But I think you have to start somewhere, so here goes.

In 2025, after a sudden change in my life, I decided I needed to think about a project. Not just to feel better, but to really live, move forward and create something that reflects who I am.

And I ended up choosing a new destination: Estonia. Those of you who know me know that I’m passionate about the history of the Soviet Union. Don’t worry, I’m not political or a communist. It’s just fascinating to see how it all worked.

I would have liked to go to Russia one day, but… you know what happened in 2022, four years ago already, or too long ago, I don’t know.

So I thought about it for a whole month. We don’t know each other very well yet. After 10 articles, including 2 with photos, you don’t know anything about the trip I took to Norway, a month in a camper van. And it made an impression on me, I wanted to recapture that feeling of the north.

Yes, I know, Estonia is nothing like Norway. But I’m looking for that wild nature, that feeling of being alone in the world, in a place that takes your breath away.

It took me over a month to make up my mind, think things through and compare the options. And I finally settled on Estonia.

The time available for this trip will be limited. I work, so the trip has to be short, organised and well thought out. The goal: three weeks, a real road trip.

Another detail: I will be travelling with a tent for most of the journey, particularly when crossing Germany and Poland. From Lithuania onwards, I will probably book a few Airbnbs, just for a change and to enjoy the Baltic countries in a different way.

Now I had to make a plan. Here it is:

• 1. Motorcycle & Equipment and maintenance
• 2. Camping & Comfort
• 3. Clothing & Protection
• 4. Safety & First Aid
• 5. Documents & Logistics
• 6. Media & Content Creation
• 7. Take the trip, share it on Instagram and follow it on a digital map
• 8. Share it with you afterwards on YouTube, with episodes by country?

This plan isn’t detailed here, as it would be long and not very interesting to read like that. But each point will be explored in the following articles, step by step. Those who want details, get ready!

While we wait for departure, I wish you all a wonderful 2026. And welcome to this first journey with me.

1. Choose the Right Smartphone and Accessories

Most recent smartphones offer excellent photo quality, but here’s what to prioritize:

✔️ A smartphone with a good camera sensor: ideally, a model with portrait mode and good depth-of-field management. Avoid overly obvious AI-generated bokeh effects.
✔️ A tripod (or stable support): to prevent blurry photos.
✔️ A Bluetooth remote or timer: to trigger the shot without touching the phone.
✔️ A ring light (optional): for soft and even lighting, or use the phone’s flash to remove shadows on your face.

Tip: Use tape, a measuring tape, and a marker to mark your positions clearly.

📍 Where to place markers:

📏 To avoid random framing, follow these steps:

• Measure 2.5 to 3 meters from the wall that will serve as the background and mark the spot with tape. This is your position.
• 3 meters behind, mark another point on the floor for the smartphone on a tripod.

2. Prepare Your Environment

A good environment = a successful photo.

✔️ A plain wall as background: white, light gray, or black. Avoid bright colors.
✔️ A room with enough space (5–6 meters if possible for the markers).
✔️ Natural light: stand near a window, facing it or slightly to the side.
✔️ Timer: set to 10 seconds to give yourself time to get in position.

💡 Managing Light

✔️ Natural light > artificial light: avoid bulbs that are too yellow or too white.
✔️ A ring light can help, but place it slightly above your face to avoid shadows under the chin.
✔️ Flash can remove front shadows; uneven lighting on your face is not professional.
✔️ Activate HDR mode to balance contrasts.

3. Smartphone Settings to Optimize

🎯 Recommended photo mode:

• Portrait mode (if available): if the AI works well, it can create a nice background blur (bokeh). Check that the effect is clean; AI can still make mistakes.
• If your phone doesn’t have this mode: use apps like Snapseed or Focos to add blur in post-processing if you want to separate yourself from the background.

📷 Key adjustments:

✔️ Orientation: portrait (vertical).
✔️ Exposure: tap on your face and slide up/down to adjust light.
✔️ ISO: set to automatic to avoid noisy images; smartphones usually handle this better than cameras.
✔️ Focus: enable autofocus on your face (tap the screen to lock focus).

4. Perfect Posture and Expression

The goal is to convey professionalism and approachability.

📌 Ideal posture:

✔️ Straight back, but natural: not too stiff, not too relaxed.
✔️ Shoulders slightly back: to appear open.
✔️ Arms relaxed: avoid crossed arms, which can seem closed off.
✔️ Slight head tilt for a more engaging effect.

🎭 Natural expression:

✔️ Look directly at the camera: creates strong eye contact.
✔️ Smile lightly, without exaggerating: a forced smile can look artificial.
✔️ Relax your jaw before shooting.
✔️ Think of a pleasant moment for an authentic smile.

5. Outfit and Accessories

✔️ Choose attire suitable for your industry.
✔️ Prefer neutral, solid colors (blue, gray, black).
✔️ Avoid busy patterns and flashy accessories.
✔️ Watch the background: avoid a white shirt on a white wall to prevent blending in.

6. Retouching and Framing

📏 Crop the image if needed so your face is centered with some space above your head.

🖌️ Light retouching:

✔️ Adjust brightness and contrast for a more professional look.
✔️ Avoid heavy filters: the goal is to stay natural.
✔️ If the background is not perfect, use an app like Snapseed to soften it.

7. Final Tips

✔️ Take multiple shots to choose the best.
✔️ Test different expressions and postures.
✔️ Check image sharpness before sending.

8. Format and Dimensions

✔️ High resolution: to avoid pixelation on your CV.
✔️ Recommended format: square or slightly elongated portrait.

For those expecting a tutorial with a digital or DSLR camera, I’ve made this tutorial for you.

I also personally keep two versions of Firefox installed, plus Google Chrome. Chrome helps me check that my sites work for most people, because honestly we are still a minority fighting for Firefox’s share of the web. Sometimes I check my code on Chrome while developing, but for deeper testing and debugging I rely on Firefox Developer Edition, which is not available in Debian’s repositories.

For everyday browsing I also like to use the non‑ESR release of Firefox, which Debian does not provide either. You can download Firefox from Mozilla and make a custom GNOME launcher pointing to its executable, but that approach lacks the convenience of a proper repository. I wanted a solution that gives me both non‑ESR Firefox and Firefox Developer Edition via APT.

1. What Versions of Firefox Are

Here’s a quick overview:

• Firefox Developer Edition: a version designed for developers, with advanced dev tools and experimental features.
• Firefox ESR (Extended Support Release): stable, supported release with long‑term security fixes.
• Regular Firefox (non‑ESR): the latest full release with all new features.

2. Step by step installation

2.1. Create the APT Keyring directory

First, make sure APT has a place to store repository keys:

sudo install -d -m 0755 /etc/apt/keyrings

This directory will hold the signing keys for the Mozilla APT repository.

2.2. Import the Mozilla APT repository Signing key

Download and save the key that will let Debian verify Mozilla packages:

wget -q https://packages.mozilla.org/apt/repo-signing-key.gpg -O- \
  | sudo tee /etc/apt/keyrings/packages.mozilla.org.asc > /dev/null

This ensures that packages you install from Mozilla’s repository are authentic and not tampered with.

2.3. Check the repository signing key

Here’s a simple command to check that the key you downloaded matches the official one online:

LOCAL_HASH=$(sha256sum /etc/apt/keyrings/packages.mozilla.org.asc | awk '{print $1}')
ONLINE_HASH=$(curl -s https://packages.mozilla.org/apt/repo-signing-key.gpg | sha256sum | awk '{print $1}')
[ "$LOCAL_HASH" = "$ONLINE_HASH" ] && echo "✅ The key matches" || echo "⚠️ The key does not match"

Repository signing keys are used to verify the integrity and authenticity of software packages, making sure they truly come from Mozilla and were not modified in transit.

2.4. Add the Mozilla repository

Tell APT to also look for packages in Mozilla’s official repository:

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" \
  | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null

This enables Debian to fetch Firefox (non‑ESR) and Developer Edition from Mozilla’s maintained packages.

2.5. Give prority to Mozilla packages

Optionally, configure APT so that packages from Mozilla are preferred over Debian’s defaults:

echo '
Package: *
Pin: origin packages.mozilla.org
Pin-Priority: 1000
' | sudo tee /etc/apt/preferences.d/mozilla

This makes sure that when you install Firefox or updates, APT will use the Mozilla repository instead of Debian’s archives.

2.6. Install Firefox and Developer Edition

Now update APT and install the packages:

sudo apt update -y && sudo apt install firefox firefox-devedition -y

You will now have both the regular non‑ESR Firefox and Firefox Developer Edition available.

2.7. Install language packs (optional)

You can install a language support like that:

sudo apt install firefox-l10n-fr firefox-devedition-l10n-fr

This gives you localized user interfaces for both browsers. 

✅ With this setup, Firefox and Developer Edition will be updated automatically by APT, just like any other software on your Debian system.

1. The ideal device and accessories

Ideally, you should use a DSLR or mirrorless camera (APS-C or Full Frame). If you have a bridge or compact camera, make sure it has an Aperture Priority (A or Av) mode so you can adjust the aperture (F-number). Without this mode, achieving the background blur effect will be more difficult, but you can compensate by removing the background in post-processing.

A tripod is highly recommended: position it at face level.

Quick tip: have some tape, a tape measure, and a marker handy to ensure you’re properly positioned.

📍 Where to draw which reference point?

It’s time to measure:

1. Place the tape measure on the floor, starting from the wall that will serve as your backdrop, and measure 2.5 to 3 meters. At this point, stick a piece of tape to the floor and draw a mark with a marker. This will be your reference point for positioning.
   
2. From this mark, continue measuring another 2.5 to 3 meters. At this point, place a second piece of tape: this is where you will position the tripod and camera.

2. Prepare your environment

Ideally, you’ll need a fairly deep room (5 to 6 meters deep). The back wall should be a solid color: white, light gray, or black. Avoid bright colors that might draw attention: you are the subject.

If possible, position yourself near a window, either directly in front of it or slightly to the side to benefit from natural light.

⏱️ Activate the timer

Ten seconds is perfect for giving yourself time to position yourself. If you have a remote control, it can be handy, but make sure it’s not visible in the photo.

Stunivers

A flash can be useful, even during the day, to eliminate shadows on the face. If it’s too powerful, it can be counterproductive. Remember to test the results.

The settings

Stunivers

• Camera positioned about 6 meters from the wall, with you standing 3 meters away, or at least between 2.5 and 3 meters.
• Recommended focal length:
  • APS-C sensor: 50 mm (or zoom lens set between 40 and 60 mm).
  • Full Frame sensor: 80 mm (or zoom lens within this range).

⚙️ Technical settings

• Aperture: Set to the widest aperture (e.g., f/1.8, f/2.8) for a nice background blur effect.
• Orientation: Portrait mode (vertical).
• ISO: Take several test shots to avoid photos that are too dark or too bright.
• Focus: Single-point autofocus, with the focus on you, to clearly separate your face from the background.

4. Clothing and accessories

✅ Opt for simple, professional clothing (the kind you would wear to an interview).
✅ Favor solid colors: navy blue, gray, black.
✅ Avoid bold patterns or flashy accessories.
✅ Be mindful of white backgrounds: a white shirt on a white background can be problematic (you risk blending into the background).

5. Pay attention to your posture and expression

A natural posture and expression are essential for inspiring confidence and dynamism in your CV photo.

🧘‍♂️ The Right Posture

✅ Stand up straight, but not rigidly: too stiff, you’ll appear tense; too relaxed, it can give an impression of nonchalance.
✅ Shoulders slightly back and spine straight. Straighten up slightly more than usual to project an impression of openness and confidence.
✅ Avoid crossed arms, which can give an impression of closed-offness. Leave them relaxed at your sides or rest one hand on top of the other naturally.
✅ Tilt your head very slightly (a few degrees) for a more engaging effect.

🎭 Working on Your Expression

✅ Look directly at the camera, as if you were talking to someone, to make your gaze feel more engaging.
✅ Smile gently, without forcing it: a smile that’s too broad can look artificial.
✅ Think of a pleasant or funny moment to trigger a natural smile.

📌 Personal tip: I tested it on a textured wall, and the background blur completely smoothed it out, making me stand out perfectly from the background.

6. Retouching and cropping

✅ Crop if necessary to center your face with a little space above your head.
✅ Light retouching only: adjusting the lighting or removing imperfections is acceptable, but the photo must remain true to life.

7. Miscellaneous advice

Here are some tips for practicing this exercise:

✅ Take several photos to have options.
✅ Try different poses to see which one best showcases you.
✅ Check the final image: make sure it reflects the message you want to convey to recruiters.

8. Format and dimensions

✅ High resolution: for a clean and sharp image.
✅ Recommended format: square or slightly elongated portrait.

This is Stunivers. A space where logic meets creativity, where technique and imagery intertwine, where every problem deserves a solution.

Who am I? Stéphane. But call me Eoran.
I used to be a technician. I am a developer. I explore photography. Music accompanies me as much as code. And I have this persistent tendency to want to understand how things work. Not superficially. Not in theory. Deeply. Until every detail makes sense.

This is why this blog exists: to put into practice what I learn, and to share what I discover.

Why Stunivers?

Because here, everything is open to deconstruction, analysis, and improvement. Because some questions remain unanswered. Because there are always paths to explore, ideas to test, failures to understand.

The web is full of information. But often, it only scratches the surface. Or it dives deep into topics that don’t concern me. Sometimes, I dig. I search. I experiment. Because… why not?
When a problem resists me, I don’t give up. And when I find a solution, I share it.

Because this knowledge deserves to be open source.

What to expect?

No long-winded theories without practical application. No empty content that wastes your time. Here, everything revolves around experimentation, technique, and creation.

Tech. Code. Photo. Music.
Practices, reflections, solutions. But also failures. Because that’s the only way to move forward.

I go all the way. Some topics deserve detailed analysis. Others only need a short post to present an idea. Everything evolves. Everything improves. You’ll find series, explorations, and firsthand experiences here.

And after that?

This blog is a first step. A playground. A laboratory.

The goal is clear: to go further. A YouTube channel, perhaps. Other formats, certainly. The medium doesn’t matter as long as the message gets across.
