How many pinholes would you like with your 8x10 hie?
I shoot the Maco in 8x10 and 12x20. But I have to use the 89b filter and rate the film for 1/2 asa to get any shadow detail with the dark filter.
The maco stuff is pricy too. $20 a sheet for 12x20.
I also know Maco is working on yet another IR film to be out next year.
