Street³ Fotografie, Wahrnehmung & echtes Berlin
English is below
In kurz & authentisch & unseriöser Künstler:)
inneres und dann äußeres Fotoauge trainieren und Spaß dran haben.
Wahrnehmung, Fotografie, Streetfood, Walk & beste U-Bahn :)
Dazwischen Berlin in urban, lebendig, divers, dreckig, wunderschön, direkt im Kiezleben, mind. 1 Späti-Getränk, viele Reize und immer wieder ein Fokus. Dein Fokus.
Wirst ihn immer wieder neu, anders, vertiefend für dich kennen lernen.
Zwischen Ostkreuz bis Markthalle 9 wird unser Spielplatz sein.
Ich freu mich darauf :)
ausführlich, seriös:
Dieser Street Walk verbindet urbane Erfahrung, Wahrnehmung und Fotografie in Berlin.
Wir bewegen uns bewusst abseits klassischer Touristenrouten durch Friedrichshain, Kreuzberg und die Übergänge dazwischen. Straßenleben, Menschen, Bewegung und Streetfood gehören dabei genauso dazu wie das Fotografieren selbst.
Dieses Format versteht sich weniger als klassische Fototour und mehr als urbane Erfahrung zwischen Wahrnehmung, Stadtgefühl und Fotografie. Die Kamera dient dabei nicht nur zum Festhalten von Motiven, sondern als Werkzeug, um bewusster zu sehen und Momente anders wahrzunehmen.
Wer Lust hat auf schnelle Touristenbilder oder reine Technikvermittlung, wird hier wahrscheinlich nicht ganz glücklich. Wer dagegen neugierig darauf ist, wie stark Wahrnehmung, Aufmerksamkeit und Atmosphäre beeinflussen, welche Bilder entstehen und welche Erinnerungen bleiben, dürfte hier genau richtig sein.
Das Format richtet sich an fotointeressierte Menschen, an Menschen ausm Kiez genauso wie auch Touris, die Berlin mal anders erleben wollen. Nicht als klassische Tour, sondern näher dran. Manche kommen fürs Fotoauge, manche für die Atmosphäre, manche einfach, um die Stadt (wieder) bewusster wahrzunehmen.
Ich komme aus der Wahrnehmungspsychologie mit meiner Leidenschaft für Fotografie und verbinde diesen Blick mit urbanem Erleben. Und klar, auch der Gang zum Späti darf dabei nicht fehlen.
Die ersten Walks sind Teil einer Beta Phase, in der ich gemeinsame Street Experiences auch ausserhalb von Teamevents ausprobieren möchte.
Damit dieses Format in dieser Form möglich bleibt und sich entwickeln kann, liegt die Spendenempfehlung ab 20€.
Bring Neugier, Kamera und/oder Smartphone für deine Wahrnehmung mit. Der Rest passiert unterwegs.
Ich freue mich auf euch und auf die ersten gemeinsamen Walks diesen Sommer.
This street walk combines urban exploration, perception and photography in Berlin.
We make a conscious effort to stay away from the usual tourist routes, exploring Friedrichshain, Kreuzberg and the areas in between. Street life, people, movement and street food are just as much a part of the experience as the photography itself.
This format is less of a traditional photography tour and more of an urban experience that blends perception, a sense of the city and photography. The camera serves not only to capture subjects, but as a tool to see more consciously and perceive moments differently.
Those looking for quick tourist snaps or purely technical instruction are unlikely to be entirely satisfied here. On the other hand, anyone curious about how strongly perception, attention and atmosphere influence which images are created and which memories remain is likely to be in exactly the right place here.
The format is aimed at people interested in photography, at Berliners from the neighbourhood as well as those who want to experience Berlin in a different way. Not as a traditional tour, but something more intimate. Some come for the photographic eye, some for the atmosphere, and some simply to perceive the city more consciously again.
I come from a background in perceptual psychology with a passion for photography, and I combine this perspective with urban experiences. The first walks are part of a beta phase, during which I’d like to try out shared street experiences outside of team events as well.
To ensure this format can continue in its current form, the suggested donation is from €20.
Bring along your curiosity, a camera or a smartphone to capture your experiences. The rest will happen as we go.
I look forward to seeing you all and to our first walks together this summer.

Real Long Term Friendship
Nice! You are looking for real long time friendship! You might have already lived in Berlin or other big cities and experienced the "Anonymous" culture for a while. Meeting random people over and over and never see the same person again! In order to find "Real Long Term Friendship" in Berlin, do as follows:
* You should not care how many people are joining this meetup.
You RVSP. Even if only one person is joining. Because if everyone are waiting for everyone else to RVSP, nobody joins and nobody finds a new friend.
* You do not care how many people of the opposite sex are joining.
You are looking for friends. Finding the best romantic partner in the world, while avoiding not very attractive others, can be your other goal, for another time. Here we are looking for Friends. Real ones.
* You are going to risk a very precious property of yours: Your time!
Yes, there are thousands of opportunities in Berlin, there might be a rock concert for free, a birthday party you might miss, an important person might call you and invite you spontaneously, but you never find new friends until you decide to risk your time and meet people anyway. "I will check my calendar and get back to you" also does not work. Commit your time and spend it. Trust me, you won't go bankrupt ;-)
* You are ready to use your phone as a real phone!
You might have been using your phone as a tablet to visit Instagram and Facebook and watch movies. But if you want to find friends, you must know that people might take your phone number and give you theirs. That means they will Call you! And you have to pick up the phone and answer it. If you want to find new friends, you must be ready to do something really hard for the first time after years: Call people first, and if they called you: Answer your phone!
* You are going to meet some people twice!
That's the point of friendship. We already can experience random encounters with random people in random places one at a time. But that is not called friendship. If you want friends, you must be ready to meet the same person more than once.
If you agree with above, RVSP and COME! You will meet other people who think the same way.
P.S: Now that you've read all the way down to here, I suggest you [watch this animation](https://player.vimeo.com/video/547249272?h=22f3dd0f6f).

Spaghetti Eis and a stroll through the park
Hello people,
Let’s have a very typical German ice cream together: the spaghetti ice cream. We‘ll go to Berlin‘s oldest ice cream cafe. Of course you can also order something else.
Afterwards, we will go for a little stroll in the park, which is right next to the cafe.
Please update your RSVP in time if you cannot make it - have respect for others who are interested and me who doesn’t want to eat ice cream alone ;-).
See you soon,
Lena
Book Swap in Gleisdreieckpark 📚 – Social Butterfly Club 🦋
Bring a blanket, maybe a drink or snack, and 3–5 books you’d like to pass on, and spend a relaxed Sunday afternoon with fellow readers at the Gleisdreieck Park.
Novels, philosophy books, poetry, comics, forgotten favorites — in any language — everything is welcome. Maybe you’ll leave with fewer books — or more. Both are part of the adventure.
This is not a formal market or networking event — just a cozy little community gathering with books, conversations, and a bit of curiosity. Come browse, swap, chat, or simply enjoy the atmosphere on the grass.

The event is free of charge.
It is advisable to get a drink though. This is a cafe, we need to have at least half of the people on each table with a drink. They accept only cash and most hot drinks cost from 2.50 to 3.50.

Chitta Walks - Awareness in Motion
Chitta Walks is for people whose days move fast, while the mind never fully lands. Thoughts keep looping even when nothing is urgent. The body moves, but attention is elsewhere. Over time, this disconnect drains clarity and ease.
This walk is a simple reset.
We meet in Berlin’s Tiergarten and walk at a gentle pace. Parts of the walk are in silence, with light guidance and a few short prompts. The walk itself is the practice, bringing body and mind back into the same moment.
No apps. No performance. Just a clear space to slow down and notice what is happening.
If you want to slow down without withdrawing from life, join a Chitta Walk.
✨ **What to expect (approx. 90 minutes):**
* A short arrival and orientation
* A guided silent walk (phones off, no conversation)
* One concise science-based impulse on attention or stress
* Optional reflection in pairs or small groups
* A simple takeaway or experiment for daily life
🚶**Who this is for:**
* Professionals, creatives, and people in transition.
* People who feel mentally busy and want more clarity and balance.
* Those curious about mindfulness, but grounded and practical.
* Anyone comfortable with silence and gentle self observation.
🔔 **Practical notes:**
* Duration: 60-90 minutes
* Wear comfortable shoes and weather-appropriate clothing
* No prior experience needed
* Group size is limited to keep the space quiet and focused
🧭 **Facilitator:**
My name is Partha Sarathi, you can call me PS. I have lived in Berlin for over 12 years. With a background in physics and materials science, my interest in mindfulness grew through personal experience with stress and health challenges. I facilitate the space and structure of the walk, inviting shared exploration rather than instruction.
🤔 **Why Chitta Walks?**
Chitta is a Sanskrit word referring to the mind or field of awareness, used here in a practical, non-religious sense.
Chitta Walks is about noticing how the mind works by slowing down and walking together. Mindful walking makes thought patterns visible in real time, while moving and sensing in the world.
The name points to a simple capacity: noticing what is happening in the mind without immediately trying to fix, judge, or optimize it.
🌿 **Possible effects:**
A calmer nervous system.
Clearer attention.
A felt sense of being more present in your body.
Subtle insights into how your mind reacts under everyday conditions.
A quieter, more grounded way of moving through the city.
**Come as you are. Walk. Notice. Leave with a little more space inside.**
