photo, so I'd lump them in the category with 'hot pixels'. Just out of curiousity, I went and took a look at your last few challenge photos -- does the dust account for the small darkened spot above "Earth am" on your Postcard entry and the small darkened dot in the clouds in the Weather one? If so I think we're talking about the same sort of couple-pixel problem and I'd be happy to allow it to be cleaned up; I had to search to see either of those and I didn't spot it on the intervening photos.
So, "hot pixels or small specs of lens dust not resulting in an imperfection larger than a few pixels square" too specific? :) |
