Sorry if I ask stupid question. I will start my first film-development in this weeken. I already have important reagents such as parodinol (very clear one), fotospeed fx30 and tetenal mirasol 2000 (wetting agent). But I still have no idea do i have to use stop solution after parodinol-developer. I already have gracial acetic acid and ready to dilute it immediately if you suggest that it's really important. Thank you all.
