can anybody tell me the meanging of the orbs that are in the pics i am taking with my new digital camera???? they are not spots on my lens because they don't show up in all my pics like they would if they were dust spots or water spots etc. i'm not too worried but they were in the pics i took at my house, my sister's house but not my brother's house. they were taken in the early evening. i took some pics about 2:30 this AM of different rooms in my house and there were no orbs at all. can anybody help me??
