Koi fish pond – HD pinhole video with Panasonic Lumix DMC-GF1 and Skink Pinhole Pancake

mit der relative kurzen Brennweite, ist die Lochblende lichtstark genug, um mit einer spiegellosen M4/3 DSLR Lochkameravideos zu drehen. Dieser kurze Film wurde mit der Lumix GF1 plus Skink Pinhole Pancake Objektiv erstellt, die resultierende MTS Datei anschließend in Nero Multimedia Suite 10 konvertiert.

with a relatively short focal length, pinhole apertures are bright enough to allow taking videos with Micro Fourthirds mirrorless DSLR cameras. For this short movie, a Skink Pinhole Pancake with pinhole was attached to a Panasonic Lumix DMC-GF1. The resulting short movie was converted from AVCHD format for the web using Nero Multimedia Suite 10.

Spinnenlilie mit Skink Photonensieb “soft glow”

by Juergen

Dieses Foto zeigt recht deutlich, wie das Photonensieb “soft glow” mit kontrastreichen Motiven umgeht. Die weißen Blüten der Spinnenlilie stehen in direktem Sonnenlicht. Die Konturen der Blüten erscheinen weicher als die grünen Blätter im Hintergrund. Die siebartig angeordneten Ringe des Photonensiebs bewirken einen ausgeprägten Haloeffekt

this shot is a very good example for demonstrating how the zone sieve “soft glow” works. The petals of the spider lilly are standing out against the darker background. The zone sieve creates a strong halo effect on the contrasty bright petals of the flower.

Skink Zone Sieve “soft glow” HDR photo

by Juergen

yes, taking zone plate and zone sieve images is exciting. With a digital camera it is easy too. I found that exposure bracketing, with at least three exposures to choose from, works better than just relying on the camera’s measurement. Sometimes, slightly underexposed zone images let the highlights stand out nicely and put a soft glow around brighter areas. However, it is also possible to combine a series of photographs into one HDR (high dynamic range) image.

To achieve this you can either use Photoshop or more specialized applications which do just this. Here I have used Photomatrix Pro 3.2. to combine five single images into one and fine tuned the result in Photoshop.

“frangipani im wind” – (photonensieb)

by Juergen

das Photonensieb für Micro Fourthirds Kameras (19 Zonen f42) erzeugt Bilder mit weichem Charakter und ausgeprägtem Haloeffekt. Bei dieser Aufnahme werden einzelne, im Sonnenlicht leuchtende Frangipaniblüten mit der Kamera eingefangen, die sich klar von dem schattigen Hintergrund der Baumkrone abheben. Die relativ lange Belichtungszeit (1/6 Sek.) und Windbewegung sorgen für zusätzliche Unschärfe.

gazebo sunset

by Juergen

in some situations it is impossible to measure or calculate the “correct” exposure and you have to rely on your luck and intuition. Here the camera was aiming against the setting sun with partly illuminated interior and and brightly lit exterior.

Lilly Pond with zone sieve “impressionist”

by Juergen

After a lot of experimentation with zone sieves on Leica rangefinder cameras, I found that this one works best. Under normal lighting conditions without high-contrast or reflective areas, the zone sieve will just behave like a pinhole, just a little softer. Pronounced highlights and visible halos only appear when the available light becomes stronger and contrast increases.Skink Pinhole Pancake
Focal length/ zone sieve distance to film: 24mm f/71
Zone sieve: “Impressionist”
2 clear dotted zones around main zone with size 0.218 mm
Angle of View: 84° just as wide as an Elmar or Summilux

Film: Fuji Superia 200
partly overcast afternoon sky

the zone sieve used has only two clear concentric rings with small circles.
