Gunner’s Off Camera Flash

Those lucky few who attended on the eve of the long week-end were certainly very glad that they did and were treated to a really super presentation by the “Gunner”. The Gunner’s presentation introduced members to the concept of off camera flash, and using the Club’s new “tethered” system cable the audience were able to see at first hand the results literally straight out of the camera. Utilising a well-practiced “instructional technique” and a style all of his own the Gunner explained and demonstrated as he went along just what he was going to do, how he did it, and the resultant images were immediately available on the big screen for the audience to enjoy and appreciate just what had happened. Using 1, 2 then 3 light set ups then 3 light & projection. We got a superb overview of lighting concepts and techniques.

Guerillero heroico by Alberto Korda 1960

The day before Alberto Korda took his iconic photograph of Cuban revolutionary Che Guevara, a ship had exploded in Havana Harbor, killing the crew and dozens of dockworkers. Covering the funeral for the newspaper Revolución, Korda focused on Fidel Castro, who in a fiery oration accused the U.S. of causing the explosion. The two frames he shot of Castro’s young ally were a seeming afterthought, and they went unpublished by the newspaper. But after Guevara was killed leading a guerrilla movement in Bolivia nearly seven years later, the Cuban regime embraced him as a martyr for the movement, and Korda’s image of the beret-clad revolutionary soon became its most enduring symbol. In short order, Guerrillero Heroico was appropriated by artists, causes and admen around the world, appearing on everything from protest art to underwear to soft drinks. It has become the cultural shorthand for rebellion and one of the most recognizable and reproduced images of all time, with its influence long since transcending its steely-eyed subject.

Millimetres V Pixels

When converting DPI/PPI to mm for printing purposes you should have a minimum of 12 pixels per mm. See the attached scale for printing the perfect image.PixelRatio This is just for reference against your own calculations. The left column follows the format and the mm size for your print and then you follow across the pixel dimensions to supply the printer. Most users/printers would prefer the size without bleed and they normally add 5 or 10 mm of paper/stock so that the print can be easily mounted. So For example I normally print 2:3 the ratio of my sensor with print size 37.5 x 25 ( 10 x 15 inches ) This means that according to the scale that at 300 dpi resolution I need pixel dimensions of 2953 x 4429.
