As to seeing UFOs, there are several things at play, and the most important rule is there are no rules. You have to remember that everyday people go about their lives with their eyes on the busy world around them-watching traffic, store signs, talking on the cell phone, listening to the radio, watching television, and more. It is very rare that anyone really looks into the sky to see if there is a UFO there. We have all seen the unusual phenomena of when one person starts looking up to the sky, everyone around will soon be doing the same thing. Going about our everyday business, we never look up unless we see someone else looking up. Very few people actually are looking for UFOs. And if you saw a person walking around the mall parking lot looking up at the sky, well... you might call the men in white coats in. Skeptics do have a rule they often follow-it is quite normal for a person to make a UFO report, but when that same person starts making one after another, that person can't be trusted, and their reports can be summarily discarded.
As to the photographers themselves, unless there is that rare individual who is specifically looking to photograph a UFO, even a person taking pictures is pretty much watching the subject of his shot, and when you look through the lens, everything is much smaller, and an object in the distance would usually not be seen. It is true that the new digital cameras see better than the human eye in a sense, because the camera is not distracted by sounds, or confused by reflections, shadows, or other movements that are seen peripherally by humans. It only takes a photograph of what falls within its range. This applies primarily to day time settings, and night time photography is even more difficult. Of course, some digital cameras have all of the normal photographic adjustments on them, and depending on how they are set, they can take a photograph of a distant object that is moving extremely fast without blurring. There are also some inherent problems with digital cameras as to reflection and glaring that is beyond my scope of knowledge, but these difficulties only add to the debunker's cache of weapons.
