While on a sight seeing drive in the mountains of Colorado on 09/12/2015 with my wife and step-daughter we stopped at the Twin Lakes area to shoot some photos and did not notice anything strange until I got home and was looking at the photos. When I first looked at the photo in question, I thought to myself, what is that object in the upper right corner of the photo, because I did not notice anything when taking the photo or anything while sight seeing in the area. I have always been interested in UFO's and always wanted to witness one for myself, so I was disappointed that I did not see the object until I got home. I looked at the photo very carefully and did some adjustments to the photo because I always take photos in JPEG and RAW, so I am able to make adjustments with the RAW format photo. I could never get the object in the photo to become very clear, but could see some small details that made the object appear round in shape and dark in color. I thought that since the object was not clear that it must have been far away from where we were when I took the photo. It was a bright day and I had the camera aperture set at F3.5, ISO set at 400, resolution set at 6016 X 4000, and lens set at 22mm. With these settings the camera automatically set the shutter speed at 1/250 seconds, so the shutter speed was fast enough to stop the object. None of the other photos taken in the area had the object in them.
