does anyone know if a ground glass was made for it ?
i have searched some of the specialty sites and since i don't know the code names or numbers
i can't figure it out. if i have to, i'll adapt a different maker's gg, my toyo and rollei are too big ...
as a last resort i have had people wheel me around on a dolly
but going over curbs is a real PITA
John, hi there and look no further than what I consider the most useful gadget, namely the Leitz Vidom universal finder as shown in my Avatar. For those not familiar with this little device, let me mention that many years ago I noticed 2 pictures of HCB with a camera, one taken when in his 20’s and one taken when in his 50’s and on both pictures he has a little device slotted into the hot shoe of his Leica. For many years I thought this was just a viewfinder that provided an angle of view for a specific lens not built into the bright-light frame finder of the camera. However, some years later I was reading a student’s personal study written about another magnum photographer. I even remember the actual day and where I was standing in the room, as it hit me like a sledge hammer. This other magnum photographer described how Henri showed him what this device did.
In short, it allows adjustment to view at a variety of focal lengths (something I never use it for and probably neither did HCB I believe) and it also adjusts to correct parallax, but here is the best bit, it also allows you to view the image inverted in a horizontal plane, should you wish to print shiny side down for compositional reasons. This means you can view from viewfinder to Vidom finder and see the image flipped horizontally. However, that is not all, its best function is that by turning the small prism at the back you can view the image upside down in both landscape and portrait format, thus giving the objectivity of shapes and forms only normally seen when working with LF.
