    I took about 1.2GB worth of pictures while I was in Europe. And I notice that a lot of the pictures with sky in them reveal that top 2 corners are darker (and probably the bottom 2 corners as well, it's just not as noticable).

    What causes this? I'm using digital btw.

    Thanks in advance.

    it's called vignetting, cause by a lens hood or filter or something on you lense that's in the field of view of the lense.

    or a poor quality lens at its widest aperature. usualy its on wide angle lenses, wide open and with filters.

    if they were RAW files, Adobe RAW in CS has a conversion to add/subtract it

    it "can" happen on any lens. were you using any adaptors or filters or sunshades? were you using the widest aperature?

    well there ya go, try stopping it down. Usually the sharpest f-stop is 2 stops from it's widest spot. you won't get any vigneting at the spot unless you are possibly using filters or lens adaptors
