I don't realy do anything special,
only a few things to remind.
First of all I know how to develop films for a long time now,
I know the time of developing, I tested that many times and I have a proved workflow.
F. e. Fomapan 100 I use at 100 ASA and develop it most times in Rodinal 1+50 at 7 min. somtimes I use A49 but I prefer Rodinal or R09.
My cameras mostly comes not in a very good condition when I buy them, so I have to clean and to adjust them.
To adjust the rangfinder sharpness control window I put a book in front of the camera at a distance of 39,37 inches and focus it with the focus ring on the lense using a screen on the backside of the open camera,
than I adjust the viewfinder to that distance.
So all subjects at a distance of 39,37 inches are realy sharp on my films.
I never had problems with the shutterspeed, the copal shutter works fine.
To test that I shot a small film with every f-stop om a tripod and if all negatives are ok,
it's fine.
I have to tell, I have a 9.2913 inch roll of fomapan 100,
so I can make small films with only 12 photos.
The photo of my very best girlfriend fits perfect to the camera,
her face is on the right site of the picture and there exactly is the sensor of the lightmeter.
I focus on her face and then I turn the camera left, that was all.
Have to say the f-stop was at f 4 at that moment.
