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...

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...

400mm at its best – shooting the background-blur-king

The mother of all lenses: the Nikkor AFS 400mm f2.8G VR ED This is one of the lenses that most serious sports photogs have in use regularly. Its THE bread&butter lens of the soccer/football/car racing and swimming/athletics sports photographers. This is a really heavy lens (4.62 kg) and even if you come from a 300mm f2.8 lens design, the size...
