dr. Concrete - an article
Rapid changes in the profile of social needs generated by development of industry affected also construction industry. Last 50 years brought to constructions new calculation methods, new safety standards and the need of fast and reliable structure adaptation to new situations. Developing industry connected with lack of care caused significant deterioration of existing infrastructure. All of those aspects caused sudden need of repairing or strengthening significant number of buildings and adjusting the others to new purposes, loads and safety standards. This need was realized by researchers in 1960s, and since that time many systems of strengthening repairs were invented. One of most effective proposals of strengthening bases on Carbon Fibers. While flexural behaviour of CFRP strengthened RC members is well recognised, torsional behaviour of such elements is almost unverified. Although prepared in 2001 fib Bulletin 14 treats briefly about torsion, basing on published in Swedish, researches of Täljsten dated 1998, but this area seemed to be generally neglected. That is why, in 1999, team of researchers from Silesian University of Technology, PL, decided to undertake the investigation program concerned on complex state of stresses with torsion influence included. Practice shows that problem of torsion in strengthened elements is essential in repaired bridges, edge beams, elements supporting overhead cranes and many others.

la luz de la mañana - from contact sheet to print
The "la luz de la mañana" photograph was taken in Merida, a town located in the north of the Yucatan peninsula of Mexico. It was taken from a museum building (with no glass windows). To be honest, I don't remember what the museum was all about. I was just staring down the street and enjoyed the perspective and the scenery. All together, I just exposed four frames from that location. Two of them were quite similar, with individuals just passing by. I felt that the one with the boy was worth printing, the composition was more balanced and I liked the white hat and that the car was more evident.
When printing this negative, I strived for dark shadows and a pitch black car. All in contrast to the white roof of the car and the white hat of the boy. I also felt that a high contrast print would make the road and the pavement more interresting. Furthermore, the early morning light would be more emphasised. Middle tones and blacks were obtained by printing at grade 4. To get a punch in the whites, the entire print was bleached until desired effect was achieved.
In a way, I must have had the photograph "fluteplayer" by Werner Bischofs unconsciously in my mind when I saw this scene in front of me. Perhaps, it's in the peacefullness, I see the resemblence. Sometimes telephone wires can ruin a good scene. Here, I'm grateful that they connect to the horizontal lines and make the image more alive.
Ansel Adams have said that the negative is the equivalent of the composer's score, and the print the performance. We'll see how I interpret the negative in couple of years from now...

Invited guest: Joannès Ceyrat
I have been photographing since 2002. At first, I mostly took pictures of friends and family, of events and journeys. Then, my interest in photography grew stronger. More and more pictures were being taken. I moved on to new subjects, new places.
My way of seeing evolved and the image itself took on new meanings. All of a sudden it was no longer the subject that mattered, but the image itself. I no longer took any pictures of friends and family, of events and journeys. Photography, for me, became a solitary activity, practised on long walks and bike rides along the outskirts of town - trying to find the right image.
After a long period of time, I stopped to wonder: why did it come to this? why did I evolve into neglecting photography's great potential to document, to keep track, to remember? Though I did not find any answers, my interest in photography changed.
Once again I wanted to take pictures of friends and family, of events and journeys. I had witnessed the potential of this kind of photography when I got to know Per-Arne Andersson. The birth of my sister's daughter was another important event. Also, being in a relationship meant that I took a lot more portraits - at least of one special person.
But how to make pictures of friends and family, of events and journeys, that could transcend the circumstances of their origin? How to make pictures that combined my longing for both subject and image - pictures that meant a lot to me, but were not dependent on what they meant to me, when looked at by other people. How?
I have not found the answer, not yet. But when I found the pictures of Joannès Ceyrat, I instantly knew that I had come very close. Therefore, it is my great pleasure to present some of his work here on the F blog.
This is what Joannès writes about his relationship to photography:
First there was the pleasure to touch the broken camera of my father: it's smell, the view from the viewfinder. Years passed ... and I really discovered photography in 2003 with my first digital camera. Then, the initial pleasure of old cameras came back with the buying of a 2.8f Rolleiflex, and then the wide 50mm one.
I'm addicted to the grain, so, for me, only negatives can bring this pleasure ... No more digital stuff at all for 2 years now.
My main goal is to share emotions ... My main doubt is writted on my web site: am I a photographer? I mean, I only shoot the people surrounding me ... rarely strangers, even though I would like to. And from now on I only have one day a week for photography.
Yes, Joannès, you are a photographer. You share emotions through your pictures that I thought was not possible. Subject and image in near perfect harmony.
From now on, I will pay more attention to just that: to share emotions.

the trapped angel
At the royal academy of art in stockholm, they have a lion and a pig guarding the entrance. It has been a saying amongst students at the academy, that you enter like a lion, and graduate as a pig...
However, they have a trapped angel in there too.

Invited guest: Jacek Gąsiorowski
"How can you tell that a photo was taken by an artist and not by relatively talented amateur?"
Jacek says making pictures is like katharsis after working day. He's satisfied with the fact that he's creator and the viewer of his pictures. What is important is to keep in memory important moments of his life, like smiles of his wonderful daugther and wife. Jacek allowed us to take a look into his diary, see some pages of it.

And you, can you judge, what is art, and which pictures were made by an artist?
