Out of focus - Day 70


Yesterday I did some corporate portraits using my AF 20mm f/2.8 and a SB-900 on-camera. At home flipping through the files in LR4 I was not satisfied with the sharpness of the photos - especially those photos shot at a distance to the subject and wide open (f/2.8-f/3.5-f/4.0-f/4.5).

So my assignment for today was to investigate if this could be true or if I was not able to hand hold a camera at an exposure time of 1/80 sec (and/or manage the flash output correctly).

The set-up was two identical lanterns positioned on a table against a wall in a wind free area. My Nikon D300 was on a tripod and release was done using a Nikon MC-36 cable release (highly recommendable). Obviously the lens was my AF Nikkor 20mm f/2.8.

Here is the original frame.


From there I shot a frame for each f-stop - (f/2.8/3.5/4.0/4.5/5.0/5.6/6.3/7.1/8.0/9.0/10.0/11.0/13.0/14.0/16.0/18.0/20.0/22.0). Instead of showing all those photos I have chosen a photo representing both f/2.8 and f/22.

 

It is evident that the f/2.8 is sharper than the f/22. The loss of sharpness occurred already at f/16. So the verdict over my blurred photos yesterday is clear. It was 100% the photographer's fault  - not the equipment ;-).

The final photo - at the top of this article - gas undergone carefull but extensive post processing in LR4.

x-teams

I've just ordered a new book from Amazon. The name "x-teams" immediately caught my eye as I read about it in the Danish business newspaper - Børsen. The reviewer assigned 5 marks out of six, so expectations are high.
X-Teams written by Deborah Ancona and Henrik Bresman raises an interesting question already on the front cover.
"Why do teams fail?"
The topic of the book is how to build teams that lead, innovate, and succeed. I'll write a short review as soon as I've read it.

Architectural Cubism - Day 106

A new office building in the northern part of Copenhagen. I'm getting more into architectural photography and with CS6 it is easy to correct "falling lines" perspective errors. The outer walls are forming a moire pattern when photographed. Imaging how this would look if I used a Nikon D800E instead of my old Nikon D300 :-)

Equipment: Nikon D300 with AF Nikkor 20mm f/2.8.
Exposure: 1/1000 sec at f/7.1, 0EV, ISO 200

Leder & Kommunikation

I juli 2004, da jeg var nordisk direktør for Bang & Olufsen, skrev jeg et kapitel til bogen "Kommunikationens mange ansigter".  Efter et veloverstået strategiseminar i sidste uge med min ledergruppe hos Strålfors Information Logistics, hvor jeg er administrerende direktør, så kom jeg til at tænke på denne tekst og fik lyst til at bringe den her på min blog, da budskabet fortsat er af største betydning for at lykkes med en strategiimplementering.

Der er fire grundpiller i kommunikation: Det verbale, det kropslige, det aktionsorienterede og det usagte. Der er også fire arketyper af modtagere i en moderne virksomhed: Individet, gruppen, personalet og det ophøjede individ. Uanset kommunikationsform og modtager så husk direkte, tydelig og ærlig kommunikation.

Kravene til en leders kommunikationsevner på jobbet er øget betragteligt over de sidste 10 år. Og ”jobbet” er her ikke ment i en snæver betragtning, men mere præcist det kommunikationsunivers en leder opererer i under u…
