nonphototechnical

Nonphototechnical refers to something that does not involve or rely on photographic techniques. This term is often used in contrast to phototechnical, which describes methods or processes that utilize photography. For instance, in scientific or industrial contexts, a nonphototechnical analysis would be one that does not employ photographic imagery or methods to gather data or reach conclusions. This could include techniques like chemical analysis, mechanical testing, or direct observation without the use of a camera.

The distinction is important when describing methodologies or the nature of certain equipment or processes. A nonphototechnical sensor, for example, would be one that detects physical phenomena through means other than capturing light, such as thermal sensors, ultrasonic sensors, or magnetic field detectors. Conversely, a phototechnical approach might involve using a microscope with a camera, satellite imagery, or other forms of visual documentation captured through photography. Understanding this terminology helps to clearly differentiate between optical and non-optical or photographic and non-photographic methods.
