You’re scrolling through a feed, minding your own business, and then you see it. A grainy, sepia-toned shot of a muddy intersection from 1924 positioned right next to a high-definition 2026 capture of the same corner, now overflowing with glass skyscrapers and electric charging stations. You stop. You always stop. There is something fundamentally weird and hypnotic about then and now images that bypasses the logical part of our brain and goes straight for the "time travel" button. It isn't just about seeing how things changed. Honestly, it’s about the shock of realizing that the world we walk through is basically just a ghost story layered on top of reality.
We’re obsessed with this stuff. Whether it’s a celebrity’s face maturing over thirty years or a forest that turned into a shopping mall, these side-by-side comparisons offer a perspective we can't get in real-time. Life moves too slow for us to notice the decay or the growth. Then and now images just rip the band-aid off.
The Psychology of Visual Time Travel
Why do these photos work? Why do they go viral on Reddit’s r/OldPhotosInRealLife or dominate Instagram Discovery? Psychologists often point to something called "reminiscence bumps" or "temporal comparison theory." Basically, our brains are hardwired to look for patterns and discrepancies. When you see a 19th-century factory next to a modern loft apartment, your brain works overtime to reconcile the two. You start looking for the "anchor"—that one window frame or brick pattern that survived a century of demolition. Finding it feels like winning a mini-game.
It’s also about mortality. Scary, but true. Looking at a "then" photo reminds us that a version of the world existed before we arrived, and the "now" photo proves that the world is currently leaving us behind. It’s a bit of a reality check.
When Then and Now Images Go Beyond Nostalgia
In 2024, the "rephotography" movement took a massive leap forward. It’s not just hobbyists anymore. Urban planners and climate scientists are using these visual anchors to prove points that spreadsheets just can't communicate. Take the work of Christian Åslund, a Swedish photographer. He worked with Greenpeace to recreate photos of Arctic glaciers from the early 20th century. When you see a massive wall of ice in 1920 replaced by a puddle of gray water in 2020, you don't need to read a 50-page climate report. You get it instantly.
Architecture is the biggest playground for this. In cities like Warsaw or Berlin, the then and now images are often heartbreaking because of the total destruction during World War II. You see a grand, ornate opera house, and then you see a brutalist concrete block. The contrast tells a story of loss that a history book struggles to convey. It’s raw. It’s right there in front of you.
On a lighter note, look at the "glow up" culture in the celeb world. We love seeing a kid with braces and a bowl cut turn into a Hollywood A-lister. It makes greatness feel achievable. It suggests that our current state isn't our final state.
The Tech Making This Easier (and Weirder)
It used to be hard. You had to find the exact focal length, the exact time of day for the shadows, and the exact spot where the original photographer stood. One inch to the left and the alignment was ruined. Now? We have apps like Rephoto and AI-assisted overlays that help photographers line up their shots with transparent "ghost" images of the past on their phone screens.

But there’s a dark side to the modern version of these images. We’re entering an era where the "then" might be real, but the "now" is filtered beyond recognition, or vice versa. Digital restoration is great, but sometimes it cleans up history too much. When we "colorize" a photo from 1860, we are making an educated guess. If we get the colors wrong, we’re essentially lying about the past to make it look "cool" for a TikTok transition.
Real Examples of Transformation That Break the Brain
Think about New York City’s Times Square. In the 1970s, it was—let’s be real—a total dive. It was gritty, dangerous, and filled with neon signs for things your grandmother wouldn't approve of. Today, it’s a sanitized, LED-soaked canyon of corporate logos. When you put those two images together, you aren't just looking at different buildings; you’re looking at two completely different philosophies of what a city should be.
- The Ghost of the High Line: Before it was a trendy park where tourists buy $8 popsicles, the High Line was an abandoned, weed-choked railway. The photos of it from the 1990s look like something out of The Last of Us.
- The Dubai Explosion: Look at a photo of Dubai from 1990. It’s basically a road and a couple of buildings in the sand. Look at it in 2026. It’s a sci-fi skyline. That kind of change usually takes centuries, but here it happened in a single generation.
- The Chernobyl Nature Takeover: This is the haunting side of the trend. Images of Pripyat in 1986 vs. today show how quickly nature "reclaims" its territory once humans leave. Trees growing through gym floors. It’s fascinating and terrifying.
How to Create Your Own "Then and Now" Project
If you want to do this right, don't just snap a photo of a building. You need to be a bit of a detective.
First, hit the local archives. Most city libraries have digitized their photo collections. Look for "fixed points"—statues, ornate stonework, or street layouts that haven't changed. Trees are actually bad anchors because they grow or die. Stones are better.
Second, pay attention to the lens. If the original photo was shot on a wide-angle lens and you use a telephoto zoom, the perspective will be warped. The buildings won't "line up" in the frame. You want to match the "compression" of the original shot.
Third, wait for the light. If the 1920s photo has long shadows stretching to the left, try to shoot in the late afternoon. It makes the transition in a slider or a video much smoother.
The Misconception of "Progress"
We often look at these images and assume that "now" is better. But is it? A lot of people find that looking at then and now images actually triggers a sense of "solastalgia"—a term coined by philosopher Glenn Albrecht. It’s the distress caused by environmental change in your home environment. You see the local park replaced by a highway, and even if the highway is "progress," it feels like a wound.

The most powerful images are the ones that show what we've lost. Beautiful Victorian architecture replaced by a parking lot. A vibrant community replaced by a gentrified "luxury" zone that has no soul. These images serve as a warning. They remind us that the decisions we make today about our environment are the "then" photos of tomorrow.
Actionable Ways to Use These Images Today
- For Business Owners: If your company has been around for decades, put a photo of the original shopfront in your window. It builds instant trust. It says, "We survived."
- For Social Media Growth: If you're a creator, use the "green screen" effect to stand "inside" an old photo of your hometown. People love the "then vs now" storytelling because it feels personal and authentic.
- For Personal History: Recreate a photo of your parents or grandparents in the same location they stood. It’s the best gift you can give a family member. It connects the generations in a way a standard portrait never can.
The world keeps spinning, and we’re all just passing through. These photos are the only way we have to actually see the footprints we leave behind. They remind us that everything is temporary—and that’s exactly why we can’t stop looking at them.
To start your own project, visit your local historical society's digital portal and find one landmark within five miles of your house. Take your phone, stand where the original photographer stood, and try to find that one "anchor" point that hasn't moved in a hundred years. It changes how you see your neighborhood forever.
