You could add markings on both pieces of the viewfinder to indicate what the picture ratio is and match it to your canvas. Instead of the skewer you could have a sheet of acetate and just use a marker to draw the rebatment line. The acetate sheet can slide between the viewfinder arms....another idea ...grab a clear plastic clipboard and clip some parallel strips of paper to it. If you paint on a set size of canvas or small panel , this can all be set up before you go outside. Would be helpful for inside drawing sessions with still life and anatomy drawing. Cheers
I also like to take the clear plastic clipboard and use a marker to mark out the same ratio rectangle of the board/canvas. Then I take a sliding carpenters bevel which can be set at any angle and hold it vertically aligned with the left edge. Then you set the angle from the top left corner as ref point to any point in the scene_ transfer this angle to the canvas with a straight drawn line .Now use the right corner and set the angle to the same point in the scene and transfer to canvas. You don't really have to measure any lengths. What you end up doing is triangulating your way around the canvas with a meaningful grid where everything is actually in correct proportion__never mind grid squares , though you may use ref points of 1/2 or 1/4 points around the perimeter to set your angles from. Or you could even use the centre sometimes. This carpenters bevel is the training wheels on your art bike...after a few months you have your eye in and you don't need it. Cheers
Margo, every rectangle has within it an implied square on either side. The implied line that implies the square is the rabatment. You can see that by the way I divide the space with the skewer in this Quick Tip.
You are a clever cookie. Thanks!
Thank you! 😊
Gracias
Thanks for watching.

Paul White, I like the way you think. Thanks for adding these ideas.

Thanks for this one, too.
What exactly is a robotment?
