Digital format has some benefits over film format that skeptics refuses to acknowledge. First, the image can be viewed immediately so the location of the ghostly anomaly can be confirmed and focused on with other cameras and instruments. Second and most important, images are already in jpg format and suitable for uploading to the Internet. These images do not need to be scanned into the computer as film images require. A film camera is not IR sensitive and was not designed to pull from the IR spectrum, so Digital is more designed for this research than film.
Orbs are Infrared.
I recommend without reservation the use of digital cameras for conducting field investigations of haunted sites. The digital camera and the new digital camcorders are the wave of the future. Today's critics are tomorrow's supporters. The digital format is the future today. I love the digital camera and is so nice to be able to download the images immediately and view the results on the computer.
