Stock, 3D, photos, or AI? Four ways to create mockups

A mockup is a representation of a digital product in a real-life situation, with the goal of enticing potential buyers to purchase. Or, to put it more customer-friendly, to show customers how a work of art fits into their lives. I have created hundreds of mockups over the past few years, some quite realistic, others completely absurd. In this blog post, I show a selection of those mockups, created in four different ways. Print on demand I have had a webshop at the print-on-demand platform Art Heroes since 2014. Over the years, I have added about twelve hundred photos, artist… Read More

The Three Star Winter of ’26

In the past, I’ve often reviewed winters on this blog. With a focus on the photographic aspects of those winters, the fresh blankets of snow that give the city a completely different look. But in recent years, there hasn’t been much to review. Holiday The last snowfall of any significance was in February 2021. It created a nice thick blanket of snow, which lasted well over a week. And it was even possible to skate on natural ice. That winter period felt like a kind of holiday in the otherwise gloomy covid period. Unsettled But after that, winters were mostly… Read More

10 Fake Album Covers By Bands That Unfortunately Don’t Exist

I often hear or read something—a word, a few words, or a sentence—that makes me think: this would make a great name for a band, or a good song title. Until recently, those ideas usually faded into oblivion. But since AI exists, it’s relatively easy to quickly conjure up a fake album cover for such an idea. I actually thought it was a rare quirk, this fantasizing about fictional bands and albums. But a simple search on Google reveals that entire communities exist around the topic of fake album covers. Well, then I can certainly write a blog post about… Read More

December Evenings in Rotterdam

The blue hours are the two magical moments of the day, just before sunrise and just after sunset. The light is ideal for taking dramatic city photos. These blue hours are there all year round, but in the middle of summer, they’re at rather inconvenient times. In December, on the other hand… New Year’s Dive I’ve often written about January mornings on this blog. It’s the time of year when the sun rises around 8:30 a.m., meaning the blue hour, that favorite part of the day for photographers, roughly coincides with the morning rush hour. So you don’t have to… Read More

Countdown: the Best Photos of 2025

The frequency of my blog posts has decreased somewhat this year, but of course, I can’t ignore the end-of-year tradition, so here they are again: my ten favorite photos of 2025. Selected from over 5,000 photos taken during walks with fellow travelers A., A., A., I., C., N., and many others. The resulting longlist still contains 236 photos, which in themselves form a cinematic overview of the year. But I don’t want to bore my readers with a top 236. So, after a painful selection process, the top 10 below remained. 10 – Motorway Composition This year, the new section… Read More

False accusations of artificial intelligence

Artificial intelligence is becoming more and more of a nuisance for photographers and artists. Usually because your work gets lost among the millions of mediocre AI images that flood the internet every day. And sometimes for a completely different reason: because people (or AI systems?) simply don’t want to believe that your photos are real… Stock photos For about ten years now, I have been uploading photos from my extensive archive to stock photo sites. It won’t make me rich, because the return per photo is disappointingly low. But if those images rot away on my hard drive, I earn… Read More

The Marker Wadden Expedition

Marker Wadden have been there for a few years now, but until recently I didn’t have the chance to visit this newest part of the Netherlands. On a beautiful day in late March, I finally took the ferry from Lelystad with my travel companion R., to take a look at the nature archipelago in the Markermeer. Our high expectations were more than met by both the landscape and the architecture. And the photogenic weather with beautiful cloudy skies also generously cooperated. Zoom out for context, zoom in for details… Markermeer Markermeer is a lake that has only existed since the… Read More

Photobook: a Year in Rotterdam

My own photo book, in large stacks at bookstore Donner, featuring a selection of the thousands of photos I’ve taken of Rotterdam over the last few years—well, that’s a dream of mine. But a hard dream to realize, because the necessary investments are considerable, and the chances of recouping that money are slim. Okay, so let’s start with a very limited edition. Offer A few weeks ago, I saw an advertisement on Facebook from Saal Digital GmbH. As those last four letters suggest, it’s a Gesellschaft mit beschränkter Haftung, a German company which apparently wants to enter the Dutch market.… Read More

Mapping the World’s Time Zones

A world map showing only the time zones; just the borders between those zones, without any context. It creates a somewhat confusing image: straight lines that occasionally form right angles and suddenly turn into messy winding lines. But then suddenly you spot it: coastlines and national borders, Iceland, India, Argentina. With some colors added, such a map seemed like a nice addition to my collection of world maps. But before that map was finished, I discovered some fascinating facts about international timekeeping. Full and half hours How many time zones are there on our planet? Twenty-four, you might think, one… Read More

Countdown: the best photos of 2024

It is a tradition that goes back to the early years of this blog: the annual top 10 of my best photos. Although, “best” is such a value judgment, let’s call it my favorite photos. Or maybe just the photos that have a good story to tell. Since 2016, I have been looking at the photos I took that year every year in mid-December, selecting about 200 for the longlist. What follows is a long and painful process to distill my top 10 from that. Anyway, as long as I have the list and the accompanying blog post ready somewhere… Read More

Bronze and Stone Animals in Rotterdam

The animal kingdom has always been a source of inspiration for art. Anyone who looks around in a city like Rotterdam will see countless animals immortalized in statues, reliefs, and murals. World Animal Day, October 4th, is a good time to take a little tour of these beastly artworks. A photo blog with the theme: Rotterdam’s animals made of bronze and stone. And paint and other materials, but that would make the titlea bit long. Delft Lion Perhaps lions are the most frequently portrayed animals in art, so you can regularly encounter them in Rotterdam. And that’s remarkable when you… Read More
