The world of high definition has changed significantly in recent years. The 4k screen resolution or frequently referred to as as ultra high definition and all of its features have become a popular format within the media world. Offering about 4 times more pixels than HD, UHD boosts image clarity, increases frame rate, provides more vibrant colours and improves image depth. Although one of the first 4k cameras, the Dalsa Origin was used in cinematography in 2003, UHD only arrived on the mass market in 2011when cinemas began using 4k projectors. The filming world has seen companies such as RED make accessing the necessary tools to creating quality footage affordable within the filmmaking industry.
One of the first movies to be filmed in 4k was snow white and the seven dwarfs in 1993. Despite capturing the initial footage in this form, it was downscaled to 2k in order to fit the technologies at the time. Now, most of our favourite films such as Interstellar, Gone Girl and After Earth are shot and displayed in UHD through mediums such as Netflix. This technology is broadly used across many devices and gadgets such as cameras, drones and televisions underlining the notion that better picture is attainable anywhere.4k is the future, however the debate about whether the transiting to UHD is advantageous remains. Despite the doubts of many, statistics show that there has been an increase of 17% in the sale of UHD televisions in the UK in the last 2 years alone. The issue many have with this format is that it is not widely used enough to be standardized in the media world, some deem it to be a waste as the visible advance is not as advantageous on smaller screens resulting in an expensive transition to accommodating this technology.
