5. High quality sets

With every generation of picture improvements comes higher production values. Long gone are the days of the Fawlty Towers sets that nearly fall down whenever a door slams shut, or Dallas window backdrops that were clearly painted by school children.

Filming in 4K means there's no room for shortcuts in scenery

Check out the window on a 4K TV set. Even standing on the set, the window is convincing.

Looking up close, only the set furniture gives the game away.

When every detail shows, you have to get every detail right

To pull off this look requires extremely high resolution photography.

It also takes superpowered backlighting which can be dimmed and coloured to give the illusion of daylight or dusk.

Backlighting is carefully controlled to create the passage of time

We had a walk around one of the sets for the forthcoming Showtime cable drama Masters of Sex starring Michael Sheen. It was the nicest house we've ever been in, yet it's built on the same soundstage where Wizard of Oz was filmed in back in 1939. Sadly, we weren't allowed to take pictures on that set, so you'll just have to watch the show.

6. Sony's professional OLED monitor

Sony's 4K sets make use of the company's super-awesome professional grade OLED monitors for displaying footage in all its natural splendour. The F86 camera can output several different video channels so that different members of the crew can tune into different feeds. The cinematographer needs to be able to see the natural lighting, whereas the camera operators might want to view the footage with different contrast setting so they can see exactly how much detail is being captured in the dark areas of the picture.
