    I asked this question about 30 years ago of one of the old-guard cigar chomping newspaper photogs that owned a pro-lab that I worked at. His answer was that as Roger stated, to cut down on what he called "frame flash", a bleed of light on the general easel area not part of the negative information.

    I guess that the size variability issue is a genuine concern for masking by a carrier. I have filed out my beseler 35 carrier, even though FF ones are available. Seems like sellers of those think they are plated with gold. More often than not, I use the negatrans, which cuts more off the bottom of the frame due to the transport mechanism. A habit has been created to allow a little more frame space in composition.

    A new issue I have run into is with the Mamiya RB backs. The newer SD backs have a slightly larger frame area than the Pro and ProS... It goes back to what old Cigar Bob said about composition, "if it's too tight it ain't right..."

    I have a Saunders 4550 and it's glassless carriers are pretty close to the correct size -- I've not had to do the filing that I had to with the Bessler. Additionally, their 4x5 glass carrier is slightly larger than 4x5, and it's meant to be used with a masking frame that allows you to (hypothetically) crop at the negative stage, but in reality, allows you to mask the flash mentioned in the previous message.

    Well I too have the Saunders 4550 and the 6x6 neg carrier is just about full frame. I like it a bit wider so I will do some filing later today (I just got this rig).

    David, to cut down on possible spurious reflections from your filing-out, run a black permanent marker over the bright metal surface. And be ABSOLUTELY sure to fine sand the edges (especially the 90) smooth to prevent scratching. How do I know this???

    thanks patrick. i have filed a bunch of carriers already and have been lucky enough never to have a problem.

    I can't believe Saunders got so close but didn't go the extra milimeter.
