Photographers have it easy: They need to catch their subjects looking great for only a split second. Videographers have to capture a good-looking scene for several minutes. Sony helps them out by equipping its newest camcorders with face detection, which finds up to eight mugs and continually adjusts the focus, exposure and color to optimize their appearance.

Shortly after Panasonics announcement, Sony declared that its new models will also have face detection—so the camcorder stays focused on subjects even as they move around. Sonys face-finding models—the high-def HDR-UX20, UX10, SR12, SR11, and SR10 and standard-def DCR-SR220, SR85 and DVD910—track up to eight faces and optimize not only focus but also color and light exposure. And when they compress the video for storage, they allocate more digital bits to the subjects mugs, so they come out looking sharper. Sonys still cameras with face-detection are very adept at locking on the kisser, and the same Bionz image processor tech is now in the camcorders, so results should be good. In a very quick test, a preproduction model found up to four faces (the most I could get in a frame), even those in profile.
