The steadicam

“The steadicam is a mechanical gadget that allows us to move the camera with a great freedom and smoothness.
Operating a Steadicam requires an understanding of how the instrument works, plus the development of a set of special skills to make the Steadicam move exactly when, where and how desired.”

– Jerry Holway e Laurie Hayball, The Steadicam® Operator’s Handbook

«I was born on August 20th 1981, in Lisbon, Portugal.  I was drawn early in life to photography as my father’s hobby was photography and shooting super 8 films.

Because we were inseparable, I would spend hours in his amateur lab, going through magazines, exploring his photographic equipment and looking at his super 8 home made films and so… even before I could read, the magic of cinema had encroached upon me.»

Samuel Amaral  graduated in Cinema, Television and Advertising at the IAT – «Training  and Research Institute for Media and Comunication Technology – Universidade Moderna (2001-2004)

In 2003, during his Training, was invited to accept the function of “Steadicam assistant” which he performed in advertising, films, shortfilms, documentaries and music videos. That’s officially, how he came under the spell of motion pictures.

In 2005, he worked as camera assistant in two epocha series: «Quando os Lobos Uivam» and «Pedro e Inês».

In 2006, started his activity as Video Assistant in his first feature film: « Do outro Lado de Mim»

In 2008, he was admitted at “Planar” – Camera Rental House. He entered the job market as Video Assistant and later on as Image Assistant, having participated in a variety of renowned national and international  productions.

In 2016, in order to improve his technique, participated in Germany in the 25th International Steadicam Workshop and Electronic Stabilizer Simposium, with Masters, such as, Larry McConkey, Peter Robertson, Nicola Pecorini, Patrick De Ranter and Jorg Widmer.

Later in 2021, in the midst of the pandemic, and more recently in 2022, Samuel was invited to Egypt, where he performs in several projects like Netflix series and Synergy series, amongst other commercials.




TRINITY is the first hybrid camera stabilizer that combines classic mechanical stabilization with advanced active electronic stabilization, provided via 32-bit ARM-based gimbal technology. This combination results in five axes of control and enables uniquely fluid, wide-ranging, and precisely controlled movements for unrestricted shooting and total creative freedom.
New angles for the operator and new storytelling options for the director and cinematographer are possible with TRINITY. By inverting the post, the camera can be moved from low mode to high mode during a shot; using the joystick-controlled, fully stabilized tilt axis to look up or down during this motion is also possible, so a low angle can smoothly transition into an over-the-shoulder shot. By holding the post at 45 degrees and twisting it left or right, the camera can even look around corners, whether in low or high mode. Additional stabilization in the roll axis permits the use of telephoto lenses. Extraordinary new shots, angles, and movements are achievable when TRINITY is used in its fully stabilized mode. For situations that call for a more traditional operating style, TRINITY can be switched into a locked mode in which the tilt axis is connected directly to the post in the traditional manner.
