When we shoot a video, we must want to see how the video looks. But there is a problem. How to look at it in a 1:1 viewing environment? In other words, one pixel in the footage file equals one pixel on a screen. It is pretty easy to do when you edit after shooting but take some extra steps while shooting.

The director of photography will often walk over and double-check that the shot is meeting the technical requirements for focus and exposure. It is very easy to find the hidding flaws in the video signal of the the LCD and built-in viewfinders of even professional cameras.


Your camera likely includes an HDMI port that’s capable of sending out a high-quality digital signal. You can connect this port to a computer display, television, professional monitor, or electronic viewfinder to see what you’re shooting on a larger or higher-resolution screen. This makes it much easier to judge focus and exposure.

Many computer monitors and television sets also have HDMI port. It is very convenient to use an off-the-shelf computer display or television for a relatively low price. You could see your image on a screen that is larger than the camera’s LCD. But you may also find the color exposure of these screens are not 100 percent accurate. They do help us to have a better than the camera’s LCD.

There are many professional photographer who purchase a dedicated field monitor for DSLR video worflows. The size of the field monitor is usually 5-10 inches with lightweight. Company like MustHD, Ikan and SmallHD offer high quality field monitor.
