I understand that fallback to AHD is automatic when 'libraw can not do otherwise'.
But my question was about the value stored by user_qual after dcraw_process.
I've made this test: set user_qual to 18 (to be sure to activate the fallback to AHD), call of dcraw_process, and then display the value of user_qual which were still 18. So, is there a solution to know if the fallback has actually happened?
