For the record There are a number of reasons why you might want to capture your images on film. First of all, looking through a borescope for long periods of time is tiring, while viewing images on a video monitor is easier on the eyes. Second, it allows several people to look at the image at the same time. It also generates a permanent record of your findings, which you can then reproduce, distribute to other locations, and even convert to computer files. Although in the past borescopes have been used mainly for direct visual inspection, improvements in image resolution, light sources, and camera sensitivity have made it much more practical to record your images for future reference.
Video capture is most common, but still photography is also used on occasion.
There are two methods for acquiring photographic borescope images. One is to use a video system that allows you to hook a video adapter and camera to the eyepiece of the scope. Naturally, this type of scope is much more expensive than ordinary rigid or flexible scopes. Borescope prices can range from a few hundred dollars for a very simple rigid scope with a flashlight attachment, to tens of thousands of dollars for a complex videoscope system. The good news, according to Habermann, is that prices are not going up, and some of them are even coming down, so that you get more for your money today than ever before.
