UHD

New Zealand D-Photo - - EXPLAINED UHD -

We take an in-depth look at the lat­est buzz­word in tech — ul­tra high def­i­ni­tion — and en­list HP’s new star, the ZBook Stu­dio G3 Mo­bile Work­sta­tion, to see what it of­fers image edit­ing.

‘Ul­tra high def­i­ni­tion’, more com­monly re­ferred to by its snappy short­hand, UHD, is the next step up from ‘ full high def­i­ni­tion’ (full HD or FHD), the of­fi­cial name for the dis­play res­o­lu­tion 1920x1080 that has dom­i­nated our screens for the past decade. Set to re­place full HD as the high­est-res­o­lu­tion op­tion avail­able for con­sumer-grade screens, UHD bet­ters its pre­de­ces­sor four-fold, of­fer­ing a mas­sive 3840x2160 pix­els. Add these pix­els one by one, and you’ll end up at an as­tound­ing 8,924,400. 4K pro­fes­sional pro­duc­tion and cinema stan­dard. The idea was to re­place the now very fa­mil­iar pho­to­graphic term ‘4K’, but that lasted less than a day, as Sony an­nounced shortly af­ter that it was go­ing to amal­ga­mate the two terms, call­ing the tech­nol­ogy ‘4K ul­tra high def­i­ni­tion’.

Sony’s us­age seems to have taken hold — and across the pho­to­graphic and video-imag­ing in­dus­tries, you’ll of­ten see the con­sumer stan­dard UHD used in­ter­change­ably with the pro­fes­sional nu­mer­i­cal short­hand, 4K, as lead­ing brand names seek to cover all the buzz­word bases — if, per­haps, at the ex­pense of brevity.
