Tampere Photo festival 2025

Some of pages still have Finnish description only, but photos are the main point anyway. Translations coming in future...
360° panoramas and artwork
A 360° photo is a horizon-spanning panorama that captures the entire environment perceived by the camera in every direction, including straight up and down.
The photographic works on this site are produced from these 360° images using projection methods that allow a 360° environment to be presented on a two-dimensional surface—somewhat like cartographers project the spherical Earth onto a flat map using various mathematical projections. More information about image projections is provided at the bottom of the page.
In addition, the aim is to keep the works visually engaging and to find artistic perspectives in real-world subjects.
The photographic works have been accepted into the exhibitions listed below.
Scandinavian International 2025
Scandinavian International Exhibition of Photography 2025 is a photography exhibition for creative images (Creative section), organized by the Malmö International Photo Society. Two of Teemu Sipilä’s photographic works were accepted into the exhibition, one of which also received an Honourable Mention in August 2025. Learn more on the exhibition page!
17th Finland International Digital Circuit 2025
Two photographic works by Teemu Sipilä were accepted into this international exhibition, which was organized under the coordination of the Finnish Association of Camera Clubs as five circuit exhibitions hosted by different camera clubs. For more details about the accepted works, see the accompanying exhibition page and the organizers’ results announcement (10 July 2025).

Tampere Photo Festival 2024
Sunsets in 360 degrees, a photo series, was exhibited at the Tampere Photographic Society’s Photo Festival in September 2024. It featured two 360° panoramic photographs and two images rendered in a “little planet” projection.
Spherical panoramas
The site’s spherical panoramas (tiny planets) are mostly produced by projecting a high‑quality photograph captured with a 360° camera into the so‑called “little planet” or "tiny planet" image projection. In this way, the entire 360° horizon appears along the rim of the image’s sphere. The camera’s location and its immediate surroundings are in the center of the frame. Any clouds and the sun at the moment of capture appear beyond the rim.
More precisely, this “little planet” projection is a stereographic projection. Its inverse is the so‑called “rabbit hole” projection, which in turn wraps the camera’s immediate surroundings onto the rim and places the horizon in the center. Autumn swirls is an example of such a work.
In the series Open air museum in autumn photos 1 and 2 are “little‑planet” spherical images, and image 3 is projected in the “rabbit‑hole” form. Both projection types are also used in the images of the Spherical panoramas in autumn exhibition.
In addition to the two projections mentioned, 360° images can also be presented in two-dimensional form in many other ways. For both the Bomarsund ruins (panorama above) and the Kutala Casino (below), you can view both spherical images and full-horizon panoramas.
Image formats and prints
The image files published on the site are saved at typical web image resolutions (such as 1280×1280 pixels in JPEG format), which are well suited for showcasing the images.
The original 360° photographs, as well as the spherical panoramas and full-horizon panoramas produced from them, are also available in significantly higher resolutions, enabling the production of high-quality prints and photo panels.
For example, the photographic works in the Spherical panoramas in autumn exhibition were printed on high-quality white cotton-based fine art paper (Hahnemühle Photo Rag 308 gsm), which is one of the most popular matte FineArt photo papers for inkjet printing. An Epson SureColor SC‑P900 photo printer was used, offering excellent print quality thanks to its 10‑color ink system. The same high-quality printing method was also used for the Photo Festival 2025 photo prints.
Generative AI and image editing
Some works may appear abstract due to the effects of image projections. However, the image content depicts real landscapes captured by a 360° camera. No generative AI has been used to produce image content in the photographic works on this site.
Image-editing functions have instead been used to improve the technical quality of the images. In addition to the previously mentioned projections, this includes, among other things: stitching images exposed through the approximately 200° lenses on both sides of the 360° camera; using AEB/HDR techniques (the camera takes 3–5 shots at different exposures that are merged into one to improve dynamic range); removing the tripod or possible lens reflections visible in a 360° image (cloning); adjusting colors and texture; sharpening; and noise reduction.
360° experiences
Naturally, 360° images can also be viewed more freely in various interfaces. For example, in a browser, on a smartphone, or with VR headsets, you can freely change the viewing angle while exploring 360° images. On this site, most examples are static representations of 360° images.
However, some pages also include an embedded interactive 360° viewer, which allows you to view the scene all around you using VR headsets. For example, you can explore the Kutala Casino and Photo Festival 2025 images through 360° experiences, as well as the Turku Castle presentation shown below.
