<p>Thank you for your responses. I will check the manual on sensors and try these approaches. I will look into more sophisticated editing techniques too. </p>

<p>I have a Canon Rebel XS that I have used pretty extensively for a few years, and still consider myself a novice to DSLR technique. I have the basic lens, 18-55 mm, and a telephoto 55-250. The camera has automatic sensor cleaning at shutoff. In the past few months of use, I have noticed that when I shoot pictures of birds in the sky or an object that has the sky in background, I will get a gray to black ring or half-ring and some spots of same shade in the photos in the sky area, often surrounding the object to where I cannot crop it out, rendering the photo ruined. It occurs with both lenses. I have cleaned my lenses and the inner cam components as best I can access with no change. It happens with autofocus with or without the flash, as well as in manual and other modes, though it may vary in intensity trying other settings. I have googled extensively and have not found much about this issue. Is there anything I can try to resolve this, or has my camera reaching end of life? It is not noticeable in taking portraits, landscapes if I have more and darker subjects/objects, yet I often shoot birds, lighthouses, etc. I do not see an option to upload a sample photo from my PC? Thx </p><div></div>
