While I was standing in my yard at my residence. I was taking a picture of a passenger jet that was at a high altitude in the air (traveling from my right towards my left or East to West) I saw a small speck/flash of white against the sky, which I thought was another airplane. As I got my camera focused and zoomed in on the object it did not appear to be a regular airplane, it looked more tubular with no visible wings like an airplane would have and it was white in color. I was able to take 2 pictures of it before it left my sight. The object was flying initially a more North to South direction then it turned East towards the horizon. I lost sight of the object when tree limbs blocked my view. After downloading the pictures I noticed that it did not have any features of a regular airplane or helicopter and I could not identify it.
