I found the same trim plate in both the clean and scratch folders. Different captures, same little mark on the back. We're planning FR10 presentation to a camera and people have been sorting cropped images by how convincing the bright line looks.
I can trace this pair back to the plate. Several other crops have no usable identity left. I'd rather lose some training examples than pretend those labels are settled, but am I throwing away useful lighting examples too?
That's a useful result to bring to whoever specifies the lighting. Are they seeing the physical pair as well as your pictures?
