Critics claim that the resolution is too grainy, but today digital images are equal to film images. Unfortunately the critics are not updated on their digital technology. In most cases, digital images are better and more reliable than the chemical methods of film prints. Almost every major photography magazines now include major articles on digital photography. The digital technology is her to stay and is being acknowledged and promoted by major photographic organizations and schools.
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.
