Angry Canada Goose

Male Canada geese are very aggressive. During mating season they choose a female (if they do not have one, as they are monogamous) and defend her (and later the nest) against all rivals (even other species).

This scene started with a couple sleeping at the edge of the pond, when suddenly a second pair loudly came swimming across to chase the couple away. The couple did not budge, and instead it lead to a long fight about whom the pond belongs to. I was standing right next to them, and they were a) loud and b) scary!

Olstinden Mountain

Olstinden is a prominent 675 m high mountain in the south of the Lofoten Islands in Norway. We saw it from the car on the way to the next campsite, and I just had to stop and take a panoramic photo.

This panorama was created from two photos.

Half Moon

The sunlight beautifully catches on the rims of the waxing crescent moon's craters.

This image was stacked from 20 individual photos. The process was similar to an earlier attempt (see https://www.picturavis.com/picture?/253/), except that I converted to JPG at the very end.

Creeper on a tree

Treecreepers can be found in forests flying from tree to tree looking for insects. They are very good climbers and often start further down on a tree trunk, working their way up. Their coloring can make them almost invisible on a tree if they stop moving.

Abstract Winter Bokeh

Melting snow and ice can create a beautiful light show when combined with the backlighting winter sun.

Stacked Moon

First, I wish you all a happy new year! The Fediverse is awesome and you are all awesome!

This is my first attempt at creating a stacked moon image. The moon was a bit low, so there is a lot of "wobbling" in the images, making perfect registration of craters difficult. After some quick research and trial and error, I settled for the following workflow:

  • Batch processing of 14 individual RAW files with RawTherapee to JPEG
  • Manual cropping around moon for each image in GIMP
  • Nonrigid registration of all photos onto first image in Fiji via bUnwrapJ
  • Second nonrigid registration via Align Layers from G'MIC in GIMP
  • Stacking of all 14 images into one image via Blend [Average All] from G'MIC in GIMP
  • Sharpen via Sharpen [Gold-Meinel] from G'MIC in GIMP
  • Contrast and saturation processing in GIMP

Any feedback and suggestions are very welcome!

Nuthatch in Snow

We got some early snow this year, so I took the opportunity to get a shot of the nuthatch in our garden.

Nun arbeite ich doch schon einige Zeit unter Linux mit Software für die Fotografie.

Eines dieser Werkzeuge ist digiKam und dazu hab ich nun einen Erfahrungsbericht geschrieben:

Winged Spoon

The spoonbill is a striking bird with a long spoon-like bill that makes it easily recognizable from a distance. Depending on the specimen, it is as large or slightly smaller than a white stork or grey heron, but has shorter wings than either. Although its biosphere is shrinking, it is not considered endangered.

Dawn

Taken at the Reindeer Lodge near Jukkasjärvi, Sweden. A beautiful place, but unfortunately without reindeer in August. They do not like the mosquitoes. Neither did I.

Why is this flower not called a "sun(set)flower"?

I am very satisfied that I last year changed to digiKam to manage my photos.

Not only that it is a free and open source software (donations are welcome from us users) and available on "all" platforms (Linux, Windows and macOS). It is also a very competent software!

Galactic Tree

This image is a composite taken during the peak of the Perseid meteor shower on the 13.08.2023 at a remote location near Göhrde in Germany. It consists of 14 photographs of the Milky Way stacked with #Sequator. 3 additional photographs of the same scene captured meteorites that I added with #GIMP to the final Milky Way image. The single image processing was conducted in #darktable .

Dune Sunset

The Nationaal Park Duinen van Texel beautifully demonstrates the formation of coastal dunes. From the flat plane of the beach to large and completely overgrown dunes further inland and everything in between.

Thank you all for your likes, boosts and comments. I really appreciate each and every one of you! And thanks to all of you who contribute to any #FOSS projects. Without tools like #digikam, #darktable, #RawTherapee, #GIMP and of course #pixelfed my #photography workflow would not be possible.

Blue Mountains

I got up very early to photograph the sunrise from the local mountain top (Glander, 1883 m). It was a hard hike up in the dark to get there in time. Unfortunately it was very hazy and the sunrise was behind clouds, but the view was still worth it.

Snowfinch

Living high in the Eurasian mountains, the snowfinch is a larger relative of the sparrow. It is quite fearless and can be found around huts and lodges, scavenging for leftovers.

View from Plose

The Dolomites have many beautiful views. This one is easily accessible via the Woody Walk on the Plose east of Brixen.

Panorama processed from 5 photos.
