Questions about the subject, usage, technology & more
What are the small square holes along the edge of a film strip called?
The small rectangular holes running along both edges of a film strip are called perforations or sprocket holes. Introduced in the 1890s, they allow the camera and projector mechanisms to advance the film precisely frame by frame. On standard 35mm film, each frame is flanked by four perforations per side, a specification standardized by the ISO 1007 norm.
How can this photo be used?
This stock photo is well suited for agencies, publishers, and creative studios integrating analog visual language into campaigns, book covers, or magazine layouts. The commercial license on Kataloop allows broad usage, including promotional materials for photo labs, film schools, archive services, or cultural projects. The 8640 x 5760 pixel resolution also supports large-format print production.
What mood does this photo convey?
The combination of warm brown film tones and the cool white of the ribbed glass creates a calm, matter-of-fact contrast. Selective focus draws attention directly to the perforations while the background softly fades away. The image feels focused and analytical, with a subtle nostalgia inherent to the analog medium itself.
What equipment was used to capture this photo?
The extreme detail in this shot comes from the Sony Alpha 1 (ILCE-1) and its 50.1-megapixel sensor, capturing every film perforation at 8640 x 5760 pixels. The Sony FE 24-70mm f/2.8 GM II at a wide aperture creates the distinctive shallow depth of field that separates the film strips from the blurred background, adding a three-dimensional feel to the image.
What visual style or trend does this photo represent?
Analog aesthetics are experiencing a broad revival in visual communication. Film strips, grain, and handcrafted photographic processes signal authenticity and a slower pace, a counterpoint to digitally smooth perfection. This image also serves the growing demand for archival aesthetics in cultural projects, documentary design, and the marketing of creative professions.
