So in two weeks, I will be shooting my cousins wedding. Now of course, she has a regular photographer that will do the regular stuff... But she likes a bit of the old fashioned. I told her I would bring my Speed Graphic and I might even ware a trench coat and hat. So, I will be shooting indoors in a restaurant. I'm shooting HP5+, and I have number of #25B and #11 bulbs. Now, since I wasn't alive in the 50's, what is the best way to set up the camera so that I can use the rangefinder or wire guide. I am very comfortable with judging distance, so perhaps setting the rail at 10' is good enough? Also, just to double check, when focusing using the scale, I should set the mark above infinity and 100 to whatever I want (like 10?)? Thanks!
