Some points of ponder

Just bought cheap (but lots of quality from firm which does optics for
varoius optical means) IR- filter. I have plans to do some seroius shots
to LF BW- film with it but how to heck determine correct exposure?

Other point is what I´ve been thinking a lot lately: How to set right
price to picture? My equipment costs money to get + materials aren´t
cheap either. How to set price to a level which is "correct"? ie
customer feels comfortably and I feel satisficed after sold my work?

Have anyone tried making cyanotypes to wood? Or leather?

cheers to all!
