I had never used a cropping viewer before going back well into the 1970s. Just fingers and thumbs to make a crop. My wife got one of those cool adjustable cropping deals a while ago and I had to try it. It sure is a nice tool and helps speed up the process for me.
What I don't like about it - It's too small for me plus it is hard to get it in the same position every time both in distance from my eye plus the relationship to the scene.
I think I might enjoy having a fairly large adjustable cropping frame attached to some kind of flexing gooseneck or adjustable arm of some kind that will hold it in just the right spot so my hands are free to paint and I can just glance through it easily until I get the scene blocked in fairly well. Once I have the key lines and shapes on the panel I don't need the tool anymore, so it would be a temporary thing.
Have any of you tried something like this? What did you use to hold the cropping tool? I want it to be pretty light weight but strong enough that it won't move on its own or if lightly brushed against. Spring clamps on both ends seems the most logical.
Something like this but shorter and less expensive might do the trick
