I agree they do seem like dust orbs. Looking forward to seeing the other stair picture you took where the cold spot is as well those you have yet to take. Keep trying and as Nakis has said just because you have not captured something on film does not mean something is not there. My bet is you will capture one.
I think I may have gotten one - hubby and I went on our first ghost hunt last night (it was fun and quite intersting). When I figure out how to upload into the computer (new camera) I will try and post a cpl pics. We also had a tape recorder with us. I wish I had a way to enhance the tape as there is a spot that you can hear whispering and it was recorded at the same time as when we took the pic that has something on it. I will tell more when I post later. Our ghosties have been quiet the last cpl days in the household so haven't had any pic opp's here yet but I have camera ready.
Good luck with your picture taking. Between all us newbies at picture taking if we keep going we are bound to get one.
