Exakta VX IIa Shutter setting dial for B, T, Speeds c1958<\/p><\/div>\n

Toronto<\/strong>. Over the years from photography’s beginning in 1839 to current times there have been a few trends. Cameras have gotten smaller. Images became more realistic beginning with monochrome photos across part of the visible spectrum, then across all of it (panchromatic), colour – first by hand then with rudimentary dyes trying to mimic life and finally digital colour covering a much wider gamut. Cameras and processes were very technical and difficult at first on down to so simple anyone can take a decent photo today. Media and lenses were dog slow at first, moving on to super fast media and fast lenses. Costs have continued to spiral downwards.<\/p>\n

In a post a few days back called “why the tripod?<\/a>” you met ‘B<\/strong>‘ and ‘I<\/strong>‘ – the Bulb and Instantaneous shutter settings used when dry plates came into vogue (c1870). The instantaneous setting bloomed as media increased in speed. ‘I<\/strong>‘ changed into a series of shutter speeds eventually reaching and exceeding 1\/1000 second. And the Bulb setting, where you hold down the shutter release to keep the shutter open, was augmented by a ‘T<\/strong>‘ setting where you pressed the shutter release to open the shutter and then pressed it again to close the shutter. The ‘T<\/strong>‘ stands for Time (sometimes it was ‘Z<\/strong>‘ or Zeit which is Time in German).<\/p>\n

Over the years after shutters came out, the shutter settings often reverted to either<\/em> ‘B<\/strong>‘ or ‘T<\/strong>‘ since the speed timed could be measured using either setting.<\/p>\n","protected":false},"excerpt":{"rendered":"
