In a nutshell, A video light is basically a device that emits a constant light source, something that is different from conventional strobes or flashes. The upside to using a video light is that there is no sync speed to worry about, and thus virtually any shutter speed setting can be used. Due to its constant lighting though, the primary drawback of video lights is that they are usually weaker than flashes that could fire intense amounts of light in an instant.
Another property of the video light is the way it throws the light to the subject in a certain manner, as we can see with this photo:
Note that the light falls in a dramatic way on the subjects; the contrast between the shadows and the lights is not that harsh compared to the contrast direct flashes (without any diffusers of the sort) could give. It gives a kind of subject isolation that spotlights would give to performers on a stage. Lastly, since it's a continuous light source, adjusting the way the light falls on the subject is much easier.
Now on to the photo... This was taken when I decided to tag along with my friend Christian on a casual shoot around the UST campus. I wasn't really planning on doing any serious photography then, so I lent him the video light and simply watched him and his friends snap around the Benavides Garden area (I had my camera dangling on my hip though, just in case). The lights in the background? Christmas season's around the corner, and the school has this habit of setting up lighting decors roughly a month before December strikes. ;)
Oh, and the title itself? Well, those two cameras in the photo are both Canon 7D bodies. It just felt right to find and shoot at them in their respective poses, both holding two similar cameras, as if we're looking at a shot of a Canon advert...
....which was taken by a Nikon camera. ;)
