New camera ordered

I ordered a new spy camera. Once it arrives I intend to set it up again at the foot of the front stairs. I found the old chips and took them to a processing center to see if I could determine what I was photographing. Unfortunately I don't have the know-how to properly use the facility. The pictures came up on the screen but when I tried enlarging them they cut off a quarter of the picture that had the part I wanted to see. Also I couldn't figure out how to lighten the picture. I know it can be done because an attendant who was present when I did the original picture with the figure walking up the steps beside me, lighten the photo considerably. She was not working the night I took in the other chips. I'll have to make another attempt on the chips later, hopefully when I can get some help. As for the famous stair photo that started all of this. After we enlarged the photo and brightening it considerably I made several copies. We still cannot fathom what the heck the phantom is. It is quite obvious that I am ascending the stairs on the rail side. This is to be expected as I normally use the large handrail when going upstairs. The phantom is exactly beside me on the inside, next to the wall. The phantom appears to be wearing some sort of coverall, not unlike some hospital personnel wear. There is even folds in the leg areas of the "pants". Other than the fact we have established that no "living" person went up the front stairs with me and the strange figure is wearing a type of coverall that no one in my family even owns, we have no explanation for what or who this figure is. I will note, however, that this house served several years (before I purchased it) as a doctors office and then a long period of time as a rest home. Personnel would probably have used the cover all type uniform at various times. My spy camera took almost 1000 total photos while I had it in use. All of those pictures were supposed to have been taken because the camera detected movement. Nothing is seen in most of the shots. What set off the camera? I guess if you really want to drive yourself insane; just set up a spy camera a see if you can figure what sort of "whatevers" are setting it off. You might really be surprised at what develops.
