I recently restored some of my late uncles camera gear.
In Phase one, I developed a dozen or so 4x5 black and white films from his old view camera. I scanned them into the computer and the post processed images were quite nice.
Phase two, I am going to contact print them on his 1940's vintage "Kodak ABC Photo-lab" contact printer. The instruction booklet says how but does not give any exposure times. All it says to do is to double the previous time until the photo image comes out correct on the paper. So the obvious question is how long of an exposure should I start with.
The box is about 8x10 and painted white inside, the glass will hold a 4x6 negative. It has a 7 watt bulb inside and appears quite bright. I plan to use a black slide to expose 1/4th of the sheet at a time, so the question is, what is your best guess a starting exposure time? Do I do 1, 2 4, 8, seconds or 10, 20, 40 80 seconds?
I have never contact printed negatives and it has been 30 years or more since I last used an enlarger. My first impression is to start with #3 arista EDU paper for a bit of B&W contrast but I certainly welcome any and all advice.
Phase three is to restore my uncles late 1930's "Kodak Auto-focus" enlarger, but that is a long way down the road.
