I am planning on doing my own printing using 4x5 negatives within the next few m onths. There are two basic types of film carriers for 4x5 film, one without gla ss and one with glass. The one with glass would seem to hold the film very flat for the sharpest possible print, however, that means I would have to keep four surfaces clean. The glassless carries appeals to me because of its simply desig n, but can I get sharp prints with it. Does anyone have any comments or experi ences with this. The print sizes I plan on using are 8x10, 16x20, and 20x24.
