Thanks Timothy, I started using XP@ after my kidney transplant few years ago. I felt compelled to dust off the old Konica AS2 Rangefinder and transport myself four decades back in time. I love the characteristics and results I get from this film and it's become my go-to for B&W. I also like the C41 process so I can visit my local pro lab and hangout like the old days!
Your pictures and book are excellent
