The glasses can add one foot (or 30.5cm) on to the wearer's normal eye-level. They look, erm, great! IMAGE: Dominic Wilcox This device designed by Dominic Wilcox allows the wearer to see ‘one foot taller’ (30.5cm) than their normal eye level. The single largest use of metal in the iPhone is in the outer frame, so that’s where Apple turned to advanced metallurgy to save some grams and gain some marketing points. Reducing the mass at the perimeter, which the change from stainless steel to titanium has done, has definitely reduced the moment of inertia more than a uniform reduction in mass would have. And that will make the 15 Pro easier to manipulate and will contribute—at least somewhat—to the impression of lightness.” Dr. Drang

This notable achievement is worth celebrating. For the first time, Apple’s keynote discussed repairability: Digital zoom, in its many guises, is just a fancy way of saying a photo is cropped to look like a zoomed image. Granted, digital zoom has come a long way. With high megapixel sensors, "binning" (multiple pixels treated as a single, large pixel), and better upscaling algorithms, manufacturers are getting better results.The big upgrade for the cameras this year is the “tetraprism” periscope lens, upping the iPhone’s optical zoom from 2x to 5x. The S23 Ultra technically beats this with 10x zoom, but the way Apple’s engineers achieved it is particularly interesting.Tetraprism, a fancy way of saying four lenses, is a word invented by Apple’s marketing team, but it’s got a nice ring to it!

For example, a lens with a focal length of 200mm and a maximum aperture of f/2.8 has to have a front lens element that’s more than 70mm (or 3 inches) wide. And that's not including any manufacturing considerations. The biggest limits with photography have always been physical, rather than technological. There are some laws of optics you just can’t engineer your way through. This is why DSLR and mirrorless camera lenses are so big and heavy. To provide long focal lengths and wide apertures, lenses themselves have to be a certain size. You could use a large, flat sheet of sturdy cardboard instead. Lightly score it with a craft knife to divide it into four sections, then fold it into a box and tape together. The 15 is an incremental upgrade, and that’s just fine. The rollout of the 14’s innovative open-from-both-sides mechanical architecture is welcome. Investments in camera hardware are always well spent, and the periscope is particularly innovative. Given the expense, reduced drop test tolerance, recycling challenges, and fragile finish, titanium doesn’t seem like the best long-term material for a smartphone—but we’re impressed Apple pulled it off. We tip our hats at the materials engineers, but aluminum works just fine from our perspective. Dominic Wilcox, a British designer and industrialist, has created the "One Foot Taller" glasses, which are essentially a pair of periscope glasses that let you see over the heads of people in front of you.However, manufacturers are starting to run into problems. You can’t shrink camera sensors much smaller without the trade-offs becoming unmanageable. Small sensors perform a lot worse in low light and have a more difficult time with higher resolutions. Our everyday business is in the international market, and this is not only because we deliver to over 40 countries. For many years we have made it our business to familiarise ourselves intimately with all manner of different regional conditions. I also experiment with materials to try to find surprises that can't be found simply by thinking with a pen or a computer’’ he added.
