Or is it just dust on some part i just don't know how to get to? I doubt anyone can really answer that but maybe someone has some insight. Regardless of what you guys come up with, i'll just be bringing it in to a repair shop to have them deal with it rather than risking having my clumsy ass try to fix it and then make it worse. Went to San Francisco with my wife and our Canon Rebel XT. We got it because we wanted to start using an SLR and learning about how to use it. We're in the infancy stages of just figuring out how the thing works. I took these pictures while playing with settings and seeing what changing this did to that and so on. Ignore the composition, lighting, or how the pictures turned out. What i'm concerned about is the squiggle that's visible on the pictures. It usually shows up when the sky is involved but not when there is a more complex subject in the frame. You can see from the first two pictures that it seems to change in amount of focus. You can also see in the third picture its position when the camera was turned on its side to take a picture. Dust? Scratch? Which part of the camera do you think this could be on? 1. Its very faint here but you can see it in the sky. If you're having trouble check out the second picture for position then look at this one again. 2. This time its much sharper in focus. 3. Its off to the right this time.
