p.1 #2 · p.1 #2 · Will High-Res Video Capture Make Still Photography Passe? | |
I think it will happen rather quickly, but not the way you suggest.
Video cameras (for bradcast) or optimized for... video! Which means that they do a lot of image to image compression and "shutter speed" is optimized for image brightness, not freezing the motion. And with 4K cameras this will get worst (more compression because of bandwidth requirements and higher "shutter speed" because of smaller pixels on the sensors). There will clearly be some improvements as time go tho.
That being said, there have been some video cameras out for a while not that shoot in RAW (no image to image compression and lossless compression on individual frames) and on some of the very expensive models (think Red) you have total control on the exposure parameters. But the price point for these (and the complexity of use) puts them out of reach of most people.
What I think will happen is that the photo cameras will evolve to allow much higher frame rates (bursts) with all the IQ and control that we currently enjoy in the top of the line DSLR's. In a DSLR, the major limit to high frame rate is the mechanical stuff (mirror and shutter movement). If you take these away, your limit is then how fast you can reset / empty your sensor, process the data and put it into memory (buffer or memory card).
Today, as seen in the Sony A7 full frame series, getting rid of the mirror has been done. Getting rid of the mechanical shutter is another story. Why? There are many articles on the web who can explain it better than I can, but the short story is that you'll need a sensor where you can "reset" and freeze the image on all pixels at the same time (or within a very short amount of time). This "global shutter" is still a challenge for high mega pixel cameras (see here for more information on global shutter).
But I am sure we'll get there soon!
