In \u00a0this era of digital photography we need a computer and printer (and what house doesn&#8217;t \u00a0have at least one of each) to &#8220;process&#8221; and print the digital images. Not so in the recently departed film era.<\/p>\n<p>The film had to be developed and then printed &#8211; usually with an enlarger, timer, thermometer, darkroom trays, safelight (if B&amp;W), easel, and perhaps a focussing aid. And most homes DID NOT have a darkroom and enlarger, etc., etc.<\/p>\n<p>Only professionals and dedicated amateurs possessed the necessary darkroom. Others resorted to community darkrooms (usually camera clubs) or used commercial services. As a youth, I used a high school camera club darkroom, later building my own. The photo here shows my set up in the fall of 1980. To save money I bought 8&#215;10 photographic paper and cut it to a smaller size either before, or as shown, after exposure and processing in a drum (Colour) or trays (B&amp;W).<\/p>\n<p>The enlarger was a <a href=\"http:\/\/www.phsc.ca\/refbooks.html\">Durst M35<\/a>, the top of the line 35mm enlarger featuring all the details noted by Gilbert Durst in Italy. The enlarger takes colour filters which I kept in a Rollei slide box and tray (2.25 in square slides). I used a Variac and a &#8220;true RMS&#8221; iron vane meter to keep the voltage to the enlarger bulb constant (Toronto power seemed okay but Montreal in the 1960s and 1970s had terribly unreliable voltage levels).<\/p>\n<p>The <a href=\"https:\/\/www.ebay.com\/b\/Illuminated-Darkroom-Timers\/29991\/bn_1641934\">Gralab<\/a> timer was modified with a fuse, relay, start button, etc. The Heathkit <a href=\"https:\/\/www.flickr.com\/photos\/target_man_2000\/8587859774\/\">Colorval<\/a> was also modified to have a digital binary timer built-in to match the enlarging lens f\/stop settings. The timer uses a 555 timer chip and a tantalum capacitor to control the chip. Switches and resistors determined the exposure time of 1, 2, 4, 8, 16, or 32 seconds (using two or more switches gives 1 to 63 seconds in 1 second intervals for the truly anal). \u00a0I made all the modifications at home.<\/p>\n<p>The inexpensive <em>pictures in an hour<\/em> shops pretty much eliminated home darkroom colour processing other than for those who wanted to crop or enlarge to a size bigger than the 4&#215;6 or 5&#215;7 prints of the commercial shops like Eddie Black&#8217;s or Japan Camera.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Toronto.
