“Kostek is an outstanding videographer and photographer. I was lucky to have him capture and create a short film about my freediving journey. What’s more, Kostek was deeply involved in conceptualising the entire project. I was truly stunned when I saw the final result. I love what he creates—his underwater photos are exceptional, but his videos are simply WOW. I genuinely hope we get to create more together in the future. Thank you for bringing so much underwater beauty into the world, Kostek”.

MARIA BOBELA – World Champion Freediver, 30x polish national record holder, freediving coach

“Kostek is a brilliant videographer who captures emotion and focus in every shot, making each project feel unique. His professionalism and top-tier equipment shine through in every production.
For the past three years, he’s been the official videographer of our AIDA Freediving World Cup, consistently delivering fresh, high-quality work—no matter how similar the job.
It’s just a shame he didn’t film me at the closing ceremony”.

ALICE CATTANEO – owner of Freediving World Apnea Center

“Working with Kostek feels effortless… and the photos are stunning.
He was there the whole day during one of my workshops, but I honestly forgot he was. Then I saw the photos: he had captured the most iconic, symbolic, and precious moments. He didn’t just take great shots, he translated the energy, message, and precision behind how I teach. I used them on my website, and everyone comments on how beautiful they look”.

“Kostek’s professionalism is refreshing—he delivers on time, with clear, organized work and valuable creative input. His quick ideas and fresh angles made collaboration easy and enjoyable.
The final product was polished, high-level content that drove sales from day one. Having worked in London’s creative industries, I can confidently recommend Kostek—he delivers top-quality results, always on time. (Also, he looks great in a swimsuit—such a shame Kate snapped him up so quickly)“.
