[pinhole-discussion] ortho film

[Laurie Dahl Isacson]

I made a mistake when purchasing film for high school photo classes. Instead of 
ordering Kodalith film I somehow managed to order "Kodak Professional 4154" 
"contrast process ortho film" in  4 x 5 sheets . Has anyone used this for 
pinhole photography? Do you know if I might be able to use this in a teaching 
situation? 
any information would be helpful
