Aerial photography

It’s a new approach to photography for a photohrapher, when using a drone. Before starting for the flight, the photographer should at least have an idea about the possible perspectives, from which his copter shall capture the photos. This requires the ability of a three dimensional imagination. Unlike in the regular photography, the drone pilot does not see the scenery with his own eyes. Only a stepwise experience allows him to guess, how a forest and meadow landscape might look in a bird perspective at a level of 50 or even 100 m.

But despite of all three dimensional imagination abilities and experiences, much photography or videography is based on spontaneous shooting reactions, based on the transmitted live picture.

If full automatic camera modi shall be avoided, manual presettings can already be made before starting the flight according to the general light conditions, finer adjustments can then follow in each specific case, when the drone is in the air.

An aerial photographer needs to resist to the danger of perceiving the environment in top-down view after some time with the drone camera only. The German laws define that a drone is only allowed to be flown in a distance of a direct visual contact. One reason is that one otherwise losses the feeling for a safe controllable space limit.

Before drones as flying cameras became commercially available for everybody, aerial photos or videos needed to be captured under more risky and also more costly conditions. Smaller planes, manned helicopters or cameras on balloons needed to take over the same function.

Being able to fly like a bird under remote control conditions is freedom for the spirit and at the same time freedom for an incredible creative flexibility.

Landscape

All aspects of our world deserve being considered as drone photography motifs (respecting laws of course) . Whether a settling, a city, a street construction, people, architecture or nature sceneries, the drone technology enables new options and aesthetic experiences. I made experiences in different photo object types (the respectation of laws has always a priority). But for my own projects I prefer landscape, weather, season and art photography.

Flying in more or less remote areas with natural landscapes reduces the probability that a drone accident might harm people or architecture. But it is of course additionally important to bring no animals or plants in danger.

Landscape photos are the more interesting the more complex their composition is. But a forest with adjacent meadows is per se no guarantor for an impressive photographic piece of art.

Only the contrasts of colors, shapes and different landscape elements can under optimal conditions create complexity and a fulfilling picture composition. More or less sharp edges between for example forest areas and adjacent meadows might built up an impressive and even seemingly abstract pattern, making the shot to a fascinating piece of art.

Season

City structures, such as architecture, streets or walkways, seem not to underlay bigger seasonal changes (in times withoug snow or rain) . Is that true? It of course is not, the seasonal different light conditions always cause different photographic or videovraphic looks of the same location. The lack of intense green or colorful vegetation spots in between creates additionally sceneries with very different moods.

Of course the effect of different seasons is especially distinct in the nature photography. Even in case that black and white photos would be preferred, leafless trees of a winter forest usually look remarkably more interesting than an amorphic mass of grey leaves. In the colored drone photography, nobody would doubt that the diversity of autumn colors allows a much more impressive composition of structures, shapes and lights.

But also in summer or spring, when only slightly differing green nuances dominate the sceneries, eye catching drone photography can be performed.

In case the greenish landscape sculpture itself does not allow a photographic highlight, then a dynamic sky can prevent the whole photo from getting lost in a boring piece of sadness.

One needs to keep in mind that a positioning of the drone camera with being for a longer time straightly directed into the sun might harm the camera sensor. Against the light photography can look stirring, but it’s often of advantage to avoid the sun body itself completely. Against the light photos usually lead to dark landscape elements in the foreground, almost consisting of silhouettes only. To receive more details on the photo it is recommended to record a higher amount of information. Raw files can be the best choice in this context, as they allow to develop details during editing, which were not visible before.

Editing

To become able for an improving editing of a photo, a minimum resolution of details should be available. A resolution of 20 megapixles or more offers enough buffer for art filters or manual changes of light, color, contrast etc. The Mavic 2 Zoom for example unlike its sibling brother Mavic 2 pro with a high quality 20 megapixles camera, offers different panorama modes. One of them is created as composition of several 12 megapixle photos, which the camera automatically puts together to a 45 megapixle piece. In case drone cameras allow a raw mode and additionally a high resolution, both of these options should be chosen.

Editing can have different functions combined with different intentions of the photographer. An almost perfect photo sometimes needs being only slightly digitally improved. Alternatively the entire photo might need to be stronger modified for aestethic and creative reasons to create the planned piece of art. The creativity of the photographer and editor at this has no limits, but it should be tried to avoid the ‚killing‘ of too much picture information.

Not every editing tool has a modern high quality level. Lightroom, Photoshop, pixlr and similar software of other developers must be recommended.

Countryside of Berlin: urban green in a drone view (4K)

Many tourists from overseas use to visit European cities in a much too short time. For this reason they often miss an entire picture of for example the city Berlin, when inserting an only short interstop here. Especially winter tourists can experience the German capital as a sad a grey urban being with some architectural major sites and a remarkable party life only.

 

Climate and landscape types in Berlin

 

Berlin has a continental climate and shows a completely other face in summer. It’s a very green face. Not only is the center of the city then colorfully greened by numerous urban parks, which partly lay almost adjacent to each other, but also the outskirts, in major parts covered by forests and grasslands or fields, appear like green oases.

Lübarser Felder and surrounding

 

Lübarser Felder is an area of agriculture, being under the management of inhabitants of the adjacent village Lübars, which represents the only Berlin village that still practices agriculture. The village has a long history and still has architectural monuments, dating back to the 19th century. Lübarser Felder lay adjacent to a nature refuge area more in the north, consisting of different kinds of wetlands, such as bog meadows or lowland fens. Lake Köppcensee as part of that nature refuge area is visible from a bigger distance in one scene of my video.

 

Püttberge and surrounding

 

The sanddune-mounts Püttberge are located in the east of Berlin and belong to the nature refuge area Wilhelmshagen-Woltersdorfer Dünenzug. The area consists of sandy mounts, some of them reaching a height of up to 68 meters. They are part of the glacial valley of Berlin, which dates back to the Weichselian glaciation, which happend between 115,000 and 11,700 years ago and covered almost the whole Northern Europe. The dune elevations of Püttberge were formed due to windblown sand inside the glacial valley. My footage shows the Wilhelmshagen-Woltersdorfer Dünenzug in a greater distance seen from the edge of the whole area. Ecologically the Püttberge are characterized by numerous plants and animals, being typical for sanddune environments.

 

Lieper Bucht at river Havel

 

Lieper Bucht is a bathing beach area at river Havel, belonging to the Berlin city district Nikolassee in the South-West of Berlin. The adjacent forest area is the huge urban forest Grunewald. The riverside of Havel in Berlin is geologically charactrized as sandy with a tendency to the formation of dunes, being like Püttberge a relict of the Weichselian glaciation. Flora and fauna are correspondingly composed. Pine trees for example are typical representatives. The nearby Havel islands Lindwerder and Schwanenwerder are visibe in my footage.

Lake Teufelssee in Berlin as part of a glacial meltwater lead

Lake Teufelssee in the Berlin urban forest Grunewald is known since ancient times, but is even much older. This is unlike the adjacent hilly landscape, which is named Teufelsberg („Devil’s Mountain““, referring to the nearby lake). It represents an area of mounds of rubble, built up with debris of the destroyed Berlin after the Second World War. Teufelssee („Devil’s Lake“) however is part of a glacial chains of lakes, a result of a supraglacial stream from the period of the Weichselian glaciation.

Geomorphology of Berlin, lake Teufelssee and glaciofluvial sands

 

Berlin itself represents geomorphologically a push morain from the Weichselian glacier times (until 11.600 years ago). This until today explains the uniform and scarce vegetation in and around Berlin, which is due to specifically sandy ground conditions. Sand layers with a thickness of at least 20 m date back to glaciofluvial sands, being a result of the advance of a glacial tongue.

 

Vegetation and climatic zone

 

The stock of trees in the Grunewald area is dominated by oaks and pines, being well adapted to this ground composition and the Berlin geomorphology. The climate of the Berlin area is characterized as part of the temperate climate zone in the transition between maritime and continental climate. Aspects of the continental climate are predominant, which is why snowy winters as typical for the Southern parts of Germany are rare.

Instead winters are often very cold and with low precipitation unlike the hot summers, where most rainfall occurs. The winter 2018 to 2019 is following an unusually warm summer with long periods of heat and without rainfall. As a result, water bodies Germany-wide carried less water than usually. But in which intensity lake Teufelssee was or is still concerned is unknown to me. Differences to former years are not obviously visible.

 

Berlin recreation areas and the ancient origin of the term „devil“

 

Teufelssee and Teufelsberg represent local recreation areas and offer enthusiasts and families with children a popular playground in summer, and in case the lake is frozen, also in winter.

The appearance of the German word for „devil“ in Teufelssee and Teufelsberg is assumed to refer to an ancient place of worship in this area.
