Remember, candlelight has a very low color temperature; it requires more exposure than measured to get a good negative. Anyway, don't expect much shadow detail; at film speeds like 3200, the speed of the film is nominal - there really is no way of measuring a threshold over base + fog because there isn't anything in the lower zones anyway (the shadows go black). - ----- Original Message ----- From: "Simon Wong" <drsimonwong@hotmail.com> To: <leica-users-digest@mejac.palo-alto.ca.us> Sent: Saturday, October 27, 2001 7:35 PM > Date: Sat, 27 Oct 2001 08:26:52 +0100 > From: "Mark Pope" <mark.teampope@ntlworld.com> > Subject: [Leica] Advice on getting good results with Delta 3200 > Message-ID: <005301c15eb8$c0060d20$cf5e6bd5@oemcomputer> > References: > > Dear all, > > there is a candlelit vigil in our town centre this evening (it starts at > 19:00 BST), to commemorate the events of 11/9 and also to protest about the > bombing of Afghanistan.
