Finally on water again … Korsar sailing
Finally shooting some sailing again last weekend – puuhh wasnt perfect in terms of conditions /not much wind/ but huuu great to be out there again do some graphical visuals. The Korsar training was one of the first events on water here in Berlin – though the OptiAB kids were first. Some shots here – likely no full gallery...
MicroSD cards and standards …
There is a lot of confusion about the speed of MicroSD cards these days and various standards exist. Overall its easy to buy yourself into the wrong card type and for copter data acquisitions with the P4Pro the card speed is essential. So here we go: UHS-I and UHS-II (Ultra High Speed Classes): UHS-II is the newest standard but is...
Speeding up Agisoft Photoscan
For some of the copter data processing folks Agisoft Photoscan turns out to be the most important tool/software to calculate point clouds, orthoimages and nadir data mosaics from copter photographs. Problem: very long processing times with dense point cloud calculations with high or ultra-high settings (full resolution image matching with SfM (Structure from Motion) algorithms). Some nice net finds show...
Drone Deploy and DJIs POI Mode copter image acquisitions
Using DroneDeploy and the POI mode of DJI (this article was first published on jenacopterlabs.de). Have been doing some leaf-off flights now in March on one of my favorite sites for complex tree crown point cloud mapping. To add to the leaf-on data from last autumn. Fig.: Leaf-Off point cloud with combined height color coding and reflectance color coding. This time...

Schlachtensee Panorama
The higher resolution version of the Schlachtensee Pano shot / panorama from early February. This was a magic week. Temperatures and light were just perfect and the ice was incredible untouched. This pano is from the P3A. For those not familiar with the Berlin south west. The Schlachtensee region is known in Berlin as the area where the people who...
International Swim Meeting Berlin 2017
Spend the last weekend at the International Swim Meeting 2017 – shooting a swim event. Pretty complex conditions but some nice shots are now online here: http://soeren.zenfolio.com/ism17 The challenge clearly is A. to get the timing right (varies with the different swim styles/techniques), B. to be at the right position for the different styles, and C. get all the participants covered...
Phantom 4 Pro Flare Tests
Did some more tests with the Phantom 4 Pro: The into the sun shots just capture a lot of flare and the sun star is very much Samyang 14mm like. This is an issue and it reduces the image acuity for 3D point cloud modeling for object measurements as well as for the landscape panorama approach. The against the light...
Phantom 4 Pro Tests
Have done some tests with the new Phantom 4 Pro that I am using in 2017 for some research projects on photogrammetric point cloud mapping. This is a remarkable step forward in terms of image quality. The Phantom 4 Pro just creates much better image detail and acuity and resolution/sharpness is on a much higher level compared to the Phantom...
Yacht and Regatta Photography
Some thoughts I wrote down originally for the KLASSIKER Journal (4.2016) of the FKY. “Gedankensplitter zur Yachtfotografie. Die Visualisierung dieses Spannungsbogens von Wind, Wetter, Wasser, Yachten und dem puren Segelsport ist an Vieldimensionalität kaum zu überbieten. Kaum ein Sport ist so stark abhängig vom Wetter, vom Wind, von den äußeren hochvariablen Bedingungen. In der Wandelbarkeit des Wetters und damit...
