Want to make earthquake-resistant buildings? Try butterfly wings

Gizmag news -

When you hear about designers biomimicking butterflies, your first thought is probably about creating remote-controlled flying toys or small, artificial flying machines that could be useful in pollination, especially in regions experiencing bee colony collapse. But butterfly mimicry goes far beyond those uses to include scattering light to replace toxic paints or as an anti-fraud mechanism against counterfeiters, advancing optical computing, and even creating superior eye implants.

For the latest Question of the week, we were curious to know what your favorite photography-related books and articles were. You took the idea a step further, not just listing titles but explaining how the works you read elevated your photography.

Some of your reasons were purely artistic, with many art-focused books suggested, while others were quite technical. Reading through your responses, it became clear that photography isn’t just about mastering a camera. Many of you shared personal stories of inspiration or creative struggles, showing that the right book or article can spark a change in vision as much as technique.

Check out the top book and article suggestions below, and then let us know in the comments what your favorite photography-related books and articles are.

Your book and article suggestions

"Mountain Light" (1987) book cover

Ruby Rod: When I was a kid, just getting started with photography, my mom brought home a book from a library or a garage sale, "The Fun of Photography" by Mario Scacheri. It's a bit corny and not as politically correct as it is today. The book gave practical advice on the basics of composition, darkroom work, and other aspects of the photo hobby at the time. I still use much of the advice today.

Don Sata: "The Photographer's Eye" by John Szarkowski. This is an old book that is as good as the day it was published. It clearly explains something that took me years to understand, that seems to be an ineffable mystery: what exactly is the language of photography, and how to use it?

Something I also love about this book is that it doesn't discuss any technical aspects of photography, which makes it timeless.

Gayle159626: Years ago, when I was in my 20s (I am now 66), I was gifted an interesting book called "A Day in the Life of Australia" by Rick Smolan. This book is the result of one of the most unusual projects in the history of photography. On March 6, 1981, a hundred of the world's greatest photojournalists were given the unique and challenging assignment of their careers – to capture an entire nation on film in a single day.

"Day in the Life of Australia" by Rick Smolan (1982) photograph collection

On the pages of this unusual diary, you'll wake up with camel hunters in the Northern Territory, visit with prisoners inside an Adelaide jail, see Ayers Rock from outer space, travel through aboriginal missions in Arnhem Land and explore an entire community living underground at Coober Pedy.

The book features 367 stunning photographs chosen from the 96,000 shot on March 6, and includes six special photo-essays exploring a day in the life of unusual Australians. A Day in the Life of Australia is a slice of history – a moment frozen in time.

To communicate what you saw, you needed to translate the lost dimensions (depth, movement, and color) into your photograph.

Klaus dk: "Total Picture Control" by Andreas Feininger. His main message is that the photographer transforms a moving, three-dimensional world of color into a frozen, 2D (and, in the late 1950s, monochrome) picture. To communicate what you saw, you needed to translate the lost dimensions (depth, movement, and color) into your photograph.

With today's endless possibilities for manipulation, he looks like a purist, but he describes the techniques available for the creative photographer to get the message through.

paul13walnut5: As I progressed into video, the book "War Junkie" by Jon Steel really inspired me as well. Talk about calm under fire, until he wasn't... not to spoil the book. It was also a frank confessional at a time when it wasn't really all that cool to talk about mental health.

"The Photographer's Handbook" by John Hedgecoe (1982) handbook

Gato Amarillo: Like most people of a certain age in the US, I grew up on Life magazine with photo reporting, some of it very tough reporting, from all over the world. I think the book that made me aware of photographers as individuals was Edward Weston's Daybooks. That got me thinking about the people behind the cameras and looking at the names under the photos.

Lensmate: "The Photographer's Handbook" by John Hedgecoe was my go-to reference that helped me develop my understanding of photographic techniques back in the 80s.

In the 1990's, the images in the magazine "Outdoor Photographer" drew me into 4x5 photography and gave me a perspective that I eventually applied to my own compositions.

Digital shifting and stitching became the cornerstone of my landscape and architectural photography, replacing my 4x5 film camera. I began experimenting with it in 2011 and was applying it regularly by 2013. I discovered the method online, but I don't remember where. It was probably at Photo.net, but it could have been here. It would be nice to know.

"Jungles" by Frans Lanting (2000) image portfolio

Ctesiphon: "Jungles" by Frans Lanting. Before reading it (do you say "read" for a book of photos?), I thought nature photography (be it macro, wildlife, or landscape) was about capturing nature in the sharpest, cleanest, most detailed, highest-definition images possible. This book completely changed that for me: it is a masterpiece of not-so-in-focus and grainy pictures that let transpire so much more emotion, mood and atmosphere because of it. You can feel the damp air and hear the birds and insects in these images.

It gave me a new appreciation of moody images (for lack of a better word), which I often try to recreate in areas beyond nature photography. And I don't care about noise in my pictures anymore.

Photographs are like gems: the real and the synthetic are often physically indistinguishable, but there is no question as to the ultimate value.

Astro Landscapes: Despite being decades old, I am still stunned by the current relevance and creative inspiration of Galen Rowell's "Mountain Light". As an adventure landscape and nightscape photographer, one quote of his has stayed with me for almost as long as I've been into photography:

"Photographs are like gems: the real and the synthetic are often physically indistinguishable, but there is no question as to the ultimate value. A photograph that depicts a moment of real life, whether that of a human activity or of the natural world, is of a higher order than the most perfect replication created by or for the camera with luck removed from the formula." - Galen Rowell, 1986

The sub-2 hour marathon, and the technology that made it possible

Gizmag news -

For decades, the idea of a sub-two-hour marathon occupied a near-mythical place in endurance sport. Like Roger Bannister’s four-minute mile, it represented a physiological and psychological frontier that seemed just beyond human reach. That barrier finally fell in an official race at the 2026 London Marathon on April 26th, when Kenya’s Sabastian Sawe ran 1:59:30, followed moments later by Ethiopia’s Yomif Kejelcha in 1:59:41.

Viltrox's latest lens doesn't sacrifice quality for value

Last month, Viltrox announced the AF 55mm F1.8 Evo, one of its first lenses to use an apochromatic design that's meant to reduce chromatic aberration. We've had the opportunity to test it out in a variety of scenarios, to see how it performs and, of course, to get samples for our readers to enjoy.

Impressions

As we've come to expect from Viltrox's lenses, the 55mm F1.8 is quite well-built, feeling nice to use without being overly bulky or heavy. At 370g (13.1oz), it's roughly middle-of-the-pack when it comes to mid-range 50mm F1.8 lenses, and it's relatively easy to tote around town, or in a sling bag.

[TK lens photo]

I enjoyed the fact that it had a physical, clicking aperture ring, rather than a command dial, like the one found on the higher-end Lab lens that I recently tested. While it has an "A" setting that allows the aperture to be controlled by the camera, it can't be locked into or out of it. And while I didn't find myself knocking it out of A mode too often, or accidentally changing my aperture setting, it did happen every so often. My coworker Abby also recently had this issue with another Viltrox lens.

The lens also features an AF/MF switch and a programmable button, both of which are nice to have. The manual focus ring feels nice, but at least when paired with a Nikon Z8, it didn't quite give me the level of precision that I'd usually hope for. Likewise, the AF performance was just okay; the lens is quick and quiet, but, as we've experienced before with Viltrox lenses on Z-mount cameras, I just didn't quite get as many keepers as I'd expect to had I been using a Nikon lens.

One last odd quirk: the rear lens cap that came with the lens fits very loosely, as do the Nikon ones, and there were several cases where it came off in my bag. This didn't translate to the lens feeling loose on the camera at all, though; it never disconnected from the actual body when I was turning the aperture ring or otherwise manipulating it.

With that said, the majority of my photos were still in focus, and I was quite pleased with the results. They're sharp corner-to-corner, even wide open, and Viltrox has delivered on its promise to seriously reduce chromatic aberration. I also found the bokeh to be quite pleasing. While it does a nice job rendering out of focus specular highlights, I was actually more impressed by how it rendered the background in portraits I shot at F1.8.

Something about the background rendering in this picture really makes me happy, and the vignetting is a feature, not a bug, in this instance.

Nikon Z8 | Viltrox 55mm F1.8 Evo | F1.8 | 1/3200 sec | ISO 64

There are a few things to complain about with its performance. There's heavy vignetting at F1.8, which doesn't completely go away until around F4 (though it's much improved by F2.8). I also found myself wishing it could focus a bit closer than 0.43m (16.9"), though that distance isn't unusually far for 50mm F1.8 lenses.

Overall, I found myself really enjoying shooting with it, and loving the photos it produced. Sure, I could certainly find reasons to covet Viltrox's higher-end "Pro" 50mm F1.4 – it has a switch to declick the aperture, more robust weather sealing and linear focusing motors – but I don't think I'd actually need anything more. And that's a nice feeling to have about a lens that costs $370.

Has the digital film project just fixed one of its most annoying problems?

Digital Photography Review news -

Image: I'm Back

Crowd-funded startup I'm Back has developed a clever fix for one of the drawbacks that photographers have pointed out in their digital module for film cameras.

The I'm Back Roll, which is currently approaching $1M of backing on Kickstarter, is a self-contained APS-C sensor module designed to fit into the film bay of legacy 35mm film cameras.

One of the challenges this latest project hadn't overcome was the need to activate the sensor before the camera body's mechanical shutter could then define the exposure.

When the Kickstarter opened, the company showed renderings of a Bluetooth-connected trigger unit that you would have to attach to the camera body, initiating a digital exposure so that the sensor would be active when the mechanical shutter opened.

This (along with the sensor size smaller than the cameras were originally designed for), was one of the main areas of concern expressed by backers.

The company has designed a clever workaround: a shutter button that screws into the camera's shutter button.

In response, the company has designed a clever workaround: a shutter button that screws into the camera's shutter button.

The "Sync button" add-on is a small additional button that can screw into the cable release threads of cameras that have one. The company also suggests another version may be possible without the thread, presumably to be glued onto cameras without a threaded shutter button.

The renders of the button show a flat cable extending from the button but don't show what that cable would need to connect to. The company's development video suggests it will need to connect to the I'm Back Roll unit, to avoid the latency that a Bluetooth trigger is likely to have.

While we've repeatedly stressed the many challenges that stand in the way of creating a quasi-universal digital module for old film cameras - challenges that prevented the original Digital Film project, back when the aim was to perpetuate the use of film bodies as an alternative to switching to dedicated digital cameras - we've been impressed by I'm Back's persistence to make it possible to revive old film cameras for the fun of it. And, even if the implementation still looks like it may be a bit clunky, it's an undoubtedly clever idea.

The Sync button can be added as an option during checkout and existing backers can add one to their order for around $38 (it costs 20 Swiss Franks, with an additional 10 CHF for postage to the US).

Fujifilm's controversial camera has quietly become what everyone wanted

Digital Photography Review news -

When the Fujifilm X half, a compact camera designed to provide a whimsical, nostalgic shooting experience rather than technical prowess, launched, it cost an eye-watering $849 in the US. Many commenters balked at that price, saying that they might have considered it as a fun toy, were it closer to $500.

Well, that time has come. The X half is currently on sale at multiple US retailers and on Fujifilm's own site, selling for $550, a substantial markdown compared to its launch price. But is that a sign that Fujifilm is so desperate to sell the cameras that it's willing to mark them down by around 35%?

Buy at Amazon.comBuy at AdoramaBuy at B&H Photo

Not quite. For the past few months, US stores have been selling the X half for $649, which is much closer to its price in countries like the UK or Japan. While some marked that as a sale price, others, like B&H and Fujifilm's official store, show it as a permanent reduction. And indeed, the camera hasn't sold for above that on Amazon since December 2025, according to price tracking site CamelCamelCamel.

Again, though, this isn't necessarily a sign of the camera's failure. When the X half launched in the summer of 2025, the environment around the US market was murky, as the country's arbitrary import tariffs sparked trade wars with several countries, including China, where the X half is made. While few companies ever actually confirmed their strategy, we wouldn't be surprised if many products launched during that time had some extra padding in their prices to avoid the companies having to later raise prices on newly-introduced models.

If the X half's price kept you from picking one up, your time may have come

Fast forward to the present day, and things have somewhat settled down, with the US Supreme Court ruling that those tariffs were introduced illegally. While that may not mean that the battle over tariffs is over, it does at least seem like Fujifilm is comfortable selling the X half for $200 less than when it was introduced, and even letting it go on sale to bring the price down further.

Of course, there were things people disliked about the X half beyond just the price, and those aspects haven't changed. The company has released a few software updates since we reviewed the camera, but none of them have fundamentally changed what the camera is. But if the X half's price was the main thing keeping you from picking one up, your time may have come.
