I am a landscape/ portrait photographer... I visited some family in Negril back in December 2007, and while I was walking near the light house I noticed an open courtyard of which over looked the Caribbean sea. I figured this would be a very nice location to capture a few images for my desktop screen.The sky was perfectly clear and I didn't notice any birds in the sky...I sat and waited a few minutes for a cargo ship of which was on the horizon to exit my shot and then I fired off three frames in rapid succession. I always bracket my shots in RAW+ high resolution, and this was no exception... On the screen the images appeared perfect, so I packed up and headed on down the road.It was when I returned home and was going thru my shots that I noticed that there was an unusual "spec" on one of the three images of which I had captured.The image I captured was in the second frame.It drew my attention because my initial reaction was that this ruined the otherwise perfect shot. I think it is more than just a "spec" lol.I sat on this image for quite some time however I did show it to a few of my closest friends joking about capturing a UFO on camera.Initially I saw the first "spec", but several days later after going back to the original image, I realized that there were two of the objects on the shot with the second apparently further away from my post.I have gone over this photo many times and tried to find a conclusion as to what could have gotten into my image but I cannot honestly think of anything that would show like what I have.... I inverted the colors and this was when I realized that the objects were both apparently very far away, large and solid in shape, and must have been traveling reasonably fast. I have been shooting photos for several years, and have many shots with birds, planes,etc in the background... This is a first for me.Regards... *Deleted wit's initials--SGonzalez/CMS.
