I've gotten an enlarging attachment for my Gossen Luna-SBC/profisix. The problem is that it came without a manual.
Right now, I have only managed to use it to set the same exposure at different magnification factors, but I'd like to use it to get at least an initial ballpark figure for centering a test strip.
For example, my paper has an ISO speed of 160. I dial this speed in the lightmeter, turn on the enlarger, and measure the light on what would be a zone V in the final print. Then what? If I read the number opposing the set aperture in the enlarger lens, the time is no where near a test strip indicates. I am supposed to take the time at f/1.0? f/256?
Has any one a copy of the manual? Instructions? any help? While I found the manual for the meter online at Gossen's site, I was unable to find this.
