I was recently flipping through some pictures I took of my trip to Granada, Nicaragua in 2011. In two pictures, I saw what appeared to be strange objects in the sky. Although they appear small, if you zoom in with computer software such as Windows Photo Viewer, you can see these objects take better shape. Honestly, I am not able to answer a majority of the questions listed above because I didn't even notice these objects until now; in fact, the qualities I checked off above only related to the description I was able to get from the 2 photos. I know the date and approx. time of the trip because I checked my passport to see what day I was actually in Nicaragua. Also, I don't believe these objects to be anything on the lens because I took other pictures as well and all the others are clear without anything else in the sky with the exception of birds. The birds that appear in the other pictures are jet black. Also, as you can see, the day was beautiful with a lot of sun and virtually no clouds. I am curious to get some insight as to what these objects may be. I don't buy that they are balloons or weather phenomenon but rather some sort of craft. Also, the pictures were in no way edited and these images were in no way manipulated from the original image. I used a regular Sony point and shoot camera with I believe 10-12 megapixel capability.
