How does lens F-stop rating (aperture) relate to low-light and night performance?
The F-stop rating or aperture of a lens describes how bright the image generated by the lens is as compared to the brightness of the object itself. For example, if you are using a lens rated F/2.0, then the image will be 1 / (2.0^2) = 0.25 or 1/4th as bright as the object. Thus, a l… • Remote Command & Control Protocol Definition for FrogEye and SharkEye Cameras SharkEye and FrogEye cameras can be controlled remotely and images can be retrieved by a host computer. The attached document provides the protocol definition and some limited code samples for control via RS-485 and IEEE-1394 (Firewire). The following architectural approaches may be… • The Care, Service Interval and Product Life of Desert Star Underwater Equipment With proper care and regular preventative service, Desert Star equipment will operate for many years.
