...Your digital camera may.
For example, looking down (sort of like a tunnel) the space between joists, etc. Sometimes there isn't enough room to maneuver to be able to see.
If your camera has an instant preview feature, that's even better, so you don't have to wait to upload the pictures.
Remember to hold on to the camera!
(There are other devices on the market used for looking into areas that are not easy to reach, but if you already own a camera...)
