Webcam tips For optimum performance, observe the following guidelines while using the webcam: ● Be sure that you have the latest version of an instant message program before starting a video conversation. ● The webcam may not work properly across some network firewalls. NOTE: If you are having trouble viewing or sending multimedia files to someone on another LAN or outside your network firewall, temporarily disable the firewall, perform the task you want to perform, and then reenable the firewall. To permanently resolve the problem, reconfigure the firewall as necessary, and adjust the policies and settings of other intrusion detection systems. For additional information, contact your network administrator or IT department. ● Whenever possible, place bright light sources behind the webcam and out of the picture area. Adjusting webcam preferences You can adjust webcam preferences, including the following: ● Brightness-Controls the amount of light that is incorporated into the image. A higher brightness setting creates a brighter image; a lower brightness setting creates a darker image. ● Contrast-Controls the difference between lighter and darker areas on the image. A higher contrast setting intensifies the image; a lower contrast setting maintains more of the original information's dynamic range but leads to a flatter image. ● Hue-Controls the aspect of color that distinguishes it from another color (what makes a color red, green, or blue). Hue is distinct from saturation, which measures the intensity of the hue. ● Saturation-Controls the strength of color in the final image. A higher saturation setting creates a bolder image; a lower saturation setting creates a more subtle image. 10 Chapter 5 HP Webcam (select models only) ENWW
