I've been searching the internet and this site and I cannot find a good answer to how people are masking their LF film for contact prints. I am trying to create 4x5 prints on 5x7 paper so there is a fairly significant border around the print.
I am making cyanotypes and if I make cover an area of the paper with sensitizer that is larger than my negative I will see marks from the film on the finished print. This is most obvious in the film notches and the parts of the film that were not exposed at all, but still alter the print.
I need to make a mask that is slightly smaller than 4x5 so only the exposed part of the film is printed. My first attempt at a mask was a cheap frame mat and that did not work so well as the mat was not completely opaque. Is there a "best way" or "better way" to create a mask for this purpose? Print masking with a contact frame must be a lost art because I cannot find anything on the subject so I assumed there was no magic to it.
My question is more about the trend. If the internet is any indication the current "rage" in alternative processes is to use a brush to coat the paper and then leave painterly brush marks along the edges of the picture area. Most of these seem to contain the entire negative, but have no film marks that I can see. Maybe they are using lith film or digital negatives?
In any case, I have a hard time finding any cyanotypes or newer alternative process prints on the internet where someone has "properly" masked the image during exposure. Is this not using a mask a new trend to show the paper was hand coated or has this always been the case and a tradition?
