Hi, everybody,
for a large format camera, these bubble levels which can be mounted on hot shoes need a hot shoe ! I know, this is quite stupid to say that. But I don't know which view or field cameras have one.
And on MF cameras with a hot shoe, I wonder if the hot shoe is really right-angled with the film plane. Not sure it is or not. Never checked it.
The Starrett Cross Test Level No. 136 seems interesting, but I don't see how to fix it on the groundglass or the lens plate. Huge (7x7cm) for a Linhof plate.
On a LF camera, the levelling of the tripod is something essential. Second, the levelling of the camera. And I agree with the idea that there is already a useful tool for that : the groundglass.
I use an angle finder protractor, with a large 360° dial, for levelling the tripod and the camera. The one I used was bought by McMaster Carr. When it was recently broken, I use one from Empire Level (Model 36 Protractor). Only $11.09.
