Lasse Halvarsson, Leif Jäderberg, Gun Wigh and Bo Östlund were all educated by the photo legend Evert Jäderberg in the 1960s when the local newspapers did not have permanent photographers.
All of the quartets later became full-time press photographers and have now ended their careers.
Now they want to pay tribute to their teacher with an exhibition in the Art Gallery in Sandviken.
Gun Wigh
On 16 August 1982, the Maranata preacher Arne Imsen held a meeting in Folkets hus in Gävle and the punks in town decided to disrupt the meeting.
Police arrived at the scene, the riot escalated and one of the punks was shot in the leg.
Gun Wigh was of course there and took pictures.

Leif Jäderberg
March 1, 1971 four people are shot to death in the so-called Tingshus murders in Söderhamn.
Leif Jäderberg monitors the subsequent district court hearings on the murders and sneaks a picture during the trial.
Expressen puts the picture in the newspaper at night - but chooses to take it out again because it is not allowed to take photos in the courtroom.
That picture of Gunnar Bengtsson and his lawyer Henning Sjöström is the only one of the 100 pictures in the exhibition that has never been published.

Bo Östlund
SVT Gävleborg's longtime photographer Bo Östlund started just like the other three with Evert Jädeberg and went on to work for many years for the evening newspapers.
Among other things, he watched the US Open at Flushing Meadow in Queens, New York, when Björn Borg needed bodyguards.
This picture ended up in the New York Post, among other places.

Lasse Halvarsson
Tomas Ledin plays at home in Högbo in 2006 and he points with his guitar at Lasse Halvarsson who is in the photo ditch that he can come up on stage and take photos if he wants.
Then he takes this picture where it is almost possible to identify everyone in the audience.
