TC|Daily | Netstar CTO Cliff de Wit on IoT, AI and astrophotography

Cliff de Wit

Cliff de Wit, a former Microsoft South Africa director and now chief technology at Altron’s Netstar, is passionate about many things: skills development, the internet of things, artificial intelligence … and even astrophotography.

He joins TechCentral’s Duncan McLeod in the TC|Daily studio for a wide-ranging — and fascinating — discussion on some of the latest technologies Netstar is exploring that take the company’s offerings well beyond the traditional tracking and recovery of vehicles it’s traditionally known for.

Well known in developer circles — he maintains a keen interest in software development as well as in education and skills development from his Microsoft days — De Wit chats about how Netstar is taking the vast amount of information the company collects daily, and refining it into something forward-looking, useful and actionable.

He also takes us into the world of astrophotography, and much more besides.

A new generation of black artists are changing fashion photography

As a teenager growing up in Peckham, an ethnically diverse area of London, the photographer Nadine Ijewere observed the way that the women around her dressed. The neighbourhood “aunties”, as all older women were known, paired Nigerian patterns with Gucci handbags and Burberry motifs; they would style their afro hair in a way that was almost sculptural. Ijewere was interested in fashion photography, but she began to notice that the prints and hairstyles she saw everyday didn’t appear in magazines. She didn’t understand why these “pieces of art in themselves” were not more visible. At weekends, she would take photographs of her friends, many of whom were of mixed heritage like her, in the local park.

In 2018, at the age of 26, Ijewere became the first black woman to shoot a Vogue magazine cover, featuring the singer Dua Lipa draped in white feathers. Ijewere soon became known for her ethereal backdrops, her work with mixed-race models and her meticulous attention to black hair. In 2020, she did another photoshoot with Vogue, which accompanied a piece praising Nigerian “aunties”. The women in the shoot wore traditional head wraps and metallic floral and chequered prints in clashing colours. “I looked at those photographs and saw the women I grew up with,” Ijewere said. “I saw my heritage. And it was special.”

Almost 50 years before Ijewere’s “auntie” shoot, another black photographer, Armet Francis, took a photograph in Brixton, a neighbourhood not far from Peckham. In the picture, a stylish young black woman wearing a lilac suit leans back on a wooden chair in the middle of a road, an umbrella in hand. She looks aloof and carries herself with confidence, seemingly oblivious to the dreary weather and the workaday setting. Francis had been commissioned by a fashion magazine, but wanted to be subversive: instead of shooting in a studio, he went to Brixton Market, in an attempt to record the “proper reality of everyday black life”.

Since the mid-19th century, black photographers have sought to capture images that reflect the lives, preoccupations and personalities of black subjects. In the process, they have worked to rectify centuries of hackneyed representations. Francis was one of a small group of photographers to do this in Britain. In the 1960s, he moved away from the fashion industry towards a lifelong project: documenting the experiences of the African diaspora in the Americas and Britain. He had been struck by the fact that one rarely saw black people featured in magazines, beyond reports about famines in Africa. He wanted to photograph the black diaspora in all its vibrancy: “to me, they are home pictures,” he said.

In 20th-century Britain, black photographers were seldom published widely, and discrimination against them was common. James Barnor, one of Francis’s contemporaries, only attained mainstream recognition as an octogenarian. Now his work stands as a vital historical document of black societies as they changed. In the 1950s, Barnor witnessed Ghana’s independence movement; during the swinging Sixties, he photographed members of the African diaspora in London.

Both Barnor and Francis explored black identities as they fractured, shifted and evolved across continents. Many of today’s black photographers draw on their work, consciously and subconsciously – especially those working in the fashion industry. According to Antwaun Sargent, the curator of an exhibition at the Saatchi Gallery about a new generation of black fashion photographers, these young artists are attempting, like Barnor and Francis, to “make beauty from their real, if once unseen, reflections”. Sargent believes that “these image-makers are in the best position now, over any generation that came before them, to make a lasting impact.”

Before British-Ghanaian photographer Campbell Addy first encountered Barnor’s work in 2018, he had only seen photographs that looked at Africa through a white lens, focusing on poverty, slavery and war. Barnor’s photos were different. They showed contemporaries of Addy’s grandmother in Ghana and of Ghanaians moving to London. Addy hadn’t seen anything like them before: “It was classy, it was fashionable. It was beautiful. It was modern.” Barnor made Addy feel seen “in a way that only those who have been detached from their culture can understand”.

As a child, Addy moved from Ghana to south London. For a while after his arrival, his new friends would make fun of his accent. Eventually, the accent disappeared, but the feeling of difference remained. He was also frustrated when he visited Ghana: he didn’t know Twi, the main language spoken in Accra, well enough and couldn’t quite grasp the cultural nuances.

Addy’s dual identity has helped him draw on different cultural traditions in his work. “Ignatius”, an early photographic series, pays homage to Ignatius Sancho, the first known black Briton to vote. But elements of the styling and set design nod ironically to the British royal family.

In 2019, aged 26, Addy shot Naomi Campbell, one of the world’s most-photographed black women, for the Guardian. Later, reflecting on the shoot, Campbell noted that it was the first time she had been photographed for a mainstream publication by a black photographer in her 33-year career. To her, “there was something in that moment that felt sacred.”

Feeling seen Campbell Addy has been commissioned by many of the world’s leading publications (top). Addy’s work tells stories about self-assured black lives (middle). He draws upon both the British and Ghanaian aspects of his own identity (bottom)

Addy and Ijewere are just two members of a new generation of black photographers opening up opportunities for black artists working in fashion. Ijewere is establishing her own studio in south London, where she hopes to give younger photographers the space and equipment they need to start out. Addy knows that there is much work to be done. “Black photographers are doing well right now,” he said. “But I sometimes fear we will get smudged out of history. And I don’t want to be a trend.” The best way to make sure this doesn’t happen? “We need to keep on being visible,” he said. “People will look at our work and know that we exist.”

The exhibition “The New Black Vanguard” runs from October 28th to January 22nd 2023 at the Saatchi Gallery in London. It features the work of 15 young black fashion photographers, including Nadine Ijewere and Campbell Addy

Step out of your comfort zone for better images

October 9, 2022

In his latest column for AP, nature photographer Marsel van Oosten reveals how facing his fears and leaving his comfort zone led to success

I often hear that I have a very recognisable style. When asked what it is, people often use words like ‘simple’, ‘clean’, ‘graphic’, ‘uncluttered’, and even ‘sterile’. I agree with all those words because they perfectly describe the artistic form that I am trying to create in my work.

As a photographer, you not only need to decide what you want to photograph but also how you want to photograph it. Every photographer has his own preferred way of shooting – one that gives the best and most pleasing results. For me, that means simple, clean, graphic and uncluttered images. As a result, I always find myself drawn to subjects with a strong, graphic shape, in a habitat with as little distractions and visual clutter as possible. For that reason, I prefer photographing deserts over grasslands, and dead trees over live ones. I didn’t always know this.

If you have a particular style, it’s usually the result of certain preferences you have as an artist. Then, once you’re very comfortable with that style, you become extremely efficient and almost go into autopilot. Everything is easy because you’re in an environment that fits your photographic style, so you immediately know what to do. You work fast and efficiently and become very productive. Whereas if you’re suddenly in an environment that you are not very familiar with, or even dislike, that’s a whole different ball game.

Abandoning the comfort zone

Many years ago, my wife Daniella and I went on a trip to Costa Rica. We both love the wilderness and a rainforest is as wild as it gets. I had just started in photography and was excited to photograph the wildlife. But, as much as I enjoyed the experience, I wasn’t inspired to take any photographs. I checked my Lightroom catalogue to see how many images I shot on that trip: ten. It was a pivotal moment in my development as a photographer as it forced me to figure out why I was not inspired. Conclusion: too much visual clutter.

Self-portrait in Shaanxi, China, at the exact location where Marsel van Oosten shot the award-winning ‘The Golden Couple’ image

For the next ten years I stayed far away from forests. The ‘cleaner’ the landscape, the more inspired and happier I was. But, after a while, my decision started bothering me. Every now and then I saw beautiful images taken by other photographers in dense forests and realised that I was running away from a challenge. Years later, I saw a very bad photograph of golden snub-nosed monkeys, in a brochure, somewhere in China.

They were the most fascinating looking monkeys I’d ever seen, and when I learned that they were endangered I knew I had to photograph them. Lichens are the main staple of the monkeys’ diet, and dead trees have the greatest lichen coverage. Unfortunately, those are being taken by the timber industry. The monkeys are also eaten by the local population. Anyhow, the problem was: they live in dense forests.

I absolutely love forests from a nature-loving perspective, but a forest is nothing but clutter. For the first time in my career, I had to think long and hard about how to face my fears, and how I could overcome my ‘clutter-phobia’. No more relying on intuition… it was time to get way out of my comfort zone.

In an effort to get control over the immense clutter in the backgrounds, I decided to use a polariser to limit the amount of reflections off the leaves, and to use flash to create separation between the subjects and the forest behind them. Flash enabled me to control the ambient lighting and get sufficient light on the monkeys while, at the same time, being able to underexpose the backgrounds using polarisers, decreasing the amount of reflections.

This proved to be the recipe for my project, and many of the images I shot there are among my favourites. One of them even won me the grand title Wildlife Photographer of the Year. Had I decided to stick to my standard routines, and comfortably continue on autopilot, this would never have happened. If it doesn’t challenge you, it doesn’t change you.

The Art of Place in Space

Bruce Presents Astrophotography – Virtual Zoom Webinar 

The night sky has long held us captive with its beauty and wonders, only to disappear with the coming of the sun. But photography, beginning with the first pictures of the Moon in the 1800s, has enabled us to see into the dark reaches of space, capturing a moment that can be shared anytime. Advances in photographic technologies have given way to Astrophotography, the imaging of astronomical objects, celestial events, or areas of the night sky. Modern Astrophotography is not only dazzling to behold, but also provides important data and research support on objects invisible to the human eye such as dim stars, nebulae, or galaxies.

Cancer survivor continues passion for photography and enjoying life

PARKERSBURG, W.Va. (WTAP) – Lorain Fought – or “Rain” as she prefers to be called – is a four-time breast cancer survivor, two of those times with breast cancer and she is currently battling lung cancer.

Despite the many different bouts with this disease, Rain doesn’t let any of this stop her from continuing to enjoy her life.

As she continues to take up many of her passions, including one that has garnered her both local and national attention.

“I just don’t want to sit around the house,” says Fought. “I want to do something. I got to keep busy. I want to enjoy everything that’s on this Earth, one way or the other.”

After multiple fights with cancer, Fought is not letting this disease wear her down.

She continues many of her passions. One of them being photography.

Something she got back into when she got on Facebook and her friends told her how good she is at it.

Fought says, “And I’m like, ‘You know, maybe a calendar. Maybe make a calendar.’”

And since then, Rain has been churning out a calendar almost every year.

Rain says she provides roughly 150 calendars each year and they go out fast, as people love her wildlife photos.

“I love wildlife. I love nature. I love everything, I think,” says Fought. “So, I’ll go out in the woods and like – for this calendar here – some of the pictures, I sat for probably 10 hours.”

Rain’s photos are not just for calendar use though.

As her work has been featured on many publications and media. Both locally and nationally.

“And I’ve been published in ‘Birds and Bloom,’ ‘Wild and Wonderful West Virginia,’ the bird digest out in Marietta. Also, the Chicago Tribune, the Columbus News,” says Fought.

Rain says that the calendars are also more than a hobby, as she uses these for herself to track her treatments.

“If you look through mine, which you did, you’d see CAT scans, doctor appointments, blood work. You’d see all of those appointments in there,” says Fought. “And I know people do it on their phones, but I’m old school. I use a calendar.”

Fought says that the photos found in these calendars will also be used in “thank you,” “get well,” and other greeting cards at Memorial Health Systems.

2. Aspen Tree or Birch?

Where do we come from? What is the meaning of life? Is it an aspen tree or a birch? These are the questions that have plagued mankind since the dawn of time. Without a doubt, both are beautiful trees, loved by nature photographers, hikers and all seekers of fall color around the country. But what is the difference? Is it the way they taste? The sound that each makes when they fall in the forest and no one is there to hear their cries? Let’s dig a little and see if we can find out.

The whites and ingidos of an alpine meadow of lupine mirror the crags and glaciers of Mount Rainier National Park’s eponymous peak. The highest summit in the Pacific Northwest, the dormant volcano slumbers peacefully beneath the quiet grandeur of a midsummer sunset. Fine Art Limited Edition of 100.

3. What Are Peter Lik Style Prints?

In reality, there is simply no such thing as Peter Lik Style Prints. There are acrylic face-mounted photography prints, produced by thousands of photographers around the world and there are acrylic face-mounted photography prints produced by artist Peter Lik. These truths are separate from each other, as one style does not belong to the other.

4. Ansel Adams | Black and White Photography

Ansel Easton Adams (February 20, 1902 – April 22, 1984) was a landscape photographer and environmentalist known for his black-and-white images of the American West. He helped found Group f/64, an association of photographers advocating “pure” photography which favored sharp focus and the use of the full tonal range of a photograph.

5. Imitation Is Not The Sincerest Form of Flattery

Flattery, is often used in a dishonest way, as a means to achieve what someone wants for themselves. An employee, hoping for a promotion, may compliment the bosses new suit. A waitress, may use flattery to increase the chances of being tipped. Even laughter, when used correctly can flatter and therefore influence a person’s opinion of you.

6. My Scandalous Affair With The Sony A7RIV

As described in my previously released, highly debated and riot inciting story about the FUJI GFX100 and Sony A7RIV, I explained my history with the Canon EOS system and a little bit about myself as a landscape photographer. I have been a Canon shooter since I began my adventure with photography, beginning with a Canon 40D, then a 50D, a 5D2, a 5D3 and finally a 5DSR.

9. The Great American Landscape Painters

Many landscape photographers today, including myself, have found beauty and inspiration in the works of these masters. The composition, light and overall mood created in many of these paintings hold the same allure to landscape photographers of today. Please read on to learn more about the Hudson River School, the movement itself and more about three of the painters who helped cement these works into history.

10. The Best Fine Art Print Mediums Explained

These days, you can have your photographs printed onto almost anything. Care to see your photos printed on a natural plank of wood freshly cut from a tree? No problem. A slab of cold steel? You betcha. How about a t-shirt, coffee cup or a backpack? Consider it done my friend.

The Rainbow Mountain at Paria Utah under the Milky Way – David Lane Astrophotography

Once you click on the image it may take 15 seconds or more to render!

What some have come to call the Rainbow Mountain is at Old Paria, or Pahreah, which is a ghost town on the Paria River in Grand Staircase-Escalante National Monument in central Kane County, Utah, United States. It was inhabited from 1870 to 1929, and later used as a filming location. it’s on Highway 89 between Kanab, Utah and Page, Arizona. Although a regular vehicle can make this drive rather easily do not attempt it if rain is in the forecast or if it has rained recently. The road turns into an impassible slime pit for hours.

Paria is one of the oddest places on earth. If you like geology, you are going to LOVE Paria! There are more colored layers of rock here than you can shake a stick at. Here you can see the layers of the area that were laid down in beautiful colors over millions of years. Many other places you can see bits and pieces of the rock layers, here they are all exposed in one spot to gape at.

The Outlaw Josey Wales was filmed with Clint Eastwood here in the 1970s. There was a cool old town till some dimwits burned it down about 10 years ago,

HII rich region in Norma

This very interesting region in Norma contains many HII features as well as many other interesting objects. Below you can see an annotated version with the most clearly visible objects identified, except for the HII region in the bottom left corner. I couldn’t find out what this is called, so if anyone knows please let me know in the comments below
Somehow these objects and this fov get rarely imaged, which made it all the more interesting for me to try and get a nice image out of this.

Most eye catching are the RCW objects, which are different types of objects. Let’s have a more detailed look at each of them.

RCW 103 Supernova Remnant

RCW 103 is the brightest region of hydrogen gass in this image. It is a supernova remnant of a star that went supernova around 2000 years ago at a distance of 9000 light years from earth.
It (probably) has a very interesting neutron star in the center: This might very well be the slowest rotating pulsar we currently know of.
“The source exhibits properties of a highly magnetized neutron star, or magnetar, yet its deduced spin period is thousands of times longer than any pulsar ever observed.”

RCW 104 and Wolf-Rayet 75

Wolf-Rayet stars are extremely hot stars. Their surface temperatures range from 30,000 K to around 200,000 K, hotter than almost all other stars. They have broad spectra, but lack in hydrogen. They cause strong stellar winds, thus shaping their environment and feeding it with material.
In this case we can see such a star (WR 75) in the middle of the HII region known as RCW 104 which is shaping and ionizing the surrounding hydrogen gass.

RCW 106

RCW 106 is a cloud of hydrogen gass and dust. In fact, it contains so much dust that much of hydrogen gass and a lot of stars are hidden from sight in the visible light. RCW 106 contains some very massive O-type stars. These stars (probably) form in the most dense areas of the gass and dust cloud and they live only briefly. They burn through their fuel in tens of millions of years.

RCW 102

RCW102 is another interesting gass cloud that’s a mixture of ionised hydrogen gass and dust. Neighbouring RCW 102 we can find the bright planetary nebula RCW101, Menzel 3 or the ‘Ant Nebula’.

RCW 101, also known as Menzel 3 and the Ant Nebula

Menzel 3 is a young bipolar planetary nebula that is composed of a bright core and four distinct high-velocity outflows. It is expanding at a rate of 50km/s and located at around 8000 lightyears from earth.

Open star clusters

There are numerous Open Clusters like NGC6115, Ruprecht 116, Ruprecht 176, Pismis22 and many more.

Planetary nebulae

Apart from the Ant nebula there are two more planetary nebulae that can be seen in this image. They are Pe1-4 and WRAY 17-74.
