Recently found this nice webpage where You can calculate the background blur of your Telelens-Camerasensor combination:

 http://howmuchblur.com

Very handy to get some ideas on how the isolation power of the various lenses behave in comparison. If You look carefully  the 400mm f2.8 and the 600mm f4 seem to create the most blur but its distance and background-distance depended. It also doesn’t tell you anything about the blur QUALITY and/or depth of field in that context.  If you however always choose the same size of your object/subject in your frame (modify the distance to the object with different lenses) and you keep the same aperture – the resulting DOF should be basically the same.

Anyways – the 400mm f2.8 looks really as if it is the blur king in these medium distances!

Brittany Selection Online

A selection of my 2014 Brittany shots is now online available under http://soeren.zenfolio.com/bretagne .

The coastline is full of remarkable spots for coastal/landscape photography. We travelled 4 weeks from Cap Frehel to St.Brieuc to Plouha, Paimpol, Lannion, Roscoff, Plouescat, and than towards Brest and Crozon.  Its one of these regions where it is a lot of fun to frame new perspectives although most of these spots have been photographed to death – there is hardly a coastal area in Brittany that hasn’t been photographed in stormy/twilight/foggy or in any other condition and at all times of the year in a professional quality and with lots of appealing concepts. But never less – its a lot of fun to travel this coast and photography always lets you experience colors and textures – nature in general – in more intense way imo.  You also get used to not only watch for the sun position but also for the tide rhythm. The appearance of this coast is very much dominated by the tide – to get the color of light /evening or morning light in tune with your preferred tidal situation can be very challenging.

12 mR in B&W

Eine Auswahl der 12er Bilder von 2015 ist jetzt in B&W in speziellem Grading zu sehen in der Galerie. Eine kleine Galerie mit Bildern die mir über die Monate für ein  B&W Postprocessing aufgefallen sind.

In SW zu editieren ist immer ein großer Spass, weil man viel mehr machen kann mit den Bildern, ohne das die Bilder an Glaubwürdigkeit verlieren. Das erlaubt einem ein viel stärkeren Eingriff in Kontraste und Helligkeiten als das bei Farbbildern möglich wäre.

Die Auswahl gibt es hier:

The AquaTech Elite sport housing - submerged and split level imaging concepts

Initial text upload: 15.11.2015 – by Sören Hese

1st update: 20.11.2015

Some comments about the AquaTech Elite sport housing that I acquired early in 2015.

This was on my list since some years but I never had the budget to do this. The situation hasnt changed much in that respect – especially since the Dollar/Euro ratio hasnt moved into the right direction to order lots of gear in the US.  After checking the market for diving houses it was obvious that I do not need a diving setup. These DSLR housings for diving are much bigger and heavier and rated for more water depth than “sports housings”. The latter are more for the near surface water sports (sailing, surfing, swimming, canoeing and so on). To go for the Aquatech housing was primarily defined by the supported lens selection. The 14-24 mm from Nikon was only supported by Aquatech as far as I was able to see online.

I used the gear for approx. 15 regatta sailing events now and also tested it for waves for 4 weeks and doing numerous shots in lakes. I can already conclude that its what you expect from a professional package and/or its elevated price point and its totally reliable.

To get a maximum of image sharpness and dynamic range I wanted my Nikon D800/D810 + Nikkor 14-24mm  combination in a housing concept – here you clearly end up with an ELITE sport housing from AquaTech.

After all its very hard to develop new perspectives in the domain of yacht and regatta photography – the split level approach isn’t new but it hasnt been used too much so far and there are lots of ways to develop new imaging ideas in this domain – from below water shots or split level shots and images that include the water as abstract art are often more appealing than shooting the yacht with the usual extreme tele lens setup. Help for reasoning is however that the housing can also be used to do more of the wave/water photography that I envisioned often when traveling the northern coasts in summer.

#Construction & Components:

So what is it? The AquaTech housings are not really designed for diving – the depth guarantee is for 10 meters. Thats not much if you are into diving. The AT housings are for waves, surfing and sailing. They are made for this transitional domain between the elements – between air and water – thats where the more graphical and more interesting stuff happens as light hasn’t been absorbed and water can play its sculpturing thing (sorry all you underwater photographer … although I found it pretty exciting to shoot in these clean lakes with lots of vegetation shadowing everything and creating a wild underwater vegetation land/sub-aquatic-scape ).

Construction is pretty much heavy duty with massive polyurethan housing construction, stainless steel controls, 10 mm acryl back-plate, durable aluminium tubes and 5 mm aryl domes, solid metal locking fasteners, interchangeable anodized metal lens ports with a knurled grip surface that makes it easy to tighten everything when mounting the ports. The grip surface is so knurled that you easily scratch everything you touch with the lens port. Overall „fit and finish“ of the housing with its snap fasteners and its big enough screws is just perfect. The setup screws together and is sealed with O-rings everywhere. Weight of the housing is 1.6 kg and the PD135 f.e. adds another 600 gr. Together with the pistol grip/pole extension and other accessories installed you easily reach 3 kg. The DSLR is mounted within the housing with an Arca Style plate that snug-fits precisely into the dove tailed Arca mount that is installed in the housing. The DSLR just moves exactly into place that way and the mechanical trigger of the housing sits exactly above the DSLR trigger.

Figure: Arca style plate setup that keeps the camera within the housing precisely in place.

Key for the functioning is an acryl dome element that is avail for a number of popular lenses. The dome construction is superb but it has one slighty anoying drawback. The sunstar of your lens is slightly distorted and not as accurate as when shot without the dome. If you like to use the sun star reflection as part of your visual concept sometimes – than this has to be taken into account. Overall sharpness and chroma aberration of  your lens isnt changed much imo. At least I couldnt find any difference in spatial resolution with the Nikon D800 NEF files after processing in LR. There seem to be some internal color reflections but its a minor issue and not at all comparable with the well known Nikkor 14-24 color reflection/flare issue at 14mm.

Segel-Saisonabschluss – leider …  könnte so auch rund ums Jahr weitermachen :), aber ist eindeutig sinnvoll auch mal Zeit zu haben hier und da Bilder “Reste” aufzuarbeiten.

Hier die Galerie zur “Rolling Home”. Passte diesmal alles. Irre Meldezahl bei den Folkebooten, klasse Licht und ausreichend Wind und Sonnabend dann die Beamershow mit einem BestOf der Bilder vom Samstag im SCA Clubhaus. Danke an Bettina Dittemer für die Zodiakfahrten  an dieser Stelle : – ) und die fixe Zusammenarbeit mit Angela vom Organisationsteam des SCA.

Das war dann doch mehr Aufwand als gedacht. Ist halt doch viel Material entstanden an den beiden Tagen und das Wetter war ja herrlich für die Weitwinkel-Shots in die Sonne. Die brauchen dann ja immer etwas mehr Korrektur und “cooking” im Post. Ende Oktober ist nun auf der Havel in Berlin auch das Wasser wieder recht klar, sodass doch recht gute “submerged” Kompositionen gelingen. Inzwischen klappen einige Kompositionen recht reproduzierbar –  einige der Probleme, die mich noch zu Beginn der Saison verrückt gemacht haben mit dem AT-Gehäuse sind nun Schnee von Gestern – zum  Glück.

Da mit dem Veranstalter (SCA) abgesprochen wurde eine Download Galerie zur Verfügung zu stellen, gibt es nun zwei verschiedene Galerien: eine Passwort geschützte Download Galerie (1400×900) und eine öffentliche Galerie mit Bildbestellungsoption für die volle Auflösung.

Die Mitzieher klappen etwas besser inzwischen und hab ein Faible für rote Spis entdeckt. Bei tief stehender Sonne geben die einfach einen herrlichen Kontrast zu blauen und grün-blauen Tönen – perfekt für die Halb-Unterwasser-Shots, die Spiegelungen in den Oberflächenripples sind einfach mit einem roten Spi besser zu erkennen und es gibt einfach viel besseren Farbkontrast.

Die “Rolling Home” Regatta – ausgetragen von meinem Segelclub – dem SCAhoi in Berlin – hat sich zu einem tollen Folkeboot Event entwickelt: 52 Boote am Start dieses Wochenende! Dazu herrliche Oktober Sonne und am Samstag auch schön konstante Windbedingungen. Da der Wind die 3Bf kaum überstieg gabs viel Spielraum zum Experimentieren. Hier eine kleine Vorschau. Für die teilnehmenden Crews gibt es diesmal eine zugangsbeschränkte freie Galerie mit allen Bildern  incl. Siegerehrung in etwas reduzierter Auflösung. Das Ganze sollte ab Mitte der Woche online sein.

Update: Full Gallery online: http://soeren.zenfolio.com/rh2015fullres   enjoy! Sören

Die Rolling Home ist ja traditionell für viele Segler in Berlin das letzte Event. Oft mit herrlichen Herbstfarben und Wind gesegnet – scheint es dieses Jahr zumindest mit dem Licht hinzuhauen. Wind ist mäßig vorhergesagt. Nachdem diese Veranstaltung in den letzten Jahren auch mal unter Nebel zu leiden hatte, kann man die Daumen drücken. Bilder dann demnächst wieder auf diesen Seiten.
