Folks,

Anyone on the list used a Rolleimeter?  If so, your thoughts, comments,
etc., would be welcome.

Never used one but always wanted one. I haven't even handled one, but from the photos I got the impression that the glass bar in the center could be a weak/breakable element. Maybe not.
I sure wish there had been something like that for the RolleiMarin. Hard to follow the subject with a reversed image and focus at the same time. A friend of mine who used to manufacture Nikon U/W housings used to have an accessory that pointed two light beams so that they met at the focal point. (Not bright enough to be seen in flash pictures, by the way.) I should have done something similar when I was active in U/W photography. I did develop a slide rule that computed the exposure settings for flash, based on the distance of visibility.
Worked fine, still have it. It was done in the days before hand held calculators so all the calculations were done with log tables. The light loss was based on some work done at Naval Ocean Systems Center in San Diego.
