The reason I chose it is because it is very clear the creative possibilities of having a humungous first plane and a tiny far plane of the same person... Perspective.

This article from Photography life 'focuses' mostly on landscape photography with wide angle lenses: https://photographylife.com/how-to-use-wide-angle-lenses

Dan Vojtěch's article: "Amazing how focal length affect shape of the face" demonstrates how changing your focal length and distance affects the appearance of everything. Pascal Vandecasteele uses the same photo in his article: "How focal length affect the shape of the face".

Shoot a bride from the floor, shoot a sports person from the tip of the hand or feet, shoot an ant eating a dog, shoot some toys next to real people.

Different lenses are useful in different situations. Next time you are out in a forest or field, and come across an enormous mushroom, take a photo from 20cm distance using your 2 lenses, see the effect of the result, and the reason why someone might choose a close-up, wide-angle shot becomes self-evident.

"Wide angles create intimate relationships. Wide angles emphasize the photographer's height, distance, and relationship to the subject. When we look at a wide-angle portrait, the visual cues and exaggerated foreground-background perspectives tell us exactly where the photographer was, relative to the subject, within a broad environment.".

Doing a close-up allows you to use perspective to further exaggerate the relative sizes. The wide angle also allows you to include more context than a telephoto lens, especially at close range to the subject.

My use case slots right in between: I want a larger platform to draft news and reviews and answer secretive emails as I sit in the make-believe comfort of public transit. The glasses are also practical for when your partner wants to watch The Bachelor on the living room TV, but you're more interested in the marriage of basketball and the spirit of competition.

At short focal lengths you are looking around the object and obtaining an in-focus background and with long focal lengths you are looking at a smaller segment from a distance, flattening the object and blurring the background. Of course it's possible to make adjustments to distances to increase or reduce the effects and crop a higher resolution to simulate a closer shot.

From a bystander's view, I look like the mightiest of keyboard warriors, churning out bodies of text without ever needing to look down at the QWERTY layout on my laptop. From my view, I'm staring at a 120-inch display projected two feet in front of me thanks to a meticulous arrangement of light and mirrors within the Viture One's XR Glasses.

The distortion of wide angle lenses allows you to magnify the subject relative to the rest of the frame, leading to dramatic or otherwise interesting compositions.

At the time of writing, the Viture One XR Glasses are selling for $439, and that includes the power adapter, a carrying case, and nose pads at various heights. For the price, I'd recommend these to traveling professionals, gamers, and those who want a more private but accessible display experience. The Viture One XR Glasses won't beat the Meta Quest 3 or Apple Vision Pro, but they bring enough to the table to ease any FOMO you might have as more expensive headsets hit the market.

Ken Rockwell has written a very interesting article about his: https://kenrockwell.com/tech/how-to-use-ultra-wide-lenses.htm

A very good way of using an ultra wide lens is to get really close and get something right in the viewers face. Using a wide angle lens to get everything in the frame often leads to very boring pictures because the viewer has no idea what the photo is about.

I credit that to two factors: the lightness of the wearable compared to traditional headsets and the wearer's ability to retain spatial awareness. Remember, the glasses are not standalone devices with their own operating systems. They're simply an external monitor reshaped into something more pocketable. And thanks to the transparency of the lenses, you'll never feel like you're drawn into another reality when you have them on.

Still, Viture has integrated some clever mechanisms with the lenses, like a self-dimming electrochromic film that you can toggle on or off depending on how bright your environment is. It's basically a built-in projector shade and helps the most when you're using the glasses outdoors.

Viture is pitching its glasses to people who want to game, watch movies, or surf the web without needing to be physically in front of a TV or office desk. The glasses' 120-inch projection is more suited for folks who would rather binge-watch shows while lying in bed or are on a flight and seek privacy when using a phone, tablet, or laptop. But the overlap in use cases is uncanny and not unintentional.

Digital Photo mentor also wrote an article about how to use wide angle lenses: https://www.digitalphotomentor.com/5-mistakes-beginners-make-using-a-wide-angle-lens-and-how-to-avoid-them/

As @Agent_L says in the comments, if you take photos with your 2 lenses at exactly the same short distance from something, the answer to your question becomes more obvious. If you are curious about this - and you must be, since you asked here - then you should simply take the photos and see for yourself.

Viture partnered with Harman to develop and tune the side-firing speakers of the wearable, and I'm impressed. They remind me a lot of bone-conduction headphones where audio beams against the side of your head and into your ears. Since the speakers are lying against you, no one but you can hear the audio output, which adds to the privacy focus that the company is going for.

To get a close-up of something with a wide angle lens, you need to get extremely close. Everything seems about 3 times further away in the picture due to the focal length, so you need to get much closer than 50 cm to get something really close.

As I make my way to the back of the commuter bus, I pull out what looks like an ordinary pair of sunglasses (with only slightly thicker frames), connect its MagSafe-like power adapter to my MacBook, sit, and start to click, drag, scroll, and type.

I have a Samyang F/2.0 12 mm for the Sony E Mount, so the 35-mm equivalent focal length is 18 mm (crop sensor 1.5×). I use it mainly for landscapes and architecture in order to fit more in my frame than I can with my other lens, usually focussing close to infinity (I also use it for photography of starry nights such as the milky way or star trails, as it is also by far my fastest lens). I sometimes use it in small indoor spaces, with a focus perhaps down to 1–2 metre at the lowest. But I've never used the lower half of the focus ring, which includes focus down to 20 cm. When I want detail, I tend to use my zoomlens (18–200 mm). Under what circumstances would one use a wide angle lens with a focus less than (say) 50 cm?

Of course, there's no standard of spatial video playback quality for me to compare with, but based on what I saw, the essence of the format was there. I could see the separation between the subjects in the videos, and that remained consistent so long as my camera was well-distanced and in focus.

Perhaps the biggest question with such wearables is whether or not they cause symptoms of dizziness and motion sickness. From my experience, which includes one- to two-hour stints, I never felt discomfort when using the glasses.

Here's the killer feature of the Viture glasses: spatial video support, the same 3D playback capability as found on the Vision Pro. While an adapter is necessary for the glasses to pair with an iPhone, the company has developed a new SpaceWalker app on iOS that lets users watch spatial videos recorded by an iPhone 15 Pro or Vision Pro. I played a couple of clips that I had previously reserved for the Apple headset, and reliving those moments with such depth and realism was quite eye-opening.

To me, the photos with the zoom lens appear more interesting for this purpose. The bokeh is stronger (even though all photos were taken at F/8.0) and the object fills more of the frame. What possibilities does an ultra-wide lens offer when I focus on an object that is close by?

"The shorter the focal length, the closer to the face. That is why the nose looks bigger in the 20mm lens shot than in the 200mm lens shot. If all photos were taken at the same camera distance, the face would look the same for each lens, however, the head size would change – smaller for the 20mm lens gradually getting larger up to the 200mm lens."

That seems to be unavoidable due to how large but close the projections are to your eyes. For example, if you hold an object an inch from your eyes, you'll notice how difficult it is to focus on it.

I found the best way to calibrate this was to keep the opposite eye closed as I was tuning each side. However, finding the perfect focus will take some trial and error, and even when you think you've struck the right distance, the corners and edges of the 120-inch projection will remain blurry.

For a longer explanation (and female models) check out JP's Slanted Lens video: "How Lens Focal Length Shapes the Face & Controls Perspective: A Lighting Tutorial".

This almost sounds like the Vision Pro dream that only a few experience, but it's achieved through a $439 wearable, not a front-heavy headset that costs an arm and a leg.

I have modified the animation offered on Dan and Pascal's pages to slow it down, and repeated the first and last frames at an even slower speed to demonstrate the difference:

In the example below I took different photos of the same object, first twice with my Samyang 12 mm prime lense, then three times with my Sony E 18-200mm zoom lens, at various object and focal distances. I downsampled the images from 4000 to 1200 pixels wide but otherwise did not do any other post-processing than in-camera processing. The candle holder is about 9 cm high and 12 cm wide.

Probably the best comment comes from Em Jo Photo on DPReview's webpage: "Facial distortion of various focal lengths for headshots":

Thanks to the single USB-C cable needed to power the device, I can easily pair the Viture glasses to my MacBook or Android phone. Bonus points if the latter is a Samsung Galaxy that supports DeX mode or a Motorola handset that supports Ready For; in those two platforms, you'll be greeted with a desktop interface of your usual mobile apps and services.

Instead of transmitting you into a virtual or augmented reality like Apple's Vision Pro, the Viture glasses simply extend from -- and are powered by -- the source they're connected to, serving as an ultraportable, on-your-face monitor. To be clear, comparing the XR Glasses to a $3,500 productivity wearable is an apples-to-oranges affair. Unless you consider yourself an early adopter, the target customers of the two gadgets are notably different.

As far as the visual experience of the glasses goes, it's adequate, but nothing groundbreaking. For prescription wearers like myself, there are two Myopia rotary knobs (think focus dials) on the top of the Viture One that can be adjusted to your vision. That means you don't have to, and shouldn't, wear the XR glasses over your existing pair. You also don't need to fork up $150 for tailor-made prescription lenses like you would with the Vision Pro.
