Thanks for the link.
I see their method is to print on %100 transparency and cut the outer frame. Basically like drawing the frame except on a different layer. I did not think of that because 1) I did not have a %100 transparency film, and 2) I do not have a suitable printer. Not sure if a home inkjet can print on that.
My method is different in that in using the kind of laminating film that I used, which is similar to ground glass in texture, you actually blur out the outer frame and keep a clear section which is your frame. Personally, I prefer this a lot more than a mere printed frame. Even Fuji's own original bracket frames for 6x7 and 6x8 are somewhat difficult to see or pay attention to for me.
It will be a personal preference of course, but definitely thanks for sharing the link.
