A "film holder" ground glass

[Tim Meisburger]

I have done this multiple times for multiple platforms...but what I never got figured out well is what to do with the ground glass between removing it from the camera and inserting the "real" filmholder. Every time, I pull out the GG and look around stupidly for where to put it while I install the film holder. Usually it goes under my arm, and gets fingerprints on it, or balanced on top the the camera and falls off, or simply on the ground and gets stepped on...for cameras like the travelwide or conversions that require the thing to be used every time, I need to come up with some kind of system for temporarily holding it on the tripod or camera... Maybe some sort of hook, bungee, or magnet. Crack that problem, and I will be truly impressed.

Good point! Mine's always laying on the ground, where I worry I will step on it or forget it. You could always mount a spring back, I guess. But the idea is you don't need a back to it to use the camera. So far, for me, I use a tripod and ground glass about half the time.

This looks great! Weirdly, it looks just like my mahogany one, including the finger groove, but I guess plastic is fits the camera better. Will share your files with others? Here is mine:Attachment 151524

Yes they look pretty alike.
Any reason for the angled cuts off the corner off the glass?
I will upload the files on thingiverse just need to adjust the dimension on the plastic strip, it was a bit hard to make it fit in the slot.

No. No reason for the cut corners on the Travelwide. They are used to check lens coverage on a viewcamera after adjustments are applied, but since there are no movements on a Travelwide, they are superfluous. I just had this ground glass already, so used it.

G'day O,
I like your printed ground glass holder.

To what size do you think this would be a viable method of production?

As for where to put the GG after focusing, I'd suggest building a simple spring back as per my attached image.

The spring back is not practical for rollfilm backs though.

The Calumet C2 120 or Linhof 120 which slide in like a sheet film holder is not practical?

My printer only has 200x200mm print area so this is as big as I can go but it is possible to print bigger with a larger printer.

I have uploaded the files on thingiverse now if anyone want to make their own

If you convert a film holder, there will still be two dark slides to cover and protect the GG when not in use. Mine is nearly as durable as a standard film holder and I treat them the same.

This is a great idea for those who have multiple cameras with no ground glass, only need one glass!

No but seriously as a travel spare this could be really handy!
