Discovered UFOs in my PhotosI was taking pictures of the sky as I always do especially this day, March 17th, since it was so clear and bright. The weather was perfect. I was enjoying the day, seated in the patio, working with my PC. Then I heard and saw a green helicopter flying low and I tried to photograph it, but couldn't because because I had to adjust the zoom and could nto be fast enough, so I kept taking photos of the sky, towards the mountains and freeway 118, farther away. Later upon examining all the photos in my PC, I saw the object that looks like a saucer, shiny surface and all. (This is a crop of the original, zoomed-in photo.) Later in the afternoon, I heard another chopper, went out, and there was the same green one. I tried again, but it was too low to focus and I had my camera in zoom to take photos of distant objects, so I could not catch it. Again, I continued to take pictures of the sky at random. I waved goodbye to the green chopper as it went behind the trees and out of sight.The photos in the afternoon pictures look like triangular objects, I am sure these cannot be birds at a distance; they would have to be gigantic to photograph this way.The "saucer" like object photo was taken in the morning. The afternoon photos show dark triangular objects. The photos were taken with a Canon Powershot G10 digital camera. (This camera has a maximum resolution of 14.7 mega-pixels.) Since that day I have taken more photos and some days I have caught cylindrical, triangular and cigar shaped object. For 2 years of doing this I did not discover any strange objects in my photos but they are becoming a weekly thing.
