I went out shooting today with the brand new Canon Digital Rebel XTi I got for Christmas. When I got home and uploaded the pictures on my computer I was disappointed to see that many of them were hazy with bizarre, colored streaks through the images. I have no idea why this is. I took outdoor pictures at the beach yesterday that came out fine. The only difference today is that I added a UV filter. I had the camera on "Auto" yet still many pictures were hazy, washed out, and lacking sharpness. Example 1 Example 2 But even more puzzling, without changing any settings, filters, or anything some of the photos came out fine: I'm really confused and I was wondering if anyone could provide some insight as to why this brand new camera is producing images like these. Thanks.
