Experimenting with 4K

Still from a 4K test (4096 x 2160 pixels) - Sale Water Park
Just as the TV/video industry at a semi professional level started to cross from Standard Definition to High Definition a few years back, even before there were many Blu-Rays and HD TVs on the market, the industry is on the move again, starting to make the crossing to 4K (sometimes known as Ultra High Definition). The main (4096 x 2160 cinema standard) 4K format operates at slightly more than 4 times the image area of HD although there is another standard which is exactly 4 times, called the Quad Full HD.
Sony are one of the first manufacturers to release a 4K affordable video camera (the PXW-Z100) which came out a couple of months ago. 4K TVs are few and far between and expensive. There are no Blu-Ray equivalents to play the 4K material as yet, which is limited to computer screens at lower resolution (there are expensive 4K computer monitors) and YouTube which does now accept the full 4K, or straight HDMI link between camera and TV to play to a 4K TV.
For the progressive videographer, we felt that we should try the 4K format out, knowing that with time it could become the norm and in anticipation that more forward looking clients may wish to start filming in that format now.
We have made one or two short test films which can be seen  on our YouTube channel. We have not attempted to go for the beautiful scenic stuff that will show off the film to its best, preferring to shoot almost anywhere, under winter conditions when lighting is not so good. If you would like to see what we have done so far experimentally, see below.
