I've always been a fan of B&W film for portrait work. For many reasons I stopped using film altogether for past few years. It became very expensive to buy film, process (money) and then scan it (time). Digital is just so convenient. However last Christmas I managed to dust off my Hasselblad and I'm hooked again. I still use both however have started to use film more for personal work. Family portraits in particular. I've always liked the skin tones produced by certain color negative films such as Kodak Portra 160NC. Once you get a hang of processing and scanning results can be as good or better. And of course with B&W, if you are using larger format, tones are just superb. I will leave you with following images to ponder.
The following comparison is recently scanned film from 2009 with a digital image taken with a beautiful, small and fun Panasonic G1 camera.
