Many of FUJIFILM users who use their camera as a webcam with FUJIFILM X Webcam had lots of complaining, such as you cannot do any setting, white balance, film simulation adjustment...etc during the camera connecting to your computer, so today FUJIFILM also released the new version of the X Webacm 2.0.
Once X Webcam App is updated to Ver.2.0, Launch the X Webcam 2 to open the Settings window, where users can choose a Film Simulation mode, activate the Instant AF, lock AE, or adjust digital zoom magnification, exposure compensation and white balance**.
