I've only heard a term for this in one location, but it works well: "short-sided composition." It's from the Story & Heart collaborative community of filmmakers on Vimeo, and it's from this tutorial. I did a quick Google search just now and saw it come up in a few other places; this looks like a good resource with examples from Drive and The Social ...


This depends on the make and model of lens. But often 'HD' means it is specifically designed for recording HD video. So features will often include: power zoom fast focusing, and focus tracking image stabilisation smooth aperture changes quiet operation Not all of these features will apply for every HD lens. Though optimised for video, some of this ...


What does it mean when 'HD' is printed on a lens? Excellent question. My answer: Absolutely nothing. We all know what "HD" stands for, but what does it mean with respect to lenses? Well, there is no consensus among manufacturers as to what the "HD" label means. They are free to put a "HD" label on any lens they want (and they do; many cheap add-on ...

There is a copy of the press release for the lenses here. ...


Whether this is where you found it or not, the definition you give for "Unity Gain ISO" comes from the Clarkvision web site's section on digital sensor performance. As an updated version of that page explains, it's a silly concept. To quote: The fundamental reason Unity Gain is not relevant is because the sensor in a digital camera is an analog system, ...


Unity gain is such ISO number at which camera outputs pixel values roughly equal to numbers of electrons in cells. Native ISO is such ISO value at which the maximum number of electrons in cell is matched to saturation point. It is almost always division instead of multiplication for sensors with big enough electron capacity per cell. Native ISO is as unique ...
