I had been taking a series of photo's from Tobermory to Lions Head Ontario, of an unusual looking cloud or plane trail formation. I took pictures on and off for the hours drive there. When we arrived at Moore St., my husband and I went into the building together. During the time spent there, I was feeling ill, so I excused myself and went back to sit in the truck. Before I went in the truck, I looked up at the remaining unusual cloud formation and thought why not take another picture. I took the picture, looked at it, noticed the sphere in the picture and proceeded to take a second picture, and the sphere, was not present, in it. I don't know if this is a camera thing or a real orb. I would like to know as I keep my eyes to the skies all the time, but have yet to see anything until today in a photo only, not in person. I am submitting all the photo's I took of the cloud formation to show you why I thought it was unusual, the photo of the sphere in the tree is the second last one I believe in the sequence taken. I have 35 pictures in total following the cloud/plane exhaust formation? Taken over an hours approx. length of time.
