The campaign Clicked with iPhone 6, from Apple, has everything. We have already informed her that she won the maximum prize in the “Outdoor” category at Cannes Lions. One of the images used in the campaign was also awarded (this time with a Golden Leo).
The photo was taken by Cole Rise (photographer and creator of the Litely app) in the Rocky Mountains National Park (Colorado, United States).
Om Malik, Rise's friend, talked to him a little about a debt that many may have: how a photo taken with an iPhone 6 (which already shows imperfections in an iMac with Retina 5K screen) looks so good printed on a giant billboard like the many we saw in this campaign? According to Rise, all magic revolves around dots / pixels per inch.
As we know, the iPhone 6 camera has 8 megapixels, generating an image with 72ppp. It's just that billboards that are large and far from our eyes can use a lower density of pixels per inch (somewhere around 12-15) that still look great. On the other hand, a common 4K monitor (32 inches, for example) usually has a density of 140ppp (almost twice the density of photos taken with iPhones). Thus, the pixels “stretch” and the photo is ugly. On the other hand, if we are talking about a 4K monitor of 60 or more inches, the density already drops to something below 72ppp, leaving the photo beautiful.
