As part of the event Estonian Science Photographer of the Year 2017 was announced as the winner of the competition and this prize was given to Kertu Liis Krigul.

Other mentions were given in following categories:

Microscope photos

• 
  Winner: Photo of Scanning Electron Microscope where it can be seen how after 2 hours of heating at 600 °C silver with lower melting temperature starts expanding out of the shell of silicon dioxide. The photo was taken as part of research where the durability of the coil of silver nanoparticles by adding a protective layer. (Mikk Vahtrus)

Photo series

Winning series – Heli Lukner, Sandhra-Mirella Valdma, Andreas Valdmann

Authors of series studied how to create a suitable scattered light field with special diffuser and lens. As a light source a super continuum laser beam that covered whole spectrum of visible light and near-infrared. Changing the distance between lens and diffusor less or more sharp objects formed on the wall of laboratory reflecting from the lens, which were photographed.

General category

• 
  Winner: Photo of transmission and mixing of two flurescence dye in porous 3D environment. Refractive index of beads with 16 mm diameter is same as of water surrounding the beads, making it possible to visualize transmission and mixing of dye in the light of horizontal laser in porous environment. (Mihkel Kree)
• 
  Jury prize: Photo of bicolorana bicolor that was found for the first time in Estonia in 2015. This species usually dwelves in more southern areas and its discovery in Estonia is taken as a hint to global climate change. (Veljo Runnel)
• 
  Jury prize: Photo of diving bell spider and assellus aquaticus in Rahaaugu nature reserve. (Lennart Lennuk)
•
