Continuing my progress on preparing to do 4×5 daguerreotypes. The camera currently only has a “hat shutter” so I have been looking at available shutters for my large lens – the only new one available seems to be the Packard shutter. This item, still made by the son of the creator is available for $850 in the size of interest to me. Time to save up, time to watch ebay, time to let the design ideas start disturbing my sleep again.
I also made a trip to Home Depot today for a domestic repair item and picked up some JB weld for bromine testing. Maybe that will be rugged enough to line fuming boxes with sheet glass. I’m also planning on testing some for adhesion to a scrap of textured PTFE I have left over.
Three day weekends are great.
I was going to write a short post about today being the anniversary of the first announcement of the daguerreotype, but a half hour of research revealed that the real story is more complicated – announcement today – perhaps first printed tomorrow, possibly unpublished circulars from earlier dates, first english language announcement, etc., etc., etc. So I will just say Happy Daguerreotyping! and if you are a history buff, there are plenty of good sources for looking into the particulars of the dawn of photography. Here are two: http://daguerre.org/resource.php and http://www.daguerreotypearchive.org.
Did some testing of liquid bromine on various kinds of plastics today. Only PTFE was non-reactive as far as I could tell. Have plastic samples now sitting in a container with iodine crystals.
