The human eye may hold the fix for self-driving cars

Gizmag news -

In today’s world, more and more daily tasks are being fully automated. Robotic devices can work independently, and they are often more efficient than humans. Yet, in some aspects, technology still cannot match what nature has created. One example is vision. Advanced cameras are used in modern robots and self-driving cars, allowing them to detect and recognize objects quickly and accurately, but there is one thing with which they still struggle: sudden changes in lighting. A research team from Pennsylvania State University may have found a solution.

Leica SL3-P sample gallery: how race-ready is Leica's latest?

Looking for an original take in a scene set up by Pat Domingo, I asked the model if she could get into the driving seat of the car on the set. I wanted to see how much of the huge strobe outside would make it through the narrow windscreen. I asked her to look forward, as if driving, then turn to her right, as if something had caught her attention. This is the moment she did.

The launch event for the Leica SL3-P included not only the chance to get trackside at the famous Nürburgring motor racing circuit and a studio setup by fashion photographer Pat Domingo but also the presence of famed photographer Steve McCurry.

This meant I found myself in the frankly ridiculous position of asking to shoot a portrait of one of the world's most famous portrait photographers, as well as the more familiar challenge of trying to find a unique shot in a pre-staged studio scenario.

Included in the gallery are a handful of shots taken with the new 50mm F1.4 and 100mm F2.8 Macro lenses.

Here's Leica SL3-P (and I) got on:

The creative camera choices behind one of the year's biggest music videos

Digital Photography Review news -

Since it was released two months ago, Olivia Rodrigo's music video for the song "drop dead" has already garnered 42 million views. There are probably a lot of reasons it's been so popular: it's the lead single for a very popular artist's new album, was shot on location in Versailles and clips from it have been popular on social media sites like Instagram. But the aesthetic of the video probably helps too; it has a dreamy, old-school look to it that taps directly into 90s VHS nostalgia.

While that's well-trodden ground for modern music videos, the effect is very convincing... because it's real. A recent video from the YouTube channel Frame Set goes deep on how the video, directed by Petra Collins, was shot, in a wide-ranging interview with its cinematographer, Todd Banhazl.

The interview also covers how the team captured the dreamy, undercranked effect used in the striking opening scene.

The video obviously covers the mix of cameras used, going into why the crew chose to use BetaCam, VHS and MiniDV, and the different situations where they needed to go with one over the other. There are plenty of interesting details in it for camera nerds, but it also doesn't slack on discussing craft; a lot of the video is focused on the interesting lighting setups needed to film in a historic building with limited control while using cameras with very low sensitivity.

It also touches on other technical aspects, like the difficulties of editing interlaced footage that will eventually be shown using a platform designed for progressive video, and deeper topics like the rise of the lo-fi aesthetic in the age of AI-generated imagery. Even if you're not into music videos or Olivia Rodrigo's brand of pop-rock singer-songwriting, the interview is well worth a watch just to see a clearly talented creative talk about their process.

Volkswagen California camper van gets cooler than ever ... literally

Gizmag news -

Just two years ago, Volkswagen launched a new California, but the iconic camper van is already up for a refresh. Along with the Multivan underneath it, the California gets a new look, sharpened interface and improved driver-assistance package. Best of all, a new climate control feature promises to make camping more comfortable throughout the entire year. Combine all that that with existing features like an available PHEV powertrain and indoor/outdoor kitchen design, and we'd say Volkswagen has quietly introduced the best California ever.

China aims to generate world’s blackest car via hybrid nano-tech paint

Gizmag news -

Chinese scientists have discovered a way to combine high-tech light-absorbing nano-technology with more conventional water-based carbon pigment spray to coat car bodies with a durable ultra-black finish. The result is a black that creates a ‘black-hole’ effect of virtually no reflected light at all.

We put Nikon's updated and lighter-than-ever 70-200mm F2.8 to the test

Digital Photography Review news -

Earlier this year, Nikon introduced a new version of one of its professional workhorse lenses: the Nikkor Z 70-200 F2.8 VR S II. We've now had the chance to spend some time with it, shooting portraits, firefighting aircraft and more. You can jump straight to the gallery to see the results for yourself, or read on to see what we thought about how it feels to use and the images it produces.

In Use Three of the Z 70-200mm F2.8 VR S II's states. Left: its smallest and lightest configuration (998g / 35oz). Middle: the lens with the cosmetic bayonet cover (1028g / 36.3oz). Right: the lens with its foot and hood (1248g / 44oz).

The big (or rather, not so big) selling point of this lens is its size and weight. Without the tripod foot and cosmetic sleeve installed, it's only 998g (35.2oz); the lightest full-frame 70-200mm F2.8 for a mirrorless system. With that said, I typically preferred to use it with the tripod foot; it's Arca-Swiss compatible, making it very easy to mount to a tripod, and the lens isn't quite light enough that I feel terribly comfortable toting it around without a solid handle to remind me that I'm carrying a camera attached to a lens, not the other way around.

Even with the foot, the lens’s weight is competitive with that of its lightest competitors, and is a substantial improvement over the original. The lens's center of gravity is also remarkably consistent as you move through its zoom range, so you don't have to shift your grip as you change focal lengths.

The tripod foot and decorative bayonet collar are toollessly removable using a button and a bit of a tug.

In terms of features and controls, this lens has most everything you could want, with the exception of the top-display from the previous generation that some – though not I – may miss. And as someone who has long disliked clickless control rings, it's good to see Nikon providing the option to click or declick the one on this lens, even if I’d still personally prefer a dedicated aperture ring.

I also appreciate the ample number of function buttons, which are available no matter what orientation you're holding the lens in. The manual focus and zoom rings are also satisfying to turn, and the latter is a relatively short throw, letting you move through the range quickly if need be. While the pattern on them provides plenty of grip, I do wish they were just a bit softer, but not enough that I'd be willing to accept any trade-off in durability.

The tripod collar can be freely rotated, making it easy to switch from portrait to landscape, even when mounted on a tripod. I do wish it had detents or clicks at 90° intervals, though, as those make it easier to tell when you're perfectly aligned.

Nikon says the lens has an upgraded autofocus system, and I found it always kept up with the camera, snapping into focus very quickly. It never felt like the lens’s autofocusing motors were bottlenecking the body, or like I would have gotten a shot if only it had moved a bit faster.

When working in concert with a stabilized sensor, this lens's optical stabilization is among the most impressive that I've used in a full-frame zoom. It's so effective, in fact, that it can occasionally be a bit difficult to precisely recompose your image with it on, though I only really noticed that in a few situations.

Optics

With the lens wide open at F2.8, there's noticeable vignetting at the corners throughout its focal range (though it's most noticeable at the long end). It mostly clears up by F4, though you'll see further improvements going to F5.6. While this can easily be corrected using the lens's profile, this will come at the cost of having fractionally more noise visible in the corners of the image.

You can gain a small sharpness advantage in the corners by stopping down, too, but in our experience, this lens is very sharp corner-to-corner no matter what focal length or aperture you're shooting at.

70mm F2.8 F4 F5.6 F8.0 200mm F2.8 F4 F5.6 F8.0

I find the lens's bokeh to be very pleasing, rendering even busy backgrounds relatively smoothly. The specular highlights are also quite clean, without distracting aberrations, which is exactly what we'd want to see in a professional lens destined to shoot a lot of weddings with trendy lighting.

Nikon's latest coatings are also quite impressive. There was one time when I was shooting pretty much directly into the afternoon sun, which produced a somewhat washed-out image, but things improved as soon as I was shooting even a little off-axis.

1 2 3 Even with the sun directly outside of, or even in the frame, the lens was able to hold onto a fair amount of color and contrast.

The lens makes use of minor software corrections for geometric distortion – there's a very mild amount of pincushion distortion at the long end and barrel distortion on the short end – but we wouldn't consider using them mandatory. And, indeed, neither does Nikon; with the 70-200mm F2.8 VR S II attached, the camera allows you to turn off Auto Distortion Control, which isn't the case with every Z mount lens, such as the Nikon 24-120 F4 S.

High-sensitivity electro snout sniffs out unsafe food

Gizmag news -

Though most human noses can detect suspicious smells at relatively high levels, they're not always able to discern every single scent. Researchers from the University of California - Berkeley, however, have developed an “electronic nose” that can pick up on the gases emitted by expired food or food allergens which they claim is “better than human noses.”
