what a really sweet image to work with!

Thanks for showing your method. I don't understand why you can't rotate the image to get it horizontal then draw a line for your 100 micron scale then just copy and paste your bar to the other photo which is at the same scale ?

I was really looking for how to do it in Photoshop but I guess the same principle applies

Why not just rotate the line from the calibration picture? Zoom in and rotate for best results.
