I'm 40, and I've been shooting analog for, what I dunno... five years? I started with medium format, added 35mm, then large format. I favored medium format in my Mamiya C330 for a long time but I've more recently discovered the joy of taking many more photos simply by virtue of having a Yashica T4 that I can take everywhere. The processing of 35mm is the easiest for me, too, so I do it more often. I know before it's all done I'll be doing tintypes or something. But I'm really enjoying the journey.
