Years ago, before computers took over, I worked with a photo cropping tool; I hope someone can tell me its name.
The gizmo I used was for sizing photos so they could be used in offset printing. They were never sliced physically. I marked them with a grease pen.
It was made of a soft metal, and it was in an open accordion shape, so it expanded and contracted. When opened up, it looked like a bunch of lower-case x's like so:
There were numbers on it corresponding to inches that you used to gauge how big you wanted the photo to be so you could size things.
I have hunted for a picture but can't find one. Any help is much appreciated.
Does anyone know the name of the tool I have described?
