how much exposure?

Toronto. The digital fraternity (and in the waning days of film) have no difficulty with exposure – the camera does the heavy lifting. It wasn’t always so. All of the 19th century (well at least when photography experiments began) and over half the last century, exposure calculation was a major effort.

Ev Roseborough reminisces in this article in issue 23-4 about those earlier times when exposure calculation was both paramount and incredibly difficult for photographers (especially green photographers). The article is reproduced here (click on the icon at top left to see it).

And of course members can also see it in the pdf file for issue 23-4 on the free members-only DVD/thumb drive. Join now – just follow the note above and/or at right. Questions? email Lilianne at member@phsc.ca.
