LCD Viewfinder Calibration

smpte-arib-bars-sample LCD Viewfinder CalibrationA very common question that comes up a lot in the workshops that I run is how do I check the calibration of my viewfinder? I wrote up a guide to this some time back, so in case you haven’t seen it, here is a link to the post:¬†http://www.xdcam-user.com/2012/06/calibrating-your-viewfinder-or-lcd/

Alphatron EVF uses iPhone Retina Display Panel.

I am hoping to get time to play with the soon to be released Alphatron EVF at NAB. This new EVF boasts a range of pro features and a much higher resolution screen than currently available in the other low cost EVF’s on the market. To get good resolution TV-Logic scoured the world looking for a good, small LCD panel. Anyone with an iPhone 4 or 4s will know how good that display is and that’s the panel thats going in the new viewfinder. The panels resolution is 960×640, but the viewfinder will only use 960×540 pixels so you get easy 2:1 image scaling for 1920×1080 video. There is more information on the benefits of this simple 2:1 scaling on the Alphatron web site.
