Gang, I've had my beloved D70 for almost 2 years now and somewhere along the line I've ended up with a very troublesome "spot" that appears in light backgrounds (e.g. sky in background) marring what would otherwise be lovely images. The "spot" (it appears as a small circle, perhaps a drop of water) is in the top center of the framed image and I've been able to crop it out. If the background image is dark, the "spot" isn't visible. I understand that there's a way to "clean" the D70 along with enough warnings and cautions to scare the daylights out of me. Has any other D70 owner undergone this process? I do have a service contract that I can resort to if need be but I'm not keen on being without my camera for an extended period of time. I'll be glad to post an image to illustrate if that will help. Thanks in advance.
