Re: Large paper negative step wedge

John,

Paper step wedges (called reflection step wedge instead of transmission step
wedge which we normally use) are availabe commercially. They are used when
shooting when shooting paste-up for negatives for printing. Now that this
step has gone digital, it might be harder to find, but I believe Stouffer
makes them.

Or as you said, you can make one easily.
