The better the photos the better the video!

When we think of a TV commercial we think of video cameras, video and audio, but, many a video commercial contain still photos edited into the script. With the advent of the 4k video camera, resolution is much better than in even the recent past. Digital still cameras, however, still out perform video cameras for dynamic range and detail.
4k (4x 1080p) still is only about 2160px X 1440px or about 3mp compared to a Nikon D90, a 7 year old camera with 12mp of resolution or a newer D610 at 24mp. Even though video can't render such high quality files on TV, the higher quality the starting files the better the result after down sizing.
Here are some shots commissioned by a video house for some up coming TV spots.
